PHOTTIX MITROS+ – With Built In TTL Radio Announced

Phottix have officially announced the new Mitros+ flash unit for Canon, with full TTL Radio Transceiver built in! Similar in function to the Canon 600EX-RT.

UPDATE – Nikon and Sony version Mitros+ are also now available.

The new Mitros + retails from around $399, making the Phottix system significantly more affordable than the Canon option, while still providing a solid reliable system with 2 year warranty as standard.

Lower price is not the only advantage though, the Mitros + provides a number of quality receiver options, for firing other TTL speedlites and manual studio flashes as well. And also offers features like Second Curtain Sync, and full functionality with many pre 2012 camera and flash models (unlike Canon’s system). For Nikon and Sony owners the Mitros + will be an even bigger advantage, as they do not currently have their own radio based flash system available at all as yet.

Phottix MITROS +

Announcing: The Phottix Mitros+ TTL Transceiver Flash is the best of Phottix’s gold-standard products all-in-one.

What’s the + ?
+ Built-in Odin Transmitter
+ Built-in  Odin Receiver
+ Built-in Strato Receiver
+ Memory Functions

The Phottix Mitros is a powerful and durable hot shoe flash that has proven popular since it’s release earlier this year. The Phottix Mitros+ adds significant functionality, allowing photographers to not only use the Mitros+ on or off camera, but also to control and trigger remote flashes by radio signal. The Mitros+ is a new industry landmark and was developed with input from professional photographers, world-wide.

Main Features:

GN: 58 Canon-compatible TTL Flash

Built-in: Phottix Odin Transmitter and Receiver, and Strato Receiver

Optical Slave

Canon-compatible Master/Slave IR Triggering Modes

ETTL I/II, Manual and Multi Stroboscopic Modes

High Speed Sync and Second Curtain Sync

AF Assist Light

Flash Zoom: 24-105mm

External Battery Port, 3.5mm Sync Port

Quick Flash Mode

Phottix MITROS +

Use the Mitros+ on-camera as a key or fill light, and control and trigger other Mitros+ flashes or compatible flashes using Phottix Odin Receivers.  Built-in Phottix Odin and Strato II Receiver functions mean the Mitros+ can be used with many existing Phottix flash triggers.

The Odin Transmitter in the Mitros+ operates similarly to the Phottix Odin TCU. Photographers have three groups, A, B and C, and four channels to use. Control TTL EV adjustments of +- 3 in 1/3 stops and manual power from full power to 1/128 in 1/3 stops. The Mitros+ can be triggered by existing Phottix Strato II Multi transmitters.

In additional to the Transmitter and Receiver functions, the Mitros+ is also a flash. Perfect for fast-paced wedding and event photographers or photojournalists shooting where an on-camera TTL flash is a must. The Mitros+ is truly all-in-one.

The easy-to-use Mitros+ also offers TTL, Manual and Multi Stroboscopic modes, a rotating and elevating flash head, high speed sync, second curtain sync, external battery port, 3.5mm sync port and custom functions.

Odin Functionality
With Phottix Odin functionality built-in the Mitros+ be can used to trigger Phottix Odin and Strato Receivers. Likewise: You can trigger the Mitros+ using a Phottix Odin TCU or Strato II Multi Transmitter. Using the Mitros+ in Odin Transmitter Mode provides the same functions found on the Phottix Odin, including:

Remote power control of groups in TTL with +/- EV adjustments – 3 stops in 1/3 stop increments  – 18 different levels

Remote power control in Manual Mode: Full power to 1/128 in 1/3 stop increments.

Mix TTL and Manual flash – Fire some groups in TTL, others in manual.

Remote power control in A:B ratio modes with +/- EV adjustments.

High speed sync – Shutter speeds up to 1/8000 sec.

Second curtain sync functions

Remote flash head zoom adjustments – auto or manual

The Mitros+ will control and trigger other Mitros+ flashes in receiver mode or Phottix Odin Receivers. Like the Phottix Odin, the Mitros+ has a backlit LCD and is intuitive and easy to use.

Phottix MITROS +

Mitros+ TTL Transceiver Flash

Strato Functionality
The Mitros+ has a built-in Strato II Multi-compatible receiver.  Existing Strato II Multi transmitters can trigger the Mitros+.  The Mitros+ can also trigger Strato II Multi and Strato I Receivers, and Atlas II Transceivers in Rx Mode, when used as an Odin TCU.

Memory Functions
New with the Mitros+: Built-in memory functions. Three sets of flash and function information can be saved in the Mitros+’s memory and be quickly recalled when needed. Do you use the Mitros+ in different modes for different situations? Quickly recall saved set-ups for fast use.

The Phottix Mitros+ TTL Transceiver Flash for Canon will be available in October 2013. A Nikon-compatible version is scheduled to be released by the end of the year.



The Mitros + solves one of the most common problems encountered by many wedding and event photographers currently using the Canon system. That is how to fire other non Canon (non 600EX-RT for that matter) flashes and studio lights without having to cobble together more transmitter units on the camera.

The Mitros + provides a number of quality receiver options for firing other TTL speedlites and manual studio flashes as well. The flash can then be mounted securely and reliably directly on camera hotshoe without any pass through hotshoes or extra transmitters needed.


Phottix Mitros Plus Comparison

Of course using Mitros + flash units off camera there is no need for any extra receiver units for those, which is a huge convenience saving carrying extra gear and extra battery management.


Price and Availability –

The new Mitros + retails from around US $399. Canon version available now, and a Nikon-compatible version is scheduled to be released by the end of 2013.

    What I just ask me: does the Mitros have a head lock mechanism? I’m in the market for a Yongnuo 568 since my SB-800s don’t work together with 622n. But they have no head lock and I’m a bit annoyed about that.

    • Andy C 8 years ago

      I am following all these threads with great interest….have been a multiple light event shooter for more
      years than I care to admit…remember the original clutsy Hawk radio slaves and all their quirks. It is
      a shame that camera manufacturers have not seen to design products that actually work for us guys with all the modern tech there is now. Very disappointed that ODS will not be available with this flash as I thought it might be a great solution for me in tandem with the cheetah unit. I currently shoot with Canons and 600 rts…the radio works great, but the adjustment procedure is very fiddly and not intuititive…too hard to change quickly on the fly. Also the 600’s do not have enough power and tend to shut down too easily with multiple pops…so I use an old Quantum Q flash as my second
      light…which is a a very reliable powerhouse..shooting multiple setups thru and umbrella at 1/2 power, I trigger it with the Stratos unit on the hot shoe and can still mount my 600 on the camera for fill and controlling other 600’s. I can shoot until my finger falls off. The drawback is this flash does not have remote adjustability and no HSS…so I have to use a 600 ex outdoors for this feauture. Would love it if Canon made a powerful flash like the Quantum with full remote capability and HSS …also make
      dedicated buttons to adjust power levels. That would be my dream setup….any electronic engineers here? Maybe we could cobble up something.?

        Hi Andy,

        Electronic engineers are generally the problem unfortunately! They just don’t think like you or I as far as user friendly interfaces go. The Canon flash system has always been a classic example. Its a constant battle I’ve come to realize will just keep going on as long as new products are made.

        I would let Phottix know that you would like ODS in the Mitros+, and compatible higher power flash units. As the more people that ask the more they will take note.

        I think Phottix will eventually have compatible higher power flashes available though. This is where most companies are headed with an integrated system now. Thanks.

    Hi Armin,

    The Mitros doesn’t have a head locking button, but the difference between the head tilt & swivel from the Mitros to the YongNuo flashes is probably the most obvious tell-tail of the large difference in build quality. The Mitros head movement is silky smooth, where the YongNuo flashes are quite janky and harsh.

