PHOTTIX MITROS+ For NIKON – Now Available!

Phottix Mitros+ flash units for Nikon are now available in the Phottix Store, and should be making their way to other popular retailers soon.

Mitros+ are the first Speedlight system available for Nikon with full ITTL Radio Transceiver built-in. And therefor a major breakthrough for the many Nikon owners who have been waiting for a Nikon compatible alternative to the popular Canon RT radio flash system.

The Mitros+ even have some significant advantages though over the Canon RT system, as you can still combine your existing ITTL flashes in the new Mitros+ radio system by attaching Phottix Odin receivers to them. As well as fire manual studio lights etc (via Strato II, Atlas II, or Odin receivers) without having to add inconvenient extra manual transmitter units to the camera.

And the new Mitros+ flash retails from around $399, making the Phottix system more affordable than the current Canon option, or likely anything Nikon may themselves offer in the future. While still providing what has proven to be one of the most solid and reliable systems available, and with 2 year warranty as standard.


Phottix Mitros Plus For Nikon

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
  • Nikon-compatible Master/Slave IR Triggering Modes
  • ITTL, 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.

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 Mitros + also solves one of the most common problems encountered by many wedding and event photographers currently using the Canon RT Radio flash system. That is how to fire other Canon (or in this case Nikon ITTL flashes) and manual 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 on the camera.


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 etc.


Price and Availability –


The new Mitros + for Nikon is available now from the Phottix Store for $449.99.

They should also be making their way to other retailers soon from around $399 –

    Finally!!! Yeah!

  2. mark 5 years ago

    I’m I understanding this statement correctly, “The Mitros+ even have some significant advantages though over the Canon RT system, as you can still combine your existing ITTL flashes in the new Mitros+ radio system by attaching Phottix Odin receivers to them. As well as fire manual studio lights etc (via Strato II, Atlas II, or Odin receivers) without having to add inconvenient extra manual transmitter units to the camera.”

    Does this mean that if I use a Mitros + on camera with an Odin receiver attached to an off-camera SB 900/910 that I will be able to control both manual and iTTL output from the on-camera Mitros + unit?

    Then with a Strato II I would be able to control manual output of an off camera 900/910 from an on-camrea mounted Mitros +?

      Hi Mark,

      The first question is correct. You have full control from the Mitros+ on camera if using an Odin receiver on Nikon ITTL flashes.

      But the second question is no go. The Strato II receivers are manual only, with no remote control ability. All the Strato II can do is allow flashes (or groups of flashes) to be turned on and off from the transmitter. The Transmitter can be the Mitros+, Odin, or Strato II TX. Thanks.

    I hope this is Great news for Nikonians. Practically this flash will one of the best solution for wedding photographers. Is any chance to only mute the masterflash or off cam flash if we needed?

      Flash Havoc 5 years ago

      Hi Ganesh,

      Yes, if you see the LCD screen image on the back of the flash, there are 4 separate groups, and the top one is for the flash on camera. So you would simply set that group to OFF. Or do the same with any of the off-camera groups.

      You can set any group to TTL, Manual or OFF. Thanks.

      • Ganesh Naravian 5 years ago

        Thank u FH …For quick replay…. In my opinion this flash meet most requirements (TTL,HSS,AF Asist lamp,build quality, easy to mount on camera/stand ,finally price & warranty ) of pro photographers.

  4. Will 5 years ago

    Can you control the power of monolights like the alienbees? (like the pocketwizard system)… the phottix’s system seems super solid…. if only they had this flash with the Li-ion battery I would sell everything.

    • Donald 5 years ago

      ” .. control the power of monolights like the alienbees? .. ”

      No, the Mitros+/Odin system will only trigger (incl ODS timing) monolights. But an increasing proportion of Monolights now come with their own remote power modulating system. So you can vary their power fraction setting remotely, before the shot (TV remote style) – and – then trigger in sync via Mitos+/Odin.

      • Will 5 years ago

        Donald- with the pocketwizard ac3 you can mix off camera flashes and studio strobes on the same transmitter unit. It’s really convenient. I have just been looking like a flash system like the phottix one but without being able to also change the power of a strobe I don’t think it will work with my shooting style.

  5. Thomas Geist 5 years ago

    A big question for me is: how does this system work cross-brand?

    Can I trigger and control a Canon Mitros+ with a Nikon Mitros+ or Nikon Odin? And vice versa?
    Of course TTL and HSS functions are excluded from this – we don’t want to go too far. But power control, groups etc. … ?

    This is one of the few nice functions of PocketWizard’s ControlTL devices. They DO work cross brand. Power control works flawlessly (if it works, he he). This and the ability to fire AND power control Einstein strobes makes me still stick with the PWs.

    P.S. Sorry for cross-posting this, but I thought there might be people who have experience with this either with the Phottix or the YongNuo systems.

    • Ganesh Naravian 5 years ago

      I have same question here. Using canon & Nikon both cameras or switching brands creates unnecessary invest on ttl flash. If cross branding possible in mitros+ it will be more useful for lot of photographers ( atleast manual power adjustment & group ). . If anyone tested pls let us know.

      Flash Havoc 5 years ago

      Hi Thomas and Ganesh,

      As far as I am aware the Canon and Nikon version are completely independent. The Odin for Canon and Nikon for example will not fire each other.

      But now that I think of it, the Mitros+ also have a Strato II receiver built in. So if the slave Mitros+ (Canon or Nikon) were set to Strato II receiver mode, they should actually be fired by either Mitros+ as transmitter.

