TTL and Remote Manual radio triggers have come a long way in the last few years, with reliable options now available in every price range. They can offer a lot of convenience and features over basic manual triggers. Compatibility is the key word here though, as camera brands, models, and lights used, will often effect the options and functions available.

Remote Manual Power Control Only, NO TTL  (TTL flash on camera may be supported)

 Radiopopper JRX PERMALINK

Radiopopper JrX Studio

Around – $170 a set – Tx & Rx  + $20 – $30 for speedlight hotshoe / cord.

Universal – Single Firing Pin

Radiopopper JrX are great system for Remote Manual Power Control if you have access to inexpensive older Nikon TTL speedlights like the SB-24, 25, 26 28, 80dx etc or SB-600 & SB-800, any of the Canon EX speedlites, and Paul C Buff Alien Bees monolights. The JrX have fast simple dials on the transmitter to change power levels for 3 groups of flashes. The main limitation is Nikon Flashes from the SB-900 onwards are no longer compatible with the JrX remote manual power control, and HSS is not supported with any speedlights.

Compatible with Radiopopper PX TTL triggers

Allow Flash on Camera – YES, if Tx is connected via PC sync cord to camera

Radiopopper JrX are the only Manual triggers offering Remote Manual Power Control via the simple quench pin system. This is a brilliant system if you have access to inexpensive older Nikon film camera TTL flashes like the SB-24, SB-26, SB-28 SB-80dx, etc at reasonable prices. They will also work with the SB-600 & SB-800, any of the Canon EX ETTL flashes, and Paul C Buff Alien Bees monolights as well. (They will still fire SB-900 etc and most other lights, just not control their power level remotely).


  • Remote manual power control with many TTL capable speedlights & Alienbees monolights
  • Universaly compatible with most cameras
  • 3 groups with simple control dial on the Tx
  • Great range and reliability – 100 – 500m
  • Fast sync speed – full x-sync (1/250th etc).  Electronic shutters aprox 1/1200th +
  • 200V trigger voltage
  • Compatible with Radiopopper PX transmitter
  • Standard 3.5mm headphone sync sockets
  • Light Meter use possible
  • Great service from Radiopopper


  • No HSS available with speedlights
  • No locking ring on the transmitter
  • No hotshoe on receivers
  • Non standard CR123A batteries
  • No lanyard strap or hole for a strap to hang or mount the receiver
  • Shutter release is not a standard feature (works but requires a cord)
  • No flash wake up feature
  • Separate USA and European versions


The JrX are also good solid manual triggers with fast sync speeds and high safe trigger voltage. Unlike some of the TTL triggers available, the power changes are separate to the flash fire signal, so fast sync speeds are possible and there are no pre-flashes at all, which means no issues using light meters either.

The JrX transmitter also use a simple single firing pin on the foot which means they can be used on any camera, or even held off camera to change power levels and take a meter reading with the test fire button.

Older Nikon flashes are becoming in limited supply though and the SB-900 are no longer compatible (SB-800 and SB-600 are compatible). Current Canon EX flashes are compatible as well, it’s just that you’re paying for the extra ETTL and High Speed Sync (HSS) features with those, which may be better exploited with the many inexpensive TTL triggers now becoming available.

The JrX studio receivers also require an extra cord or hotshoe to connect to your flash unit, which is at least $20 from flashzebra.com, and $30 for the Radioppoper “cube” hotshoe.

Backward / Forward Compatibility – The JrX are also compatible with the Radiopopper PX TTL system and can be used with the JrX or PX transmitter to control Alien Bees monolights (but not the later Einstein).

The Radiopopper JrX and Px also have separate USA (FCC) and European (CE) aproved versions so you will need the correct version for your location.

Aokatec AK-TTL

Around – $110 a set – Tx & Rx

Canon – Nikon – Sony – Pentax – Olympus – via the same units

AK-TTL are a relatively new simple optic to radio converter, working on a similar principle to the well established Radiopopper PX. They convert the optic based wireless flash system already in many cameras to a much less limited and more reliable radio communication. The Major advantage here is the AK-TTL offer a solution for Pentax and Olympus users who currently have no other radio based alternatives available. The same units can also be used across a number of Camera brands, as long as they have an existing optic wirelss flash control system available. The other advantage is for solid flash on camera mounting avoiding possible weak Pass Through Hotshoes.

YongNuo YN-622C & YN-622N

Around – $80 a set – 2 Transceivers – FULL REVIEW Canon

Canon – Nikon versions available

YN-622 are really a turning point with inexpensive TTL triggers. They follow the similar Pixel Kings (shown bellow) but offer significant refinements in general function and features. Most notably adding TTL ratios and a Pass Through Hotshoe for TTL flash on camera use. And all at a significantly lower price. The Canon version YN-622C now offer the full functions available through the Canon Flash Control Menu, ETTL ratios, Remote Manual Power Setting in 3 groups, HSS to 1/8000th, and Second Curtain Sync. The one step backward though is a lack of USB port for firmware updates for future camera models. Also as good as the 622C are they are still limited by the Canon Flash Control menu, where higher priced options offer more control and convenience with their own interface directly on the transmitter units. Functionality can depend on camera and flashes used. The Nikon version does not have control through the camera menu, but it does allow a master flash or SU-800 controller to be mounted on top of the transmitter and used as the interface for adjustments.