    If you’re wanting the head to lock, to put a lot of weight on it or something like that, then there wouldn’t be much advantage there with the Mitros there I don’t think. Twisting Either one will put a lot of stress on a pass through hotshoe eventually, though the Mitros may be a little kinder there. But the Mitros + built in radio hopefully eliminates the need for pass through in most cases.
    I’m not sure what you mean about the SB-800 and YN-622 though. They had a bug at the start, but they should be fully compatible now. The only thing they won’t do is act as a master on top of the YN-622, but either will the YN-568EX at this stage. If you’re going to go the Mitros route I think you would be far better off trading the 622 in and going all Mitros +. No risk of compatibility issues etc down the track then.

    • Armin 8 years ago

      Of camera flash it’s not a big deal not having a head locking button. But on camera TTL shooting with a e.g. Gary Fong style dome it is an issue ahing no locking button.

      Anyway, I bought four 622n tree weeks ago and they don’t work in TTL mode with my two SB-800s. In 80% they fire (wrongly) at full power. Same problem as reported on several forum I checked. And since no update posssibility on 622s, no chance that will change.

      Are there different software releases of 622n on the market? So I just had bad luck?

      • Armin 8 years ago

        Sorry for bad English. Should have checked twice…

        • David C 8 years ago

          The date manufactured (at month level) is listed in the battery compartment. The date Yongnuo gives is June 20 for the version that works for the SB-800, so any with a month marking of July or later theoretically should work. However, I bought two new ones that are marked as July and they don’t seem to work for me in full TTL (but could be that I’m doing something wrong). The SB-800 always worked controlling manual mode fromt eh YN-622Ns though so I still use it.

          The Odin ecosystem is looking pretty interesting though…..

          Question on the Mitros, is there a separate mode that has to be set for HSS (like you have to do on the Yongnuo’s) or is it automatic like on the Nikon SB flashes?

          • Armin 8 years ago

            Thanks for the hint, David. What a luck: my ones are made 6/2013 🙁

          • Author
            Flash Havoc 8 years ago

            Thanks David,

            Yes the Mitros allows you to turn HSS on and off.

            At or below the cameras x-sync it should still automatically disable though even when turned on.

      • Author
        Flash Havoc 8 years ago

        Yes there was an update which fixed the SB-800 issue as far as I understand. The last update mentioned here was the end of June.

        So if exchanging you would need to make sure the seller actually has updated versions to replace them with.

  3. Meddin Studios 8 years ago

    Can we trigger a camera with an Odin Rx/Tx or do we need to use a Strato for that?

    • Author
      Flash Havoc 8 years ago

      No you would need as set of Strato II or Atlas II to do that.

      They would be separate from the flash triggering (as in set to a different channel), so you can really use and shutter release for that. But using Strato II or Atlas II would provide some compatible back up triggers for the flash system then too.

  4. Ricardo Gomez 8 years ago

    Amazing. Phottix is really on top of it. Love their Odin system.

  5. Gareth 8 years ago

    They haven’t said anything about this having ODS. I want something that will trigger my speelights and my hensel porty optimally at 1/8000 with my D700.

    I am hoping this will be the answer. Less things to lose is a major advantage to this and odins.

    • Author
      Flash Havoc 8 years ago

      Hi Gareth,

      Unfortunately there is no ODS with the Mitros +, only the Odin. It would have been the ideal solution for the Cheetah Lights/Witstro HSS mode as well (with a TTL flash on camera). The Odin will have to do for now. Thanks.

      • Gareth 8 years ago

        How did you find this out? Is it something they could fix with a firmware update?

        • Author
          Flash Havoc 8 years ago

          Hi Gareth,

          It is stated somewhere by Phottix, I’d have to find where it was written now, but its not implemented in the Mitros +.

          Yes they should be able to implement it with a firmware update, drop them an email and let them know it would be important to you for sure.

          • Gareth 8 years ago

            I left a message on their facebook page.

            Any chance can do a af beam comparison between this and canon and nikon flashes?

          • Gareth 8 years ago

            Got a response back. They said;

            “ODS will most likely not be implemented to the Mitros+. That poses a lot of technical challenges when an on-board flash / transmitter combo is use.”

          • Author
            Flash Havoc 8 years ago

            Thanks Gareth,

            I would guess the main issue is likely that the ODS is currently just a global timing adjustment, so an adjustment will also effect the on camera flash.

            YongNuo are adding a timing adjustment via each group to the coming YN-622-TX. So you never know, Phottix may update the ODS at some stage yet too.
            Yes I should try and do an AF assist light comparison. The Phottix light is similar to the Canon/Nikon ones though, in that its 2 separate lights that project long vertical or horizontal lines, depending on the focus point selected. And basically covering all focus points. Maybe not quite as clear as the Canon light, but in the same area.

            The YongNuo AF light is very different though, its a much brighter and sharper, lazer style projection. But only in a small circular area basically covering the center focus point. A combination of both would really be something interesting.

  6. T Salaz 8 years ago

    I shoot with a canon 5d mark iii . Since I don’t have a built in flash I assume I would still need a trigger to fire this off camera ? I’m kinda new with triggers and off camera lighting but I’m looking to buy two maybe three lights to use off camera , this seems like a great option since I was a few weeks from buying the canon 600rt system for much more then what there asking for this . Any info would be appreciated , thanks !

    • Author
      Flash Havoc 8 years ago

      Hi T Salaz,

      Yes you would need the Odin transmitter if you didn’t want to use one of the Mitros+ flashes as the transmitter.

      That’s probably one slight catch at them moment, because as far as I’m aware the Odin transmitter is still currently only available as a set with at least one Odin receiver, $329 for the set.

      Hopefully Phottix will offer the Odin transmitter separately at some stage but for now you may need to buy the set. Thanks.

      • T Salaz 8 years ago

        That’s still a great deal concidereing I would need to buy the canon rt trigger plus the cost of the two speedlights , thanks i think I’ll have to give this brand a try

  7. Mike Anderson 8 years ago

    Can I mix Canon Flashes and fire/sync (TTL/manual) these all together? I love the Odin system and use it with up to 8 550ex flashes. WOuld like to start buying these instead of 550’s on eBay.

    • Author
      Flash Havoc 8 years ago

      Hi Mike,

      Yes that is correct. You can use the existing Canon flashes with full function, provided they are attached to Odin receivers. The Mitros+ are the only flash unit which can act as a transmitter though (or the Odin transmitter). Thanks.

  8. Stephen 8 years ago

    so if i wanted to use the Mitros+ with my Canon ex ii as the slave i would need an Odin receiver on the 430 but if i wanted to trigger the Mitros+ remotely I would need to use a Stato II receiver on the Mitros+ ? … why is that? doesn’t make sense why a mitros can’t be triggered by an Odin transmitter.
    that way i wouldn’t have 2 buy 2 different versions of xmitter/receiver(Odin/stratos/.
    plaese advise as i love the Odin flash and tcu but currently only have the 1 Canon 430 exii flash.
    since i wanted a second and more powerful flash anyways, I’m thinking getting the Mitros+ flash instead of just the Odin tcu would be ny better choice for me to trigger my off camera flash (the 430) which i could either combine with or without the main mitros+ firing.

    can i use a Sekonic flash meter with the Mitros+ ?

    • Author
      Flash Havoc 8 years ago

      Hi Stephen,

      You don’t need any separate receiver with the Mitros+, as the Odin receiver is already built into the flash. So the Mitros+ is directly compatible with the Odin TCU.

      I’m not sure about the Mitros+, but the Odin TCU for Canon recently received a firmware update which allows a light meter to be used with the Odin test fire button when using manual power settings. This update fires the low power pre-flash first, and a couple of seconds later the main flash fires at the correct power level. So the light meter can take a reading of that main flash without being confused by the pre-flash. I would assume the Mitros+ would have the same system, as the Odin TCU is built into the flash. Thanks.

  9. Nick 8 years ago

    I have heard these overheat very quickly and you can only fire a handful of times before the overheat protection kicks in. It’s not necessarily the flashes are overheating but the software is preventing them from firing.