      No remote control though, at most groups could be turned on and off from the transmitter.

      If not you could use a receiver ( Odin / Strato II / Atlas II ) to simply fire the Canon or Nikon flashes.

      But I think that would be about the extent of it for now, definitely no remote manual control across systems at this stage. Thanks.

      • Ganesh Naravian 5 years ago

        Thank you Flash Havoc……

  6. Dave Cheung 5 years ago

    Thanks for the preview.

    A question for mutliple-shooters triggering the same lights:

    Can two or more transmitters be used to remotely trigger these flashes at DIFFERENT power/iTTL/Manual settings at the same time?

    Thanks in advance for your time!

  7. David C 5 years ago

    Are any companies thinking of licensing their system? I’m not sure if Canon is licensing their RT system or if others like Yongnuo are just reverse engineering them, but it seems like to me that it would be great if someone would license (small fee involved to recoup intellectual capital) the radio control system to others so we could have a choice of different providers working on the same system. I guess this is what the Canon system is either on purpose or by accident. Wish this would occur for Nikon, or across multiple 3rd parties. For instance, if Phottix licensed the ODIN system so Yongnuo could create a Mitros+/ODIN compatible Flash. That would offer real choice. If there was that one “standard”, Studio light companies could start to license and support it as well.

    That way the same compatible system could be used across brands and if that occurred, the only thing that would be brand specific would be the flash or Transmitter that sits on top of the camera itself, communicating with it. By the way, is that true for today’s ODIN system, will a Nikon Mitros+ Flash work as an “off camera” flash in a Canon ODIN system, where you use the Canon ODIN TX on the Canon?

    • Author
      Flash Havoc 5 years ago

      Standards would be nice in an ideal world, but most companies are working hard to make their systems proprietary, so that you have to stay within their system.

      The third party systems are all reverse engineered. I think its highly unlikely Canon would license their systems at all unfortunately, but even if they did you can imagine they would want to make a tidy profit.

      I will need to check, but I think it may actually be possible to have a Canon Mitros+ fire a Nikon Mitros+ if the Canon was set to Odin TX and the Nikon slave Mitros+ was set to Stratto II RX.

      It would only be a basic fire signal though at most. So pretty limited at best.

      If not you could use a receiver ( Odin / Strato II / Atlas II ) to simply fire the Canon or Nikon flashes.

  8. Ulysses 5 years ago

    I remember there were a few complaints about the original Mitros flash unit having problems with overheating, and in fact some users even now issue complaints about this.

    Has Phottix addressed overheating issues with firmware updates for the Mitros? Should we expect that the Mitros+ flash will have similar issues requiring firmware updates to address this?

    • Author
      Flash Havoc 5 years ago

      Hi Ulysses,

      It was not quite an issue of overheating, but the overheat protection slowing the flash recycle prematurely. In which case the flash can’t get anywhere near overheating then.

      From my experience with the recent Mitros Firmware Update, that has certainly improved the recycle, and overheat cut in time dramatically.

      However… testing it side by side with the Canon 600EX-RT, the Mitros will recycle faster than the 600EX-RT, and right up until the heat protection cuts in. But the heat protection cuts in at around 20 to 25 full power pops, as opposed to 50 for the 600EX-RT.

      At half power, protection slow down cuts in at 30 consecutive pops on the Mitros, where the 600EX-RT would do at least 60 pops.

      But that is consecutive shots in a row. I haven’t studied or worked out how long you have to break for in any of those sets to basically start the recount over. So in real use it may take a lot more than 20 shots to reach a slow down.

      The Godox V850 for example only does 20 pops at full power as well, but I know you only have to break for 30 second before the 20th shot to start a recount. So in real use you can shoot a lot more (likely a lot more than the Canon flash which has a 50 consecutive shot cut in).

      I don’t know how the Mitros ticks yet in this respect. But nevertheless I let Phottix know that I think 30 consecutive shots at half power is still not quite right.


      Mitros+ – I assume this has already had some degree of update before being released. I don’t think I have heard any comments about the Mitros+ heat protection, so I would assume its something similar to the recent Mitros firmware update anyway.

      Hopefully Phottix release some form of firmware update for the Mitros+ as well though, so we know for sure that everyone is on the same page then. That has been the biggest confusion with the Mitros, as everyone was previously reporting different findings.

      So as of right now, with straight out consecutive shots, the 600EX-RT are ahead, followed by the SB-910, and then the Mitros. But I’m still not sure that tells the full story, unless that is really how you intend to shoot in real use, without any pause at all.

  9. Thomas Geist 5 years ago

    Dave, it shouldn’t be a problem to have different shooters fire the flashes at different levels.

    From what I understand they are similar to any other remotely controlled TTL flash as they get their power setting merged into the trigger signal. Trigger signal with different level results in flash firing at different power.

    (This is in contrary to the non-TTL systems like a PocketWizard firing an Einstein plus PowerMC2: here setting power is a separate process from firing the flash.)

  10. Dave Cheung 5 years ago

    Thanks Thomas, but I’m particularly interested in Manual Power changes, not TTL.

    Even the PW’s ControlTL manual implementation this is an issue: AC3’s only transmit manual power changes at time of the change, not at time of image capture. For multiple shooters this means the last person to change the setting wins.

    Another way to phrase the question: when is the manual power setting transmitted to the receiver? Is it (a) at time of manual power change or (b) at time of image capture? If (b), it might work for multiple transmitters controlling the same flashes at different power levels.