Not currently compatible with any other YongNuo Triggers.

 Phottix Odin PERMALINK

Phottix Odin

Around – $330 a set – Tx & Rx – FULL REVIEW

CanonNikonSony – versions available

Phottix Odin are a powerful system, and at the same time incredibly simple, reliable, and hassle free to use. The convenience and solid performance over the cheaper (and even higher priced) options has gained the Odin quite a following as an ideal mid priced solution. The Odin are powerful because they allow mixing ETTL and Remote Manual Power setting in any of 3 groups, all shown together clearly on the LCD screen, and easily accessed for quick adjustments. The Odin control everything through their own clear and simple interface, so they work exactly the same on any compatible camera whether they have exisiting flash control menus or not. The Odin have HSS to 1/8000th, Second Curtain Sync, combined FEC up to 6 stops, and Remote Manual Power setting in 1/3rd stops. Manual flashes and studio lights can also be triggered with Odin, Strato II, or Atlas receivers. UPDATE – Now compatible with the Mitros + flash unit with Odin transceiver built-in.

Please also see the Phottix Odin review for full flash and camera compatibility HERE

UPDATE – Now compatible with the Mitros + flash unit with Odin transceiver built-in.


Great Features (Canon version shown – Nikon and Sony versions have similar functionality) –

  • Everything is controlled through the one simple Odin transmitter, this is really the standout feature of the Odins.
  • Most importantly they work flawlessly with plenty of range and no misfires or radio interference issues.
  • Manual and ETTL can be used and combined together at the same time, in 3 different groups.
  • Compatible with most Canon EX flash units  420ex, 550ex, 430ex, 430exII, 580ex, 580exII. (& some Nissin flashes)
  • Compatible with all Canon ETTL II camera bodies from the 20D onwards, no special flash control menus required.
  • Up to 6 stops of FEC Flash Exposure Compensation in TTL (that is in combination with the cameras FEC)
  • Backward compatible with the Phottix Strato II and Strato. (Strato/II Transmitter will NOT fire the Odin Receivers though)
  • HSS (high speed sync, up to 1/8000th), Second Curtain Sync, and FEL (Flash exposure lock) works.
  • Remote Control of the Flash Zoom Head, in Manual or Auto (auto follows the lense zoom length).
  • Hypersync, high speed sync with monolights. (Not an official feature but this does works in many cases)
  • Firmware updates via built-in USB ports.
  • 1/3rd stop manual power adjustment, even for Canon 550ex, 430ex & 420ex flashes which usually do not support this.


Limitations –

  • No Flash directly On Camera – this is possible though using an on-camera flash bracket and extra receiver.
  • No AF (auto focus) Assist Light. – As above still possible with a bracket and flash or ST-E2 mounted above camera.
  • Light meter use is limited, even in remote manual use.
  • TTL compatibility currently only with Canon, Phottix and some Nissin flash units. Not YongNuo or Sigma etc.


Phottix (Canon version) –

Photographers can wirelessly trigger TTL flashes, retaining full TTL functions, as well as remotely control power and flash zoom settings. Shooting with off-camera TTL flash has been made incredibly easy.

Say goodbye to manual mode, proprietary flash-based triggering, or setting values on your camera LCD – reliable wireless radio-based TTL triggering and remote power control is here.


  • Wireless 2.4GHz. TTL and Manual Flash Triggering
  • Remote power control of groups in TTL with +/- EV adjustments (3 stops in 1/3 stop increments  – 18 different levels.)
  • Mix TTL and Manual flash – fire some groups in TTL, others as 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 manual mode flash power control
  • Remote flash head zoom adjustments – auto or manual
  • Compatible with Phottix Strato 4-in1 and Phottix Strato II Multi 5-in-1 Wireless Triggers.
  • Upgradeable via built-in USB ports.

What does the Odin offer?
The Phottix Odin TTL Trigger consists of an on-camera transmitter and control unit (TCU) and receiver units for compatible hot shoe flashes.

The Odin offers photographers four wireless channels and three flash control group designations. Flashes can be controlled in traditional Canon TTL ratio modes A:B with EV +/- adjustments of three stops.

What makes the Phottix Odin unique is the ability to designate groups in TTL/Mixed mode. Individual groups, A, B, C, can also be controlled in TTL mode with EV +/- adjustments. Groups can also be set to Manual mode, adjusting power levels remotely, or turned off.

Zooming ahead
Flash head zoom can be set to be dynamically adjusted as photographers adjust their lenses. Flash zoom can also be easily adjusted manually and set statically from 24 to 105 mm. The Phottix Odin system will also trigger compatible non-TTL flashes and studio strobes.