    In your testing you fired off a bunch before it kicked in. Have you noticed anything change or has the overheat protection kicked in too early? Unless they do a firmware update this could be a major issue for me at weddings when things happen quickly and I want to fire a bunch.

    Just seeing if you found it to be a problem? Thanks again,

    • Author
      Flash Havoc 8 years ago

      Hi Nick,

      The Mitros I have doesn’t like full power for long, but at 1/2 power or less I don’t really see an issue with the over heat protection. So if you were maxing it out with ETTL exposures constantly your probably going to have an issue like at full power.

      I’m not sure if Phottix may have even changed the software though, as my flash slows down to 5 second recycle well before the overheat protection light comes on, so it never actually goes into overheat protection. While I have read some others saying the light symbol comes up as expected.

      Unless you’re maxing them out its likely not going to be a problem in any case. But once bare bulb flashes like the Godox Witstro go TTL they will be pretty hard to resist, as you can just bang away constantly with those even at full power.

      • Nick 8 years ago

        Awesome! Yeah I usually shoot at my receptions around 1/4 power, give or take. Good to know!

        So wait, when do you think the Godox’s will go TTL?! But I am loving the theory of these Mitros+ with the ease of changing power right on the flash, right from the camera having ttl with no recievers and using a flash on camera as well. Doesn’t seem any better for my setup.

        • Author
          Flash Havoc 8 years ago

          Hi Nick,

          I really don’t know how long it will take Godox to go TTL, but when they do I would expect a fully integrated system (except receiver modules plug in, rather than built-in).

          It could be just as likely that Phottix offer a Witstro style of flash that’s integrated into their system first.

          At least by this time next year I’m sure we will have a lot more options, and complete systems.

      Is there any review of the Nikon version?

  11. Todd 8 years ago


    I’ve got a question, hopefully you can help with this one…..

    I have the Odin TCU (1.5) with a Mitros+ flash. The Zoom function seems to confuse me a bit.

    When I have the flash in wireless “Odin RX” mode (for off-camera flash) the zoom function will only work in “Azoom” mode while using the TCU to adjust flash zoom. I thought this would be the other way around and set to “Mzoom” on the flash for manual zoom adjustment from the TCU?

    So, If I leave the flash on “Azoom” won’t the camera lens zoom function adjust the flash zoom I just set manually and override my previous flash zoom adjustment? I haven’t actually tried using the lens zoom, but I’m quite confused by this and I should not be…..hope these questions make sense. Thanks!

    • Author
      Flash Havoc 8 years ago

      Hi Todd,

      I only own the original Mitros and Odin (1.5) at this stage, so I don’t have the Mitros+ here to study in detail yet. And also the Zoom function on the Odin is one thing that is terribly confusing, I tend to avoid it altogether just because the interface is really annoying for it.

      But Azoom is the same with the Mitros, I don’t think there is anything wrong there. The flash should be left in TTL and Azoom so that the Odin TCU can take control of it.

      The camera lens function won’t effect the flash zoom as long as you set that group to “M” on the zoom screen of the Odin TCU.

      Once you go into the zoom screen each group can be set to M or TTL (by pressing the MODE button while a group is flashing), TTL is for auto zoom to follow the lense.

      So just go in set all 3 groups to M to be safe, and then never touch the zoom button again 🙂

      (Its actually not that bad, but the zoom is annoying to adjust).

      • Todd 8 years ago

        Thank You!! Your explanation was exactly correct!! You are the best!

        Press the zoom button on TCU, then select either TTL or M. It’s makes sense now because once you press the “Zoom” button you are only adjusting for the Zoom function and no other function to the flash. There is a little “zoom” title that displays under the battery icon when you are making the selection for zoom settings as well.

  12. Mitch W 8 years ago

    Just received one of these Nikon compatible versions.

    Two questions regarding issues I’m seeing:

    Bounce flash. In TTL mode, direct flash seems to work well, though a little less consistent than my Nikon SB 800. When I bounce, the Mitros+ under exposes by 1 to 2 stops. Now with my SB 800 I tend to add in a +.3 compensation to help with the slightly flatter look of bounce light. But the histogram with the Mitros+ is showing clearly well over a stop under exposure when bounced.

    Manual firing. When set to manual at 1/4 or 1/8 power, My Nikon SB 800 will fire off 4 to 5 pops in a row, albeit with slightly diminishing accuracy nearing the end of maybe .25 stop from the first exposure. So the SB 800 keeps up with occasional 2 or 3 shot sequences taken with the drive set to 3 fps.

    With the Mitros+ set to 1/4 or 1/8 power manual, I get 1, maybe 2 pops in a row at the same settings before the flash wouldn’t fire. This was triggered: optically; with an on camera Odin transmitter and the flash set to Odin receiver; with the flash set to Strato receiver and a Strato transmitter on camera.

    It made no difference whether I had an external battery pack attached. I could still only get 1 or 2 pops at such a low power setting.

    Anyone have experience with this?

    • Author
      Flash Havoc 8 years ago

      Hi Mitch,

      Thanks for that. It sounds like the Mitros+ for Nikon needs some refinement then still.

      I only have the Canon Mitros (not +) and after the latest firmware at least, it will fire like a machine gun at 5fps 1/8 or 1/4 power with at battery pack attached. 10 or 20 consecutive shots no problem without missing a frame.

      Without a battery pack I could still get 10 or 12 shots at 1/8 power and slower 3fps. At 1/4 power 3fps it will drop the 4th shot, and fire again on the 5th. I tried the Godox V850 as well and that was the same.

      So your Nikon Mitros+ is quite a way behind then. I don’t know if that is because they are not up to the same spec as the latest Mitros firmware update.

      I’m not seeing the bounce under exposure issue with the Canon Mitros either. There could well be a metering issue there, but I’ve found the Mitros is 1/2 a stop less power when bounced compared to the 600EX-RT. So I would just check to be sure you’re not simply running out of power in TTL.

      I still don’t think the Canon version Mitros is quit right though either even after the firmware update. That update was a big improvement, but the Mitros will still only do 20 to 30 consecutive shots at full power, before going into overheat protection. Compared to about 50 with the 600EX-RT.

      But with a battery pack the Mitros will only do 10 consecutive full power shots before overheat cuts in. I can understand they would cut the number back because these battery packs are crazy fast now, but that is too harsh.

      Also at lower power levels 30 shots can still bring on overheat protection, which is not right.

      So I still think they have some revisions to do with the Canon version as well. But it will now recycle very fast now while not in overheat slow down.

      A lot of people never even commented on this before the firmware update though, where the overheat protection was really over excessive.

      So yes, definitely let Phottix know, and hopefully they can address these with a firmware update. Thanks again.

    Is phottix mitros+ and phottix strato ttl is a good combination?

    • Author
      Flash Havoc 8 years ago

      Hi Aaron,

      Not really, as the Strato TTL would only fire the Mitros+ at most. You could do that with the cheaper Strato II manual triggers.

      A better combination is the Odin transmitter and Mitros+ set. That provides full function and control then. Thanks.

      • Aaron 8 years ago

        I think so. But the strato II can do only at max 1/250 of a second. Is the FEC of strato ttl works great with mitros+?

        • Author
          Flash Havoc 8 years ago

          Hi Aaron,

          No, the Strato TTL are not really compatible with the Mitros+, other than simply firing them. Unless you attach a Strato TTL receiver to the flash as well

          The Mitros+ have an Odin TTL and HSS enabled radio receiver already built in though. So it doesn’t make sense to add Strato TTL radio transmitter and receiver (which still have much less function than the Odin).

          The Odin transmitter and Mitros+ flash are designed to work together with full functions.

          If you really just want the Strato TTL, then you could just get the original Mitros flash (not +) and attach a Strato TTL receiver to the flash.

          Yes you could use FEC adjustment with the Strato TTL.