    Hope this makes sense.

    • Author
      Flash Havoc 5 years ago

      Dave, that’s correct, the Canon and Nikon version Odin send the power level information before every flash.

      So in theory that should work, but I personally have not tired it. My concern would mainly just be that if you happen to fire too closely, or at the same time, that it may cause issues. More than likely just do a full power dump of the flash, hopefully nothing worse.

      I know plenty of people have 2 shooters with Odins, but I’m not sure if they share lights. Hopefully someone with first hand experience can give some feedback on this.

      Thomas – That is true of most Nikon systems, but ones using, or compatible with the Canon Flash Control Menu, like the YN-622C, and Pixel King / King Pro etc, do set the power on the flash independently of the fire signal.

      As soon as you adjust the camera, the settings are sent straight to the flash, well before firing. And they won’t update settings unless you change power level etc again (just firing the shutter won’t update them).

      The Odin for Canon are more like the Nikon version though, sending the signal before each shot.

      • Dave Cheung 5 years ago

        Thanks Flash Havoc!!

        Gives me hope but yes: would LOVE to have real-world multiple-shooter users pipe in on this topic.

        Of course, we’re always available to test the system for Phottix 😉

        Thanks again!

      • Dave Cheung 5 years ago

        A related question: when triggered remotely from an Odin TX at a manual power level, does the Mitros+ pre-flash?

        I believe pre-flash, even when using manual power settings, was a quirk of original Nikon Odin system and am hoping they’ve removed this power-sapping issue with the release of their own flashes.

    • Ulysses 5 years ago

      I asked a Phottix your question, Dave. Here is their reply to me:

      “Answer: Thank you for contacting us. The answer is (a) – in Manual mode the signal is sent in the moment of changing the settings of the Mitros+ flash options. The changes are done for groups – more than one flash can be assigned for a group, and the change will apply to all of the flashes in each particular group. Thank you.”

      Though not the most desirable answer, at worst this would be no different in behavior than what we currently need to do with our PocketWizards with AC3 zone controllers or with Cheetah Lights. But we could still have an overall simpler lighting solution on our hands. So I’m still leaning rather positively towards these flashes.

      I have asked Phottix if this signaling behavior is at all changeable via the flash menu. Even if not, you never know… Maybe a firmware update?

  11. Ulysses 5 years ago

    I’m really enjoying the Q&A session here, with all the great feedback.

    The YongNuo YN-E3-RT with its latest firmware update adds remote manual control for NON Canon cameras! (see more at: ) YES!! Presumably the upcoming YongNuo YN-600EX-RT flash will have the same capability built in.

    This logically leads to my next question:
    Is there any indication that the Phottix Mitros+ speedlights currently or in the future will provide remote manual control for NON Canikon cameras?

    Many pros and enthusiasts are integrating mirrorless cameras into their studio workflow. We’ve been anxiously awaiting solutions for good lighting support for our other gear beyond Canon and Nikon cameras.

      Flash Havoc 5 years ago

      Hi Ulysses,

      The Canon system is a bit different in that it sends the manual power level setting as soon as you change them on the camera or master flash.

      The Odin / Mitros+ for Canon and Nikon are a little different, in that they use the flash in TTL mode and send a power level to the flash before each shot.

      So I don’t think its possible to transfer that same system directly to a non dedicated camera, as the communication has to happen before the camera shutter opens, and it takes a dedicated camera to know about all that and fire the shutter in sync.

      Having said that, now that Phottix have their own flash as transmitter and receiver, I don’t see why they can’t do practically anything know that they have full control of both. They could have a separate remote manual system incorporated just for non dedicated cameras.

      Phottix have been posting a number of mirrorless camera releases on their blog lately. I really don’t know if that may be a hint towards something.

      • Ulysses 5 years ago

        Very, very interesting! Thanks for providing more insight on how this all comes together. I’ll be sure to take a look at the latest Phottix Journal on their site.

        Radio transmission for Nikon has been a long time coming, so I’m eager to check out this system. It seems providing mirrorless solutions will be the next most hoped for logical step as that category of camera use by professionals grows.

  12. Darryl Jones 5 years ago

    If I get the standard Nikon Odin Transmitter and the Mitros+ acting as a receiver. Would this set up support ODS? I know the Mitros + acting as a transmitter does not. But not sure about acting as the receiver?

    • Author
      Flash Havoc 5 years ago

      Hi Darryl,

      As long as you have the Odin TCU as the transmitter, the receivers shouldn’t matter. So you can use the manual Strato II or Atlas II as receivers and still get the early fire signal to the flash unit.

      But this is generally for manual studio lights etc. The Mitros+ as a slave flash already has FP HSS being a TTL flash.

      But I’d say you could set the Mitros+ to the internal Strato II receiver and make it do long duration sync as well. That only works at full power though with a speedlight, so its generally preferred to use the FP HSS as mentioned above (which would be selecting the built in Odin receiver instead).

  13. mark 5 years ago

  15. MRomine 5 years ago

    The Mitros + were incredibly easy to use! Not a single miss fire in about 2.5 hours of shooting inside an antique store. Not much room to shoot, two off camera units were within 15ft or less of the camera the entire time. Softbox on one and grid on the other. Very happy with the outcome and ease of use.

  16. Ulysses 5 years ago

    Reports are gradually rolling in from colleagues, wedding photographers who have received their Mitros+ for Nikon and have been trying them at events or otherwise testing them. The reports are rather mixed, but tell of frustration on the part of wedding and event photographers. The reported problems include underexposures when bouncing the flash vss direct flash, slow recycle speeds, and misfires when shooting sequences (this is probably related to the slow recycle speeds).