    I want to run a combination of profoto B1 or Profoto Acute B2 with Mitros+. Will the Odin Transmitter trigger both the Mitros and Profoto units assuming the Profotos have an Odin Transceiver attached?

      Hi Garl,

      Yes that should be fine, as long as you have a receiver attached to the Profoto’s via sync cord.

      You don’t even need the Odin receivers, you could use an inexpensive Phottix Strato II, or an Atlas II for greater range.

      That is just a basic fire signal though. There would be no TTL or remote power control adjustment of the B1 with the Odin transmitter. You would need Profoto’s own dedicated Air transmitter for that. Thanks.

    I’m sure you are aware, Phottix released a new Mitros+ firmware for the Canon model. v1.06F is now posted and available for download. There are several bug fixes, or improvements in the release.

    Did you receive your Mitros+ yet for a test drive and thoughts?

      Hi Todd,

      Thanks, sorry yes I’ve had the Mitros+ here for a week or so now. The Odin TX interface is excellent, much faster than the Odin TCU itself.

      There is indeed no pre-flash in remote manual with the Mitros+ (as discussed here).

      Thanks yes I saw the new firmware version… EDIT – My Mitros+ came with the firmware update installed already!

      On quick tests I’m not seeing any great issues with fast bursts in manual or TTL (around 1/4 power equivalent) provided an external battery pack is used. I will run through and compare with the 600EX-RT to get a better perspective on where exactly the Mitros+ is at in comparison.

    I literally just got this flash yesterday. Took a few test shots. Simply amazing. After playing with it i sat down to read the manual. i checked the firmware and its the latest, 1.06f, but the hardware version is 1.0.1. This means that i won’t be able to update in the future without borrowing someones windows pc.

    Should i be worried about this and exchange it for hopefully a hardware version 1.04 or later?

      Hi Ahmed,

      I just received the Mitros+ for Canon a week or so ago myself direct from Phottix, and that is hardware version 1.01 as well (firmware 1.06f).

      So I doubt there are any later versions of the Mitros+ for Canon at this stage.

      I think Phottix have likely just accidentally copied and pasted the Mac warning from the Mitros (classic) to the Mitros+ page without updating the hardware versions.

      So I’m not sure what the Mac situation is going to be, but I’m pretty sure you would have the current version Mitros+ hardware, and I would expect any firmware updater would be compatible with that and Mac.

    Hello there,
    any infos about a MItros+ flash and Odin System for the new flash shoe for Sony Users?? I just bought the original Mitros onw as there is no + Version around??

    We Sony users are always one step behind with third party suppliers, haha.
    I have a SOny A7 and A7R mirrorless camera System for my new Event jobs coming up. And the SOny Mitros even has the old Minolta shoe build in ??? So I need an adapter for that to use it on the new multishoe from sony!!

      Hi Andy,

      I’m not sure about that one. You could try contacting Phottix and see if they provide any insights at all. I would dare say the they had the Minolta shoe in development way back before Sony started to make the switch to the new shoe. I would guess Phottix are just keeping consistent with the Odin transmitter and receiver at this stage. But obviously they are all going to need updating sooner or later.

      The Sony Mitros was only just released, so the Mitros+ version may be a while away yet. I don’t think Phottix could provide a time frame, as it just depends on how long it takes to get them functioning correctly with the Sony TTL system. Thanks.

    Has anyone noticed any improvement with the recycle time on the Canon Mitros+
    since the recent firmware update? I’m anxious to test it myself as My prior experience
    was not good with the thermal protection kicking in too quickly. This used to make a
    Portrait session agonizing! Just curious and hope to hear some feedback.


    • Author
      Flash Havoc 7 years ago

      Hi Saul G,

      Yes I have been doing a lot of testing with this. I can only compare the current Mitros+ with the Mitros original though, as I didn’t have the + version with the early firmware to test in detail.

      You may want to grab a seat and some popcorn (and this is only a condensed version of the story).

      So yes Phottix have definitely improved the recycle times, and the number of shots before heat protection cuts in. Recycle times are fast and consistent now, all the way up until the protection cuts in.

      Short bursts at low power and fast frames per second also appear to be ok now, with or without an external battery pack.


      I did a lot of comparisons with the 600EX-RT as well to try and get some perspective on how the Mitros+ compares in this regard. And I think its almost fair to say the Canon flash can do around twice as many shots before heat protection cuts in.

      The reason I say “almost” is because the Mitros slows recycle times down gradually, instead of just hitting a straight out heat protection mode with 8 second recycle delay as the Canon flash does.

      Also I haven’t even gotten to the stage of trying to work out what sort of time interval would basically restart the count before the heat protection cuts in. The Mitros+ may have a shorter reset period. But I could be here forever trying to document how the Mitros+ is reacting, where as the 600EX-RT is very predictable and easy to see how its operating.

      The Mitros+ now also accounts for the flash zoom setting. As a wider setting closer to 24mm puts the flash tube right up against the front lens or diffuser, where it overheats quicker, and can also melt the lens quicker. Canon does account for the zoom setting sometimes as well.

      So the Mitros+ at 1/1 power –

      24mm zoom, 16 shots before recycle is slowed to around 5 seconds.
      50mm zoom, 20 – 22 then 5 second recycle.
      105mm zom, 20 – 22 then 5 second recycle.

      600EX-RT at 1/1 power –

      24mm zoom, 45 shots before heat protection mode cuts in with 8 second recycle.
      50mm zoom, 50 shots, then 8 second recycle.
      105mm zom, 50 shots, then 8 second recycle.


      Mitros+ 1/2 Power –

      24mm zoom, 22 shots, then 4 second recycle for 12 shots, then 5-6 second recycle.
      50mm zoom, 22 shots, then 3 second recycle for 12 shots, then 4-6 second recycle.
      105mm zom, 30 shots, then 5-6 second recycle.

      600EX-RT 1/2 Power –

      24mm zoom, 120 shots, then 6 second recycle.
      50mm zoom, (not documented as 120 above is already well ahead of the Mitros+).
      105mm zom, (as above).


      Mitros+ 1/4 Power –

      24mm zoom, 30 – 60 shots, then 2 – 6 second recycle.

      600EX-RT 1/4 Power –

      24mm soom, 240 shots, then 8 second recycle


      I need to test the Mitros+ 1/4 power times further, as 60 shots is not completely a clear indication. The flash will do a lot more than 60 shots without being slowed, but it needs at least one break of more then the 2 second pop intervals I’m testing at. The results are different all the time, after 30 to 60 shots the flash may slow to 5 seconds, though speed up to around 2 seconds again after a few shots.

      This is the problem with the Mitros+, its still very hard to nail down the complex and inconsistent methods being used to determine the slow down, while the Canon 600EX-RT is completely straight forward.

      So although the numbers above look to dramatically favor the Canon 600EX-RT, they are not completely a fair indication of what the difference is like in real use. Unless you are really going to be shooting continuously at 2 second intervals without any short breaks at all.


      When the latest firmware arrived for the original Canon version Mitros (not the +), Phottix mentioned an update to help stop the front lens from melting at 24mm zoom and full power.

      So I updated the firmware and naturally assumed they would have cut back the number of pops before slow down cut in at full power. But instead Phottix actually increased that from 10 pops to 30 pops when using an external battery pack.

      And by pop 25, at around 2 second intervals 1/1 power, and 50mm zoom (not even 24mm), I heard the flash head “crack” and the front lense was all steamed up and melted! (so its no wonder the Mitros+ is currently limited to 22 pops).

      In comparison the Canon 600EX-RT will do 50 shots every time at the same settings before heat protection slow down cuts in. So that is at least twice as many shots as the Mitros+ before any possible lens damage with the 600EX-RT.

      Though again that is still probably not a completely fair indication for real world use, unless you are actually shooting at full power continuously (which is really not ideal to be doing anyway).

      Also to put this into perspective, I’ve had very few comments about the recycle time / heat protections issues, even from people using the original Mitros and original firmware. Which when put to the test like this would do half the number of pops as the current firmware without some sort of slow down (resulting in very unpredictable recycle times).

      So in real world use this is still likely not going to be an issue for most people. Though to summarize, I think its pretty clear the flashes lens is likely the current limiting factor in the Mitros+. And if you’re not happy with Canon / Nikon speedlites heat protection limitations, then the Mitros+ is certainly not going to be any improvement in that regard at this stage.

      Other than that (and the external battery cord adapter not being ideal) the Mitros+ and Odin system are excellent, solid and reliable off camera TTL. The Mitros+ interface is not as fancy as Canon’s, but its arguably quicker and easier to control a number of remote flashes. With the separate receivers available the Phottix system has a lot of advantages over the Canon system, and for less dollars.

      In reply to Saul G though, the Mitros and Mitros+ are definitely improved now. Though I can’t say if the improvement will be enough for someone like yourself who found the previous version considerably limited.

      If you do get to try the new firmware let us know what you think. And it would be interesting to hear how others are finding this as well.

      For others reading this by the way, I’m really not trying to play down any issue with the Mitros+. At the lower power levels it will fire away a lot more than the numbers above make it appear.

      It’s a very frustrating flash to try and test like this and document results, as it doesn’t follow a uniform pattern (once any slowing starts). Though in real use where you aren’t firing away at constant short fixed intervals, the Mitros will keep firing a lot and pretty fast. I’m not sure how I could quantify / document that better though.

  19. Bill 7 years ago

    I’m thinking about getting another Mitros+ but I’m concerned about future repairs. Does Phottix repair their products, what is the turn-around time and typical repair costs for flash and Odin tx. Are there any 3rd parties that repair Phottix products?


    • Author
      Flash Havoc 7 years ago

      Hi Bill,

      I think the local distributor generally looks after this, so it may vary in different locations. You’d be best to check with Phottix directly.

      In general Phottix have been pretty fast go replace any faulty Odin units etc that I have been aware of.

  20. Bill 7 years ago

    The local distributor is BHPhoto who were no help at all. They had no info on repairs and referred me to Phottix who continue to ignore my emails when I tell them I can’t open the links to the case#. The link offers no option to dl software to open them. Apparently Phottix does not want to put forth the effort to correspond via email instead of their 3rd party link?

    I just read another post on Flash Havoc where Yonghuo won’t answer inquiries either.

    It’s a really no-so-nice feeling spending $500 on Phottix gear and have them treat their customers this way.

      Hi Bill,

      I think are the US distributors. B&H are just retailing them as far as I know.

      I’m not familar what you’re referring to with the links to the case#, download software, or 3rd party link.

      I can get Phottix to contact you quite easily though. Do you have any reference to the enquiry etc I can refer them to? Thanks.

      • Bill 7 years ago

        I have since heard back from BH and they also said are the distributors. The Phottix reference #’s (case #) are all expired. What they do is email you saying an answer to your question has been posted at the site that the link takes you too. It’s as if the responses are computer-generated “do-not-reply” if you know what I mean.

        I will give OmegaBrandess a call or email them. Thanks anyways, for your offer.

        Great blog and site you have here Andy. Thank you again.

            Phottix Support”

            Still having the same problem!…….. SO ANY WEIGHT YOU CAN ADD to the argument would be appreciated

  21. Andrew 7 years ago

    First up let me say I am a Phottix fanboy. I use Odin trigger system with 2 X 580 Exii’s , and a 430 ex and love it. I also have some light modifiers from Phottix. Great Gear.
    HOWEVER after using the Miros + for about two months ( no physical issues with reliability or misfires ) I decided to test the Flash out put with a light Meter, and to compare to the Canons, as some of the results I was getting seemed inconsistent. I had read some reports that the guide numbers ( power) was a little under the 580 EXii but that did not worry me. Repeatability and predictability is what matters.


    Using a Sekonic 308 s Flashmeter Set up was a very dimly lit room, with Sekonic positioned 3 meters (10′) away from flash, and at exactly the same level. Triggering was via a Odin TCU using 1/1, 1/2 and 1/4 power levels only to start with, and using 1/60 Shutter Speed. Lumisphere dome was on the Sekonic, which was pointed at the Flash and mounted on a light stand. Flashes in Manual Mode as no camera used.

    What I found was the Canon numbers were about 2/3 – 1/1 stop overstated which was not a surprise and maybe something to do with their age (?). The differences across the power range changes however were/are consistent with what they should have been.

    That is ….my reading for full power at 50mm zoom @ 3mtrs was 9, and at 1/2 power it was 6.3 and at 1/4 power 4.5 and so on ( ie halving the power did and should require the aperture to open up exactly 1 stop for equivalent EV at same distance)

    So whilst the GN numbers claimed by Canon were a “little” out , the power setting gradations of the Canon flash are exact. ( Note : have since checked my other 580 ex ii and a 430 ex and found the same to be true for both)

    The numbers for the MITROS+ told a slightly DIFFERENT story.

    Firstly and unlike some other reports , the “full power” result for the Mitros+ was exactly the same as that of the 580 exii indicating the same GN at least at that setting.

    HOWEVER the listing below shows the Aperture results from the SEKONIC 308S across the power range setting of the MITROS+.

    Full Power : 9
    1/2 Power : 8 ( 1/3 stop increase in aperture )
    1/4 Power : 7.1 (1/3 Stop increase)
    1/8 Power : 4.5 (1 1/3 Stop increase)
    1/16 Power: 2.8 (1 1/3 Stop increase)
    1/32 Power: 2.2 (2/3 Stop increase)
    1/64 Power: 1.4 ( 1 Stop increase)
    I checked these results three times as I originally thought something must have been set up incorrectly. Same Results.

    So it seems the MITROS + is a “little” off the mark when it comes to the accuracy /consistency of its manual power setting differences. Getting that right should be a priority , and above that of getting a higher full power rating (GN). What is important for me is knowing when I SELECT A SETTING , SHOOT, CHIMP AND ADJUST, the amount of adjustment is “true to label”. Unfortunately that is not the case with my Mitros+, and from what I can tell through some other forums, I am not alone!.

    Hope this test is of use to people and I have notified Phottix of the issue. Hopefully they can address the problem via firmware updates. If anyone else cares to test their Mitros with a light meter and report the results I would be grateful :-). Please Pass on the results to Phottix as well!

    PS: I have also checked the readings for the full power range of the 580EXii’s and the 430 and can report they are consistent ( ie halving the power means you need to increase/widen aperture 1 Stop

    Hi Andrew,

    Thanks for that. I just did a quick test just using the camera histogram, flash bounced of the ceiling so the result is very even.

    UPDATE- I retested flash on camera in manual, and results were ok, slight variations, but only a little more than the 600EX-RT.

    I just checked the firmware is V1.06. I don’t know if this is related to the latest firmware or not. Its probably not since the original Mitros that I have checked the on-camera manual levels in detail.

    I think the levels as an Odin receiver were improved with the firmware update. Which firmware do you have?

  23. Andrew 7 years ago

    Thanks for the reply.

    That is strange and even more worrying if the settings between individual units is not even consistent!!
    It may be something to do with the fact that you did not use an incident light meter to test but your cameras in built reflective meter? Not saying your results are wrong but the setup introduces more variables into the experiment.

    I would be really interested to see other results with the same/similar setup as I used with a light meter, preferably a sekonic. That way all other variables are eliminated and even better if a “control” is also tested using the same light meter and a Canon flash similar to the tests I performed.