    One report says:
    “The flashes were definitely set up correctly. I didn’t have any trouble with that. The instructions were included on a flash drive.

    Most of the time I had two off camera flashes going set on manual. 1/8th for formals. 1/32 for reception. If I was slow in terms of popping off frames it was ok. But, during bouquet toss for instance with the camera set on low speed motor drive… only the frames of the flowers going up in the air are lit. As it went down they were dark.

    During formals… I’d take three shots in a row of a setup. The first one would be lit. The next three dark.

    This would normally be no problem at all for a sb-900.

    I tested the flashes ahead of time… But playing around in your living room and shooting a live event are different animals.”

    Another colleague of mine has been testing them and found:
    SB-800 will fire many in a row at low power. Mitros+ will fire 1 or 2. Tho the exposure of the SB-800 does drop through the sequence, just not badly. The SB-800s are getting tired and wiggly so I wanted to replace them. Mitros+ are nice in the shoe and do nice TTL direct. Bounce is consistently under-exposed. I’m undecided.

    I have encouraged those with problems to submit a support ticket to Phottix with their observations.

    • Author
      Flash Havoc 5 years ago

      Hi Ulysses,

      Thanks for that.

      It sounds like the Nikon Mitros+ still needs some tweaking then, so yes definitely let Phottix know, and hopefully they can get a firmware update together.

      Although I still don’t think the Canon Mitros is quite where it should be, after the latest firmware its clearly much better than you’re experiencing there with regards to recycle time and motor drive.

      As mentioned here to Mitch – 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 the Nikon Mitros+ is quite a way behind there, and they should be able to update that. They should be able to sort out the exposure issue with bounce as well, so yes definitely let Phottix know.

  17. David Tucker 5 years ago

    How does the power compare with the Canon 600. I’ve heard it was 2/3 of a stop less power than Canon, but I’m not sure how reliable that source was.

    U, In regard to underexposing when bouncing, I’ve found that to be a common problem with Canon as well.

    • Author
      Flash Havoc 5 years ago

      Hi David,

      I can’t comment on the Mitros+ just yet, but assuming it would be the same as the Mitros, I found its fairly equal when used direct at the same zoom settings etc. But when bounced at the same settings in general I get 1/2 a stop less with the Mitros (that’s using manual power setting, not a TTL metering issue).

      So the Mitros is putting out a bit less light, its just spreading the light in a slightly different way.

      • David Tucker 5 years ago

        Thanks, yeah sounds like it has a bit wider beam perhaps? Good to know. I suppose you could use the manual zoom to increase your power when bouncing. I used to use a gizmo called the Better Beamer which has a fresnel lens to get more power for those situations where I was bouncing off a far away wall in a big hall. Looks a bit weird but it gave me a couple extra needed stops.

  18. David Tucker 5 years ago

    One of the things that always bugged me about the Canon speedlights was that when working in low light situations it was anyone’s guess if the unit would decide it “needed” the focus beam to come on. Frankly I’ve always wanted the option to be able to choose to have the focus beam come on all the time. Do you know if the Phottix Mitros+ has this option?

    If not that would be a great firmware fix.

    • Author
      Flash Havoc 5 years ago

      Hi David,

      Sorry no I don’t think there is any option to have the AB beam come on all the time. I know what you mean it is annoying sometimes the way it decides for itself.

      I’m not sure this would be simple to implement though, unless it was completely manual.

      I could be wrong, but I think the camera needs to constantly supply the on and off signal to the flash as you half press and shoot etc. So the flash can’t decide when to do that alone, the signals need to actually come from the camera.

  19. Joe Appel 5 years ago

    After testing my Mitros+ for Nikon I found, as others have reported, that the unit just doesn’t keep up when set to the TTL mode.

    This observation holds whether I’m using the Mitros+ as an Odin transmitter and flash, or simply as a straight on-camera flash.

    When set to Manual mode the flash will fire and trigger the Odin receivers without missing any frames. This is great, but certainly limits the usefulness of the system.

    I opened a support ticket with Phottix and at their request provided them with sample images. Phottix’s reply to me was to be sure to allow the unit adequate time to recycle. To their credit, they’ve been attentive to my emails. But I found the answer to be unsatisfactory.

    They asked me to check the firmware version on the flash, which is 1.03. Am I correct in thinking that’s the most current version?

    • Author
      Flash Havoc 5 years ago

      Hi Joe,

      Thanks for the feedback. My Canon version Mitros+ only arrived the other day so I haven’t had a chance to test all this too well yet.

      I actually thought people were saying the issue was in manual as well.

      I don’t think there have been any firmware updates made available yet for the Mitros+. Though its possible they could have shipped with different firmware versions. This is what made it difficult to compare with the original Mitros, until everyone was on the same update.

      If anyone else is having issues, keep letting Phottix know so that they look into this more urgently. Thanks.

      • Joe Appel 5 years ago

        I’ve heard back from Phottix support. They state that the issue will be addressed in a firmware update coming sometime later this month.

        Happily, I received this message on April 4th and not April 1st 😉

          Thanks Joe.

          The Canon version Mitros+ firmware update was posted a few days ago. The Mitros+ I receive last week had the new firmware already installed as well.

          It seems pretty fast, using a battery pack at least. I’ll compare it in more detail with the 600EX-RT to see exactly how it stacks up, but in general it seems pretty fine now. I wouldn’t like to push it any harder than I’ve been able to at full power anyway.

    I just received my 3 sets of mitros+ and odin tcus. I have to say I was excited to receive these after years of using a radiopopper jrx based solution to fire my strobes off camera.

    I unfortunately have a few bugs to report. one Being MAJOR.
    worst first.
    When the mitros+ is used as an off-camera flash in ODIN TTL mode it overexposes like crazy in high ISO shooting. It gets worse the higher the iso gets. I thought I had a bad set so until I found 2 other complaining about this on the phottix usa facebook page. I have since confirmed with these 2 people, as well as the phottix usa tech support that this is indeed happening. The tech guy actually tried this on his own mitros+ which he had laying around. This happens both when using either a mitros+ or odin tcu as the on-camera transmitter.

    From what we can tell it doesn’t seem like the mitros+ is taking into consideration the ISO in its exposure calculation. It is almost as if it is set to a constant 400. (we have also noticed a underexposure when using iso 100.

    So to sum up. Mitros+ overexposes when used off-camera in Odin rx TTL mode.

    To further narrow it down we have test and confirmed that the mitros+ works great when being fire from an odin receiver (kinda defeats the point of the PLUS)

    I encourage those who have a mitros+ for nikon to test this function to see if you are having the same issue.

      Hi John C,

      Ok thanks for the feedback. There should be a firmware update coming soon for the Nikon version Mitros+. So hopefully that already covers these issues, but please let us know how you go (once its available). Thanks again.

  21. mark 5 years ago

    After some extensive testing using a flash meter I have two anomalies to report. The first one, I can confirm what John C writes above. OC (off camera) Mitros + in TTL mode with ISO settings starting around 640/800 and going above consistently over expose. At ISO 800 I’m finding that it over exposes +1/2->2/3. This happens when OC Mitros + is being controlled by either another Mitros + or a TCU. My TCU has the most recent firmware 1.06.

    The next anomaly has to do with controlling the manual power output of OC Mitros + triggered by either another Mitros + or a TCU. When going from 1/128 up to full power 1/1 or going from full power 1/1 down to 1/128 power this should be a seven stop power change, 1/128, 1/64, 1/32, 1/16, 1/8, 1/4, 1/2, 1/1. I’m only getting a variation of 4 1/2 to 4 2/3 stops over that range. The upper range 1/1 to 1/32 is fairly accurate but from 1/32 -> 1/128 I’m only getting 1/3 to 1/2 stop power change. I’ve tried this with both of my new Mitros + and get the same results.

    In addition, I get the same results triggering an OC SB900 mounted on Odin Receivers triggered by a Mitros + or TCU. The upper range of the output is pretty accurate down to about 1/32 below that the power change is only 1/3-1/2 stop. My Odin receivers have the latest firmware 1.06.

    It seems that the software that controls the manual power output settings of the Mitros + OCF needs some tweaking.

      Hi Mark,

      Thanks for that. They are working on a firmware update for the Nikon Mitros + to be available soon. Most of the other updates have included refinements to the power levels, so there should be some improvements with the new firmware.

      Have you had any issues with recycle times, or burst rates at low power levels? Thanks.

      • mark 5 years ago

        I haven’t tested that yet (recycles times). I’m generally shooting at hi-ISOs and fast apertures thus recycle times are seldom a problem. Therefore I’ve never even thought about testing for that issue. Just getting into the wedding season now and will be putting them through the paces more thoroughly soon.

        • Author
          Flash Havoc 5 years ago

          Ok thanks Mark.

          I’ve been doing some comparisons with the 600EX-RT, as there was a firmware update released for the Canon version. Its really after the Nikon update that this will be of more interest / significance.

          • Joe Appel 5 years ago

            I’ve been checking the Phottix website diligently, but still no firmware update 🙁 This isn’t the first time that I’ve heard about the power output issue that Mark is describing.

            Hopefully both of these issues will be addressed in the firmware update. Wedding season is coming and I’m anxious to get this all settled, so that update can’t come soon enough.

      • mark 5 years ago

        FH, regarding the recycle times: pretty disappointing. 🙁 I’ve used mine for several weddings now and I can confirm that the recycle times on the Mitros + are no-where as quick as my SB900 using the same battery brands. TTL on-camera with the Mitros, if I shoot more than two frames in succession not super fast but just trying to follow action at a wedding the 2nd frame will be about 10% underexposed but frames 3 and 4 will be at least 50% under.

        I’m becoming more and more disappointed by these units and Phottix slow response to getting a firmware update to us. I may go back to using SB900 with Strato II triggers.

          Hi Mark,

          Ok thanks. I’m not sure where they are up to with the firmware update. You could probably drop them an email, but they may not know themselves unless its very close to release.

          Hopefully its not too much longer though.

  22. Ryan 5 years ago

    Have the problems been fixed yet for the Nikon version? I would like to buy this kit, but am going to hold off on purchasing till the problems are fixed.

    • mark 5 years ago


      Not yet, this is so disappointing. I have yet to have a misfire with them but….

      The slow recycle times are really tough to deal with, the other issues I can painfully deal with them.

    • Joe Appel 5 years ago

      I’ve done 3 weddings over the past 2 weeks with my Mitros+ triggering SB800’s on Odin receivers.

      It’s been dead solid and the fact that I no longer have to deal with velcro and special cables (as with my RadioPopper JrX’s) has been truly wonderful.