    Firmware is the same as yours @ 1.06 for the Mitros+ and 1.23 for the Odin system. All up to date

    Again ..Thanks for the reply…..the mystery continues

    • Andrew 7 years ago

      Apologies the Odin Firmware Version is 1.24 not 1.23 as mentioned above…. I just rechecked ……memory fade:-)

      • Author
        Flash Havoc 7 years ago

        Hi Andrew,

        Thanks, but I knew I should have asked this first… are you actually using the Odin to control the Mitros+ in manual power levels?

        In that case this is nothing unusual, its been a bit of a battle with many systems which use TTL provide pseudo manual flash levels. This is also what the firmware updates have been working to provide. And no doubt they will be tweaked more with future firmware.

        I was looking at the direct manual power levels as set on the flash, flash on the camera. They should be very even, but 1/3 of a stop instead of a full stop is quite a discrepancy!


        Also regarding a light meter, you actually need to be more careful with those, because its very easy to change the results a few tenths just by moving the position of the meter or the flash a little. Because the flash beam is often not that even.

        If you bounce the flash off the ceiling, with everything in the same position between shots, its a much safer guide to the difference in power levels. Not to say your tests don’t sound fine there. Its just that as soon as people start testing things with light meters they often don’t realise the big picture, that the meter is only testing one tiny are.

        And if you really want to get accurate, you have to start taking an average of a number of shots, because as will see they vary from shot to shot as well.

        • Andrew 7 years ago

          Thanks Again.

          Correct … using the Odin to set and trigger the mitros which is set in Odin Rx Mode. The mode of the mitros via the Odin TCU is Manual

          I will test again BUT if that was the issue why would the Canon Flash Units function correctly when triggered via the Odin in the same way. That would infer that the Handshake between the Odin and the Canon units is OK but that between the ODIN and The MITROS is not.

          I will now test the Mitros without the Odin and trigger via the test button AND THEN test on top of a 5D3 using the camera to trigger via shoe.

          Will revert when done!

          • Author
            Flash Havoc 7 years ago

            Yes the results with the Canon flash have been more even, as you say the issue is with the Mitros+.

            We even had discrepancy between the original Mitros (on Odin RX) and Mitros+.

            That last firmware appeared to improve this reasonably well, though I haven’t tested this all in great detail.

            It wasn’t actually until the Odins were available the we even realised YongNuo and Pixel etc have the same issues, they have also been through numerous firmware updates.

            But as you mention its mainly the Mitros flashes now, not so much the Odin.

            • Andrew 7 years ago

              Thanks again for the reply,

              I have been busy testing some more as you will see in my following posts.

              It looks to me like the ODIN TX and RX units in the MITROS+ ain’t the same ODINs as the standalone Variants.

              Alternatively something on the inside of the Mitros+ is interfering with its function!

              Either way ……..”Phottix….you have Problem!”

          • Andrew 7 years ago

            OK TEAM,

            Here are the results of the last test WITHOUT using the ODIN to control the triggering or the manual settings. Sekonic 308 -s flash meter in Incident Metering mode set for Flash metering

            Using the test button of the Flash
            Full : 9
            1/2 : 6.3
            1/4: 4.5
            1/8: 3.2
            1/16 : 2.2
            1/32: 1.4
            1/64; 1.0
            1/128: 0.7

            Perfect differences of 1 full stop per halving of power!

            Using Camera/ Hot shoe to trigger AND TO CHANGE THE FLASH SETTINGS via the Camera menu system

            Full : 9
            1/2 : 7.1……..2/3
            1/4: 4.5…….1 1/3
            1/8: 3.2
            1/16 : 2.2
            1/32: 1.6
            1/64; 1.1……..1 1/3
            1/128: 0.7

            Almost perfect but for a couple of aberations!
            So what does all this mean?

            Observation 1)
            My initial tests using the Odin as the controller showed a perfect change sequence for the Canon Flashes but not the Mitros+.
            Initial conclusion was that the Mitros+ setting differences were incorrect, (?)

            Observation 2)
            Omitting the Odin gave a perfect change sequence for the Mitros + showing that the “internal” change settings for the Mitros+ are in fact correct.

            New hypothesis is that the TTL communications between the Phottix Odin and the Phottix Mitros + as an ODIN RX are not quite working as they should . The fact that the communications/control between the 580 EXii/ 430 ex units and the Odin do appear to be functioning correctly ( initial test results) I can only conclude that the Mitros+ receiving side of the TTL handshake is at fault (?)

            Does anyone disagree and If there are any other results or tests please give me your suggestions.

            Perhaps now I should test the Mitros+ as an ODIN TX controlling a 580 exii to ascertain whether the TTL control of the Mitros + AS A TRANSMITTER works properly.

            I will be Back!

            • Andrew 7 years ago


              Tested using 580 exii ( ETTL Mode) controlled by a Mitros + in ODIN TX mode. Mitros triggered and set manual levels on 580EXii’s. Incident Light Meter levels registered via Sekonic L-308 Flash Meter set to 1/60 Shutter Speed, ISO 100 and set to Flash Meter


              Full : 10
              1/2 : 5.0……..1 1/2 Stops
              1/4: 4.5……….1 Stop
              1/8: 3.2 ………2/3 Stop
              1/16: 2.2 ……..2/3 Stop
              1/32: 1.6 ………1 Stop
              1/64; 1.1……..1 Stop
              128: 0.7 ……….1 1/3 Stops

              Somewhat less than perfect.

              Given the 580EXii gives a perfect sequence when triggered and Set manually AND when triggered and set by the stand alone ODIN TCU it would appear that the in built MITROS ODIN TX is the problem along with its ODIN RX . I cannot test its Strato capabilities as I don’t have any strato receivers but I think they are Manual only (?).

              SO WHAT DOES ALL THIS SAY…… Well the extra money you pay for the Mitros+ is paid on the basis of a promise that it makes to deliver full ETTL RADIO control over your Canon ETTL Flashes in the same way its stand alone Odin system does. It promises that as a receiver and as a transmitter.

              Based on the results of the tests outlined it does not deliver on any of those important promises. Its a good but expensive manual flash and manual trigger system but that is not “the Promise” that I bought. IT HAS A WAY TO GO YET !

              Hopefully this can be rectified through firmware but I am not holding my breathe. As I said earlier I am a Phottix supporter but WOULD NOT RECOMMEND THE MITROS+ for anything other than as a more expensive alternative to the Mitros/Other Manual Flashes.

              PS :

              I don’t feel motivated to test the optical MASTER/SLAVE TTL control at this point but I will I am sure. That said I am hardly confident the results will please me!

          Thank You

          Your Points are well made, and I agree,

          I should have added the following.

          The Sekonic was set to measure results in 1/3 stops ( same as 5D3) and not the default 1/10s.

          I took 3-4 readings per power setting, and then repeated the entire test again with 3-4 readings per setting.
          The Flash was mounted on a Tripod and the Flash Meter strapped to a Light Stand.
          The height of the Light meter Lumisphere was set to be centre of the Flash head, before the 3 meter distance was set using a tape measure on the floor.

          Ambient light was kept consistently very low, so low that I needed a torch to read the meter after a test firing.

          I acknowledge the point about the flash beam unevenness, but the zoom was kept consistent at 50mm, and the positions of flash relative to meter kept constant. I wasn’t so much interested in the absolute reading but the consistency of change as you appreciate.

            Hi Andrew,

            I went through and retested this more accurately, and the flash on camera results were ok, a little more uneven than the 600EX-RT, but pretty similar.

            I can confirm some of what you are seeing with the Odin as transmitter to the Mitros+ though. But its only really from 1/2 to full power that there is only a 1/3rd stop change. I don’t see that from 1/2 down to 1/4 as you mention.

            I think you really need to set your meter to 1/10th stops though to see what the real damage is, because 1/3rd stops can be hiding a fair amount either way.

            The Mitros+ results are not as even as the 600EX-RT/Odin RX, though I get within 1/3rds stop, other than from 1/2 to full power.

            So from what I’m seeing its still a little rough, but hardly a write off, or even a big issue. It was much more noticeable than that before, and hardly anyone mentioned noticing it then.

            You’d be best to do the Odin TX and Mitros+ as RX again in 1/10th stops, and send those results to Phottix. I’d be interested to see if it matches up a little more like what I’m seeing. I’ll get a meter on these as well.

            • Andrew 7 years ago

              Thanks Again for your help

              As suggested see below results using 1/10th stop increments.


              Group 1 : Mitros+ Internal RX controlled by Odin TCU
              Group 2: Mitros+ mounted on External Odin RX controlled by Odin TCU
              Group 3: Mitros + in manual mode triggered manually.

              Each group has three columns which right to left as follows…Full Stop Reading…10ths……Stop Difference from reading above. Example :1/2 Power reading for group 1 is 8.0 and 2/10ths which is 2 10ths difference from the Full Power Reading

              GROUP 1 GROUP 2 GROUP3

              FULL 8.0 4 8.0 5 8.0 5
              1/2 8.0 2 0.2 8.0 3 0.2 5.6 6 0.9
              1/4 5.6 6 0.6 5.6 7 0.6 4.0 5 1.1
              1/8 4.0 4 1.2 4.0 4 1.3 2.8 5 1.0
              1/16 2.8 2 1.2 2.8 2 1.2 2.0 6 0.9
              1/32 2.0 6 0.6 2.0 6 0.6 1.4 5 1.1
              1/64 1.4 4 1.2 1.4 7 0.9 1.0 6 0.9
              1/128 1.0 6 0.8 1.4 0 0.7 0.7 6 1.0

              Stop RANGE 5.8 5.5 6.9

              As you predicted it changes things a little. The interesting thing for me is the fact that using the ODIN RX whether internal or external render the essentially same results when coupled with the TCU. More interesting is the fact that compared to manual Full Stop in Total Power Range is lost when using the Mitros TTL handshake to change settings, and it is lost from the bottom (1/128) end.
              (See the Total Range of ~5.8 stops V 6.9 Stops from Full to 1/128)

              Like you said its not a train crash, but it is not good. Looking past the inconsistency of stop change: Pwr Change, when using ODIN radio triggering and ttl to change settings while using Manual Flash you just need to remember the following as a rough rule of thumb :

              “Other than for Full Power, the power setting indication is 1 full stop understated”. See below

              Pwr set Actual Output

              Full FULL
              1/2 FULL
              1/4 1/2
              1/8 1/4
              1/16 1/8
              1/32 1/16
              1/64 1/32
              1/128 1/64

              In manual the Mitros power setting: Actual Output is “true to label”

                  Apologies again ………………..Last Group in list is actually Group 3……….. I’ve been doing to many tests:-) and going slightly mad I suspect!

  24. Andrew 7 years ago

    Hi …….Again,

    I have taken your advice again and rerun all tests using 1/10ths.

    I have now completed a complete suite of side by side tests of Canon 580 Exii V Mitros+ tests using a light meter. The primary purpose was to examine the consistency of function particularly with respect to indicated Power Setting and Actual Output levels across the power range and across differing Flash control methods.

    Tests of Mitros +
    a) Controlled and triggered by external Odin TCU using internal Odin RX
    b) Controlled and triggered by external Odin TCU using External Odin RX
    c) Controlled and triggered by Camera hotshoe and Menus
    d) Controlled and triggered Manually

    Results for c & d identical

    Tests of CANON 580EXII
    a) Controlled and triggered by external Odin TCU using External Odin RX
    b) Controlled and triggered by a Mitros+ internal Odin TX using External Odin RX
    c) Controlled and triggered by Camera hotshoe and Menus
    d) Controlled and triggered Manually

    Again Results for c & d identical

    I will not try to post all the results here, as I have learnt that trying to post tabulated results here just does not work. I have however emailed Flash Havoc via the Contact us system and offered to send the files containing the detailed results . They are interesting I think and show the following:

    Canon Flash 580 EX iis consistently deliver results in line with expectation whereby Test results consistently show a 1 stop change in aperture (+/- 1/10th stop) for every halving/doubling of power (all other factors constant). They do this regardless of whether they are controlled or triggered by

    a) EXTERNAL Odin TCU and Receiver
    b) Mitros + internal Odin TX and external Odin Receiver
    c) Camera Hotshoe and Menus
    d) Manually

    The Total Stop Range across the full power range from Full to 1/128 is between 6.9 and 7.1 stops or 7.0 Stops +/- 1/10th

    Phottix MITROS+ Flash units consistently deliver results in line with expectation whereby Test results consistently show a 1 stop change in aperture (+/- 1/10th stop) for every halving/doubling of power (all other factors constant) ONLY when the Flash is controlled and triggered as follows:

    a) Manually
    b) Camera Hotshoe and Menus

    The Total Stop Range across the full power range from Full to 1/128 is 6.9 stops

    When the Phottix Mitros+ is used with either external Odin TX/RX , Internal RX/TX or a mixture of both the results delivered are variable, non linear and inconsistent. A halving of power via the settings will produce an actual output which calls for a change in aperture between 0.6 and 1.2 stops. Additionally changing the power setting from Full to 1/2 registers a reading of only 0.2 stops .

    As a consequence the Total Stop Range across the power range for these two control/trigger methods is between 5.5 stops ( external RX) and 5.8 stops (internal RX).
    The ruff cut adjustment you need to make if using with ttl control and manual settings via the TX/TCU is to see setting of 1/4 power as 1/2 power in reality , a setting of 1/8 power as 1/4 power in reality etc. You would also see settings of 1/1 and 1/2 as essentially the same at full power.

    As the moderator stated it is not a train wreck….But its not that good either considering the Mitros is not exactly cheap.

    Lets Just hope they CAN FIX VIA FIRMWARE and not release a Mkii. I am not sure I would “stump up” for another Mitros+ after the first experience if the Mki is not fixed!



    A) Stand alone Odin trigger system works consistently with Canon flashes
    B) Mitros+ internal TX system works well with external Odin Receivers and Canon Flash Units
    C) Mitros+ works consistently when controlled/triggered Manually
    D) Mitros+ works consistently when controlled/triggered by camera hotshoe and menus.


    E) Mitros + internal TTL control system works inconsistently with external Odin TCU regardless of whether it is using internal or external Odin RX units.

    It is becoming clear ,I think (?) , that the problem is within the internal Odin TX/RX interplay and/or the interplay between the internal RX and External TCU. That said the problem is within the Mitros+ and not the external ODIN TCU as the system works flawlessly when coupled to canon units.

    What would be good is whether someone with two Mitros+ units could test using a light meter and a similar methodology to the one I used…Any takers?

    As mentioned happy to send the detailed test results and setup details to anyone who is interested , and I have emailed Flash Havoc via the Contacts page to give me an email address/ site to send/upload the result details.

    I have also sent the details to Phottix but who knows where the Support Ticket system will send that?!

    PS I am all tested out! :-{ but at least its done! .Apologies in advance for typos etc as I am sure there are a few that I have missed.

    Hopefully this Link to the pdf file detailing the results will work

  26. Jyri Seppälä 7 years ago


    what do you think, which one would be better. 580ex II + Odin system or Mitros+? I’m looking at 2 flashguns and then later adding the indra500 ttl strobe.

    I’m kinda worried about the inconsistant TTL… Thanks for the replies.

      Flash Havoc 7 years ago

      Hi Jyri,

      I don’t think there is any great issue with inconsistent TTL with the Canon version Mitros+. Nikon owners have some TTL complaints though.

      The main issues with the Mitros and Mitros+ that I’m aware of have revolved around the recycle speed and overheat protection. Unless Phottix have upgraded the front lense on the flashes (so they won’t melt), the Mitros+ will basically only do half the equivalent amount of flashes as the Canon flash before slowing for overheat issues.

      So if you work the flashes hard and fast, then yes you would be better off with the 580EX II or 600EX-RT and an Odin receiver. You can’t really use the Canon flash as a master on the camera with the Odin system though.