      That said, I am NOT using anything in TTL. The Mitros+ is either turned off (simply being used as an Odin transmitter) or dialed back to around 1/64th power or so. Even at 1/128 power it blows out the subjects. Wanting just a little kiss of fill light from the camera I’ve taken to pointing the flash head upward and extending the bounce card.

      One thing that I’ve noticed on the off camera flashes is that I’ve had to turn them up to 1/8th power even at 3200 ISO to get an exposure of f/4-5.6. More testing is in order before I pass judgement on this because I’ve been using them in very big rooms so far that have been a little bit out of the ordinary.

      So yeah, the system has issues. Hopefully Phottix will be able to address them in a more timely manner than they have to this point, but it’s working well for me in my setup.

  23. John Crozier 5 years ago

      Thanks Mark,

      Let us know how you go.

      • mark 5 years ago

        I wish I could, I can’t get either the Mac or the Windows installers to work. Grrrrrr. They admit the Mac version firmware does not woe if your flash is being updated from the previous most recent firmware 1.03. Which mine are. But I can’t get the Windows installer to work under XP. So i can’t update my flashes until they fix one or the other.

  25. ryan 5 years ago

    OK. Here’s something rather interesting and very shocking. I bought the kelby kit and it comes with the Mitros+ flash and it does not have HSS. In the picture it is written in white letters onthe back of the flash using the down arrow key . My flash does not have the white letter stamping on it for HSS mode. I’m confused.

    • Author
      Flash Havoc 5 years ago

      Hi Ryan,

      I’m not sure why they HSS printing would have been changed. Maybe they have changed the position of the HSS button. But the flash definitely has HSS function.

      What does the use manual say about engaging HSS? I’m not that familiar with Nikon, but I thought this was done automatically with Nikon?

  26. mark 5 years ago

    From their website this morning:

    Update: There have been some issues reported with the upgrade apps. We are currently investigating and will repost when the issues have been resolved.

  27. ryan 5 years ago

    I’m just going to return the whole kit. I’ve been having missed flashes, kills batteries with in 15 min., over exposes sometimes with same settings, and now I can’t even update it because the update won’t work with Mac.

    I thought it was a great kit for a price, but now I think it has too many bugs to even bother.

    I’m off to research another wireless kit..

  28. mark 5 years ago

    I have some really disappointing news, I’m becoming quite soured over the Phottix company and their Mitros + units. I had such high hopes.

    I was finally able to upgrade to the latest firmware for the Phottix Mitros + for Nikon using a Windows machine and Windows 8. But the update (1.05) has made things far worse as far as controlling power levels of off camera speed lights, both Mitros + and Nikon SB900 units.

    Before the firmware update of 1.05 I was able to get a four stop power variation when going from 1/128 up to full power using either a TCU on camera or a Mitros + on camera to fire either another Mitros + or a Nikon SB 900 mounted on an Odin Receiver for Nikon. That should have been a seven stop range from 1/128 to full power.

    Now I’m only getting two stops when going from 1/128 to full power. Using either a TCU or a Mitors + to fire another Mitros + off camera. We have gone backwards.

    I get different results when firing an off camera SB 900 using either the TCU or a Mitros +. I get 3.5 to a 4 stop variation using this combo.

    If you have not already done the firmware upgrade I would recommend waiting.

      Hi Mark,

      That’s disappointing. But make sure you let Phottix know which issues your having now.

      I’ve only heard one other comment on the new Nikon firmware, and that was actually positive regarding the TTL exposures.

      Its a bit surprising really that they would still be having issues with the manual exposures.

      Hopefully they will get there eventually as its a great system otherwise.

  29. mark 5 years ago

    FH, I’ve got a running support ticket going with Phottix but their response their is not very goo. I also posted my finding on the Phottix USA FB page and they guy who maintains that page aid he would test his units this weekend and post back his finding.

    I’t been almost three weeks ago since they released this firmware update for the Nikon Mitros + units but they still have not fixed the update to work with the Mac OS.

    I haven’t had a wedding since I did the update so I really don’t know if it fixed the TTL problems or not. As far as the manual remote control of off camera units they have gone backwards and made things worse.

  30. Andrew 5 years ago

    Sorry to hear of your issues Mark.

    My Mitros+ ( Canon) is working flawlessly so far in conjunction with Odin triggers and 580 ex iis,…… apart from the annoying pre flash when in Odin RX.

    However I concur 100% about Phottix tardiness in replying to tickets and emails. I have sent quite a few ( questions) and received nothing as yet. When I take the link from automated emails from their ticket system, I continually get error messages. Again I report these problems …but silence is all I get.

    • mark 5 years ago

      Andrew, one good thing I can say about them, they never fail to fire. 🙂

      • Author
        Flash Havoc 5 years ago

        Thanks Mark, and Andrew.

        I saw in another post they are now aware of the ticket system issue and are looking into it.

        Yes the Canon Odin / Mitros+ is still arguably the best TTL system available. The main limitation with the Canon system is still the number of shots possible before heat protection slows recycle. Really only a small number of people have complained about that as an issue though, so it just depends on your needs.

        Hopefully they do get the Nikon version refined soon though.

  31. mark 5 years ago

    Well I have made some interesting progress on figuring out my issues with my Mitros +.

    Phottix USA asked me to send my units to Pro Camera in VA to be checked out. A very helpful nice guy by the name of Bob ran them through his testing and said that he could not find any issues with them. So I asked him how he was checking the power output? He said by firing them using the test button on the back of the unit. He had them set to manual and he got a full seven stop range when metering the output using a flash meter. Of course I never got anywhere near a seven stop range but I was triggering them by a TCU or another Mitros + and I got 3-3.5 stops at best. So I was triggering them by radio. So I asked him to run his test again but by triggering the OCF with either a TCU or another Mitros +. In other words firing via radio control and not the test button on the back of the unit. Guess what? His results were even worse. He always got the same reading, same output regardless of the power setting.

    So he contacted Photttix overseas and they explained to him that there is a pre flash that can not be disabled. To fire the flash off camera, the off camera flash has to be set to TTL and RX setting to work so you always get a pre flash even when controlling the power output manually by either a onboard TCU or another Mitros +. Thus to get a correct flash meter reading you have to have a very special flash meter to read the flash that happens less than a 1/4 sec after the pre flash. Essentially a lab tool. I don’t know of any meter on the market that can ignore the pre flash and read the 2nd output.

    So according to these guys there is nothing wrong with my units, they are working as they should.

    • Author
      Flash Havoc 5 years ago

      Thanks Mark.

      That all makes sense, except the delay in the test fire was designed to allow a regular flash meter to be used though. The pre-flash goes off, then the main flash a couple of seconds later.

      What results are you seeing on the camera histogram though? (shooting a plain wall, with no ambient light in the image). Thanks.

  32. S Lee 5 years ago


    I have a question regarding the crossbranding system. I have a canon camera with a Odin trigger and a 580EXII with Odin receiver. I just bought a nikon camera. Is any chance i use a Mitros+ for nikon to fire my canon flash with Odin receiver in manual mode?

    Many thanks.

    • Author
      Flash Havoc 5 years ago

      Hi S Lee,

      No, unfortunately they are different systems for Canon and Nikon. You would need a Canon Mitros+ or Canon Odin to fire the Canon Mitros+ or flash & Odin receiver.

      The Strato II do work across brands though, so you may be able to do some basic cross brand triggering in manual (no remote power control) using the built in Mitros+ Strato II receiver. That’s probably not much use in your current situation, but could possibly be useful somewhere in a cross brand system.

  33. mark 5 years ago

    Now that I understand what is happening with the pre-flash I can verify that I am getting correct off-camera manual exposures units either Mitros + and/or Nikon units. But I can only tell this by taking actual photos in a studio set-up and examining at the results. If I set up a scene in the studio and take actual photos I get a full 7 stop power range. If I try to meter the output with a flash meter and my meter does not have the ability to ignore the pre-flash then it appears that the exposures are not correct. Plus the pre-flash has a greater discharge level than manual settings going from 1/128 up to about 1/32 power. Once moving above the 1/32 power setting threshold my flash meter begins to record the increase in the output. So until I understood the pre-flash thing that happens with the Mitros + I thought I as only getting about 3-3.5 stop power variation from 1/128 to 1/1.

    I can verify for certain that the recycle times of the Mitros + are no where near as quick as what they are with Nikon units when using the same batteries. This results in under exposure and thus making it appear that the TTL is inconsistent. When photographing weddings I find the first two, maybe three shots in a row, at the most, will have correct exposures with an on-camera Mitros + set to TTL. After the third shot exposures fall off rapidly. I’ve tried both PowerEx 2700 and Eneloops.

  34. mark 5 years ago

    I’m beginning to think that Phottix is a joke company.

    Yesterday, 11/5/14, they notified me via e-mail that they have a new firmware (1.06) update for the Mitors + for Nikon. So I go to the download page and download the Mac version wondering if the updater will work this time on my Mac. The last update 1.05 would not work under Mavericks. Well guess what the new updater will not work under Mavericks or Yosemite. Why bother posting an updater for Mac if the updater will not work under the two most recent Mac OS?

    So I download the PC version and the updater will not work under Windows 7, works under XP, I did not try it under Windows 8. Is it that difficult to test your update software before you release it to the public? Good grief.

    So I run the installer on two units. It seems to work fine except for this step, from the PDF instructions item 9.) it says ‘Click the Icon image (in the installer software). Select the .FIF upgrade from the upgrade archive folder. The status of the upgrade will be displayed in the progress bar. (Image3)

    Only problem, there was no .FIF file in the folder after it had unzipped. The updater software says the firmware was updated to 1.06 so I don’t know if this even matters that there was no .FIF file. Who knows.

    The latest update (11/5/2014) has not made any changes in my two flashes.

    So how did the updater do, did it fix my issues?

    The one unit that was firing intermittently is still doing that. This morning I put that flash on a D4 and the first two shutters clicks the flash did not fire, then it fired twice, missed again fired twice more then missed three times in a row.

    The other flash fired three times first thing and then missed the forth shot then fired again. It is also under exposing by one full stop in iTTL mode.

    It is so unfortunate because the radio system works perfectly but as a flash these things are a joke.

    These are shots with roughly a half sec between each shutter click, so they are in close succession to each other but not machine gunning it either. My SB900s have no problem keeping up with this type of shooting.

  35. mark 5 years ago

    Well Photix China has replaced my two original Mitros + for Nikon, I just got the replacements today and I finally have solid recycle times. Recycle times that can keep up with normal consecutive shots. With the previous units by the third or forth shot the flash would not fire when shooting on-camera TTL.

    The on-camera TTL is still under exposing by 1.5-2 stops but I can live with that now that I have units that will keep firing.