    • Andrew 7 years ago

      Hi Jyri,

      Based on lots of tests I have done on the Mitros+ for Canon, you would be better to go with Odin system with a couple of 580 EX ii’s OR even a couple of plain vanilla Mitros ( not +’s) units, first up .

      Yes there are some minor but inaccuracies with the Mitros+ radio TTL system….but nothing that can’t be compensated for….but annoying!.

      see for a better summary of those tests, if you have not seen already.

      The ODIN SYSTEM IS AWESOME….but the Mitros+ has a way to go yet to emulate the perfect performance of the independent Odin system…..Maybe think about a Mitros + after the next firmware update.

      FH is right about not being able to use the Canon Flash as an on camera master in conjunction with the Odins however.

  27. Todd 7 years ago

    Phottix users:

    Phottix just released a new firmware for the Mitros+ for Canon, V1.07

    Firmware v1.07 for Phottix Mitros+ for Canon flashes is available for download. It optimizes the following:

    1. Improved the overheat protection issue of flash head.

    2. Improved the battery issue.

  28. David Tucker 7 years ago

    Just a heads up for the Mitros + if you’re using an external power supply. You must turn on the flash first, then the external power supply otherwise the connection will not work, and you’ll just be using the AA batteries not the power pack. Also, even though you’re using an external power pack, the Mitros+ seems to eat batteries very quickly.

  29. keano 7 years ago

    Hi guys can I ask in your opinion if anyone has used the Phottix and Yongnuo systems and is the Yongnuo pretty stable?

    Is the Yongnuo set up (568ex, 622N, 622N-TXi) for radio triggering off camera TTL more stable then the Phottix system? Including exposure etc.

    • Author
      Flash Havoc 7 years ago

      Hi keano,

      The Phottix Odin have been one of the most stable and reliable radio TTL systems available for a number of years now. The range is no better than the YN-622C (actually it is better than the YN-622C-TX) but they have never really suffered from the little meltdowns other TTL triggers experience (usually just needing a quick reboot). The YN-622 system is mostly fairly stable though.

      Though look, I saw your post on Dpreview about deciding between the V860N, Witstro AD360, and Rovelight etc.

      There is a wild variation between those lights from one extreme to the other, and the thing is no one is really going to be able to tell you which you’re going to prefer using (if you do even use just one system). I know its not easy, but the only way you’re going to know is through experience with them.

      With that in mind I would seriously consider the StreakLight AD360 deal while its available. Worst case scenario, once the deal is over you could likely sell the light again for most of what you paid for it you didn’t like it.

      That’s a middle of the road light though, its not low power like a speedlite, and its not big to carry like a studio light or Rovelight etc. So its likely the best place to start and get a feel for what you need in any case.

      Then to complement that with a flash that can be used on camera with ITTL, you may as well go with the V860N. Add a $15 FTR-16s receiver and you have a second off camera light when needed. Both with remote power control from the camera. Simple reliable manual triggering with 100m range.

      If it wasn’t for the TTL I’d take the V850 over the V860 any day for off camera use, simply because the sound beep tells you when power levels have been changed from the transmitter. But as an on camera flash as well the V860 are is still a great combination.

      Then when you want to experiment with HSS you could get a set of YN-622N. Place the Godox FT-16 transmitter on top of one of those on the camera and you have HSS with the Witstro. A YN-622N receiver on the V860N and you have HSS with that as well.

      I’m not saying this is sweet integration like the Odin / Indra / Mitros+, but its about the best bang for buck your going to get on a budget otherwise, considering the current StreakLight deals. This system should expand as Godox adds more TTL units later as well though.

      If the Rovelight were still on special for $399 with the Bowen’s mount I would seriously be considering those as well. But to me they would be a much bigger risk as to whether they are going to be practical to you or not, as they are big heavy lights compared to the Witstro (let alone speedlites). At that price they were ridiculous bang for buck for what they are good at though.

      • Keano 6 years ago

        Hi Flash Havoc,

        I actually followed your advice and have a Streetlight 360 and 850. The battery life is amazing. They give out a colder color then the Yongnuo 568ex I have. I should of stopped there. LOL.

        The v860N didn’t work out at the time underexposing. So I tried the 568ex which works quite well. So I bought a Indra500 and did a number of tests. The TTL works quite well and the HSS. Not cheap though. I added a Mitros+ to try out because of the Odin system and compatibility. I don’t see a huge difference between the budget 568ex and Mitros+. So I feel overwhelmed. Photo isn’t cheap. Other option is return the Mitros+ and Indra and get 2 Einsteins. for TTL stick with the Yongnuo 568ex.

      Also the V850 / V860 batteries appear to be holding up well again now, so these flashes are going from almost off the radar completely to back near the top of my favorites.

      The Witstro batteries appear to be holding up well now as well. They are both available from Adorama with 12 months warranty, so its not a big risk now in any case. (V860N are the Flashpoint Zoom Li-on at Adorama).

  30. Ahmed A. 6 years ago

    I have been on the fence about staying with the Phottix Mitros+ or moving to the Yongnuo YN600EX-RT. Welp, Phottix just made the decision for me. I have a Mitros+ that has less than 300 pops on it, that just died. It won’t power on. Sent it in for warranty repair. Its still under warranty, but the specific problem is not covered and the the bill is $100. Never again will i invest in flashes that cost more than Yongnuo’s.

      Hi Ahmed,

      Something doesn’t sound right there. What was the issue with your flash that is not covered by warranty? Thanks.

      • Ahmed A. 6 years ago

        Last week it worked. This week I turn it on and nothing. So I thought the batteries were dead. I Replaced the batteries and nothing. So I contacted phottix and they referred me to their US repair facility MacGroup. I send them them the flash and my receipt, a few days later I get an email saying that the battery compartment needs to be replaced and that it is an out of warranty repair. $80 plus $15 shipping.

        I’m confused because I could have sworn that the warranty was 2 years. So I dig out the box, find the warranty card and just as a thought, it says 2 years. I still have a whole year left so I tell them that. They reply with the battery compartment is not covered.

        At this point I can either pay to get it repaired or have them send it back for $15 and have an expensive paperweight.

          Thanks Ahmed,

          They battery compartment doesn’t need replacement because batteries have leaked inside causing corrosion on the contacts does it?

          If that was the case I could understand that would not be covered under warranty. Or if they are just saying the contacts are corroded. If not I can try and contact Phottix for you to see if they can resolve this better.

          • Ahmed A. 6 years ago

            none of the batteries i use have leaked. i only use eneloop pros and there was nothing wrong with the set i took out. they work perfectly fine in a pixel flash. macgroup is saying that the reason that the flash doesn’t power on is because the battery compartment is corroded.

            I’ll email phottix again and see what they say.

          • Ahmed Agbabiaka 6 years ago

            Update – the 2nd inquiry to Phottix wen’t unanswered so i had no choice but to pay for the repair. $80 repair, $20 shipping there and $20 to ship back. Out $120 on a product that is still under warranty.

            While the Mitros+ was in the shop, i picked up two slightly used Yongnuo YN600EX-RTs for less than the price i paid for the Mitros+ to get repaired. If they perform even slightly as good as the Mitros+, i’ll cut my losses and sell the Odin and Mitros+. If not, maybe i’ll stick with Phottix for a little while longer.

        • Christer 6 years ago

          I’m sick of the Mitros +. I have 4 of them and all but one has blown a bulb . The funny thing is I also have 4 mitros which has never given me a problem. I sent them in twice because of bulb blowing once again. I had to by a whole new system because of how unreliable they are.. I pick up the 6 V860N/zoom ttl when they went on sale at Adorama. I’m impressed with the v860n. the haven’t let me down yet. I have shot 10 weddings with them so far. Once I get back back the +’s I hope they get fix for the finally time.