  36. Peter A 5 years ago

    Mark, good to here about your struggles! I’ve keep away from the Mitros+ based on the recycle of my MitrosNs, but I like most of the features. Good to know they are making progress! Somehow I’m not fully convinced that increasing recycle time by underexposing by 2 stops is a complete fix.

    Stay with it and keep us updated!! Thanks!

  37. Jason 4 years ago

    Dave, I had some similar issues tonight when using the Mitros+ for a wedding. I have 4 Sony flashes fired by four Odin receivers and decided to pic up a Mitros+ to finally have some on camera fill. The issues started when I used the Mitros+ on my main body to trigger the other flashes as well as the Odin transmitter on my second body. The Odin never had any issue when shooting however anytime the Odin was powered on, the Mitros+ would have CRAZY exposures. Every flash would fire 1/1 power or not at all. Some would fire, some wouldn’t. Luckily I was able to troubleshoot and figure out that trying to have the Mitros+ and the Odin both in commander mode was causing the issue. As long as I turned off the Odin when using the Mitros+, it worked flawlessly.

    I was very disappointed but I had intended on getting rid of the 2 Odin transmitters I had anyways. My worry now is that I will have the same issue with a second Mitros+ on a second camera as another commander. If they won’t play well with each other, I may be out of options.

    Turning the one I am not using “off” may work but could leave me in a bind if I need one camera and have to wait for the flash to boot/power up before I can take a shot.

    Anyone else have any experience with this?

  38. Jason 4 years ago

    I actually was able to get my hands on two of them today (Mitros+) and with an hour of shooting with one of them on each of my bodies can confirm that they can both be used at the same time as commanders.

    I also was able to find out why I was having such an issue last night with my Odins and the Mitros+ combo. Seems as when you have the default setting of Auto Focus for the flashes, they will continue to run the focusing motor of the flash changing zoom levels. Especially if you’re using a zoom lens.

    I turned off the Auto zoom feature on both flashes but they would still try to adjust based off of my zoom level on my lens.

    Finally, I went into the zoom and set to 24mm on the channel and didnt have any additional issues with the transmitters fighting for control or the flash zooms constantly adjusting.

    Furthermore, I even attempted to use my Odin transmitter again and set it to 24mm as well and it played perfectly with the Mitros+. No issues.

    I will be shooting another wedding tomorrow and will field test again with each combination to verify more and keep you posted.

  39. Michael 4 years ago

    All, I have 2 Mitros+ for Canon and can confirm that after field testing these in intense event environments (NYC Bar/Bat Mitzvahs) that the flashes do indeed have reliability issues triggering off camera flashes. I have a Mitros+ on each camera body (5D mk II and III). They are setup in Odin TX mode on each and trigger my off-camera Cheetahlights connected to Phottix Strato II receivers. I first got them in December and used them for 3 big events and they worked nearly flawlessly. Then on the 4th event, I stated to notice they would fire once then misfire, then fire, then fire, then misfire. Other times, they would not fire at all for 3 or 4 frames, then fire on the 4th. It was this complete randomness that I began to get extremely frustrated. They behaved exactly as Mark describes in his post above. I came home and tried them at home and they fired every time. Next event they worked great in the first hour, then randomly misfired throughout the night. Next event, was in a smaller space and they fired nearly flawlessly, so I can’t predict when they will work and when they won’t, but it might be related to distance? I use them in the most basic mode – manual – on 1/64 power and trigger the other lights in manual mode. The load on them is so light that I can’t figure out why they misfire randomly.

    I really really want to love these flashes. They are such an elegant off-camera solution, but they are not reliable in a real-world intense shooting environment. It’s a bummer b/c I’ve sold my Canon 600EX RTs and invested in a total Phottix system after the 3rd event testing them out. It wasn’t until they’ve been put to use after 4 weeks that they started to behave erratically.

    Any advice for me? What is the best way to contact Phottix to get a worthy response?

    • Author
      Flash Havoc 4 years ago

      Hi Michael,

      I’ve heard very few complaints about the Odin or Mitros+ not firing remote flashes reliably. Mark even states in the post above that the radio system works perfectly.

      Mark’s issue was with the Mitros+ on-camera not firing consistently, and this is not an uncommon complaint when it comes to recycle times with the Mitros+ if they are being pushed hard. Though I think Phottix have made some progress there.

      So are you saying the flash on camera is firing fine, while the remote flashes are not?

      Steve at Phottix dot com would be the person to contact if you haven’t found a resolution.

  40. Michael 4 years ago

    I’ll reach out to him and report back my findings. Though to answer your question, both the on-camera mitros plus flash and remote phottix strato ii receivers would not fire consistently. This was after about an hour or 2 of use on an event.

    • Author
      Flash Havoc 4 years ago

      Hi Micheal,

      I don’t think the remote flashes will fire if the on-camera flash is not ready, so that’s why it can come back to the slow on-camera flash as the limiting factor.

      • Joe Appel 4 years ago

        Yes, that has been my experience as well. If the on-camera flash isn’t ready then the remote flashes won’t work either. No matter if they’ve already recycled and are ready to fire.

        The only solution that I’ve found to be practical is to use the on-camera Mitros+ only in Manual mode (usually set at 1/16-1/32 power for fill flash). TTL slows everything down too much to be of any real world use. My off camera flashes are Nikon SB-900’s triggered by Phottix Odin receivers.

        I used this setup for 30 weddings last year and it served me well. It’s disappointing that the Mitros+ doesn’t work well in all modes, but I can live with it.