Compatible with the Phottix Strato series
The Phottix Odin TTL Flash Trigger for Canon is compatible with with Phottix Strato 4-in1 and Phottix Strato II Multi 5-in-1 Wireless Triggers. Current Phottix users will have no problem adding the Odin to their current triggering systems. As the world of cameras and flashes is always changing the Photix Odin system can be upgraded when needed using the built-in USB ports.

The four-channel, 2.4 GHz, transmitter and receiver units work at ranges of more than 100 meters and accept AA batteries. Phottix Odin TTL Flash Trigger sets with a TCU and Receiver will be available, as will as individual receivers.

Radiopopper PX

Around – $380 a set – Tx & Rx

Canon – Nikon – via the same unit

Radiopopper PX are an optic to radio bridge. They simply convert the optic based wireless flash system already in many Canon and Nikon cameras, to a radio based communication, with no line of sight, sunlight, or short range restrictions. The PX functionality is basically the same as your cameras existing wireless optic system – TTL, Ratios, HSS to 1/8000th, and Remote Manual Power Setting. Manual flashes can be triggered with JrX receivers, or remotely control the power levels of Alien Bees monolights (not Einsteins) with JrX Studio receivers (though the JrX transmitter is actually more convenient for this). Mounting receivers to the flashes can be a bit more awkward than regular hotshoe based triggers, though the PX transmitter has the advantage of solid direct flash on camera mounting rather than some flimsy pass through hotshoes. Since the release of Canon’s own radio flash system the PX price has dropped from $249 to $189 for each unit. US and European versions are required.

Canon 600EX-RT & ST-E3

600EX-RT – $550  ST-E3-RT – $300

Canon – version only available

In march 2012 Canon became the first camera manufacturer to introduce a radio based wireless flash system with transmiter and receiver built into the new 600EX-RT Speedlites. As well as the new low profile ST-E3-RT  transmitter unit with matching interface. The RT offer up to 5 groups, ETTL, Remote Manual, and HSS to 1/8000th. With 2012 cameras onward you have access to a Nikon style interface which allows mixed ETTL and Manual in any group, while adjusting FEC or manual power in 1/3rd stops for each group. For many wedding and event photographers the big advantage over third party radio options is the solid direct flash on camera mounting, avoiding flimsy pass through hotshoes or additional transmitter units on the camera. No extra transmitters, receivers, cords or batteries to manage. Limitations include a lack of separate receiver option to trigger other manual flashes or studio lights, (let alone remote control them). No AF focus assist light on the ST-E3-RT, and no Second Curtain Sync available off camera, (which many cheaper 3rd party options already provide). The large clear LCD is nice, though the interface its still more fiddly than the instant access to basic adjustments many photographers would really prefer. The convenience of a reliable integrated system though makes the RT one of the most convenient options for many wedding and event photographers.

      Hi Juan,

      The first question would be which model Vivitar do you have, and is it HSS and TTL enabled to start with?

      There is mot much feedback with Vivitar regarding TTL trigger compatibility so it would be better to stick with the better known flash options. If it is TTL and HSS enabled there may be a possibility it will work with some triggers, but that may still take trial and error to discover.

      Hi there, there is no dedicated Pentax option as yet, but if your Pentax has optic wireless flash built in you can use the Aoketec AK-TTL to convert the optioc signal into a more reliable radio based signal. The AK-TTL will only do what your camera and flash system already provides, just more reliably without line of sight issues etc. http://flashhavoc.com/ttl-radio-trigger-guide/#Aokatec_AKTTL

      Hi Paul,

      I haven’t tried that specific combination of gear, but I don’t see any reason why the PW Plus III would not fire a YN-568EX connected via Sync cord as you mentioned (from the D800).

      The Plus III are a manual only trigger though, so they will not do FP HSS at all. Only Hypersync if used with a TT1 or TT5 transmitter unit. Hypersync is more suitable for studio / monolights though, as you have to fire at full power all the time.

      Your best option is to either wait for the HSS enabled YN-622N trigger coming soon, or use a genuine Nikon flash unit like the SB-910 etc with PocketWizard Control TL (TT1/TT5). With the Nikon flash you would be safe with other good options like the Phottix Odin too.

        the Phottix Odins, PocketWizard TT1/5, Radiopopper PX & JrX, Aokatec AK-TTL, are all good options.

        Yes, and also the most expensive

          The Aokatec AK-TTL are in the same $100 range as the YongNuo and Pixels etc.

          The YN-622N will be out soon, you’re not going to find any cheaper than those.

    The MK-900 is compatible with the >>PIXE king II<< at HSS 1/8000s ?

      Flash Havoc 7 years ago

      Sorry no the MK-900 does not support HSS. I haven’t heard any reports of it being used with the current Pixel Kings, so I don’t know how compatible they are otherwise.

    Thanks for putting this great flash radio trigger round-up! Really helped me a lot! Coming from CLS and using HSS I’m looking for a radio trigger that can work like my Nikon CLS. Ie. Do HSS and adjust flash settings on camera! With regards to TTL i’m not really fond of it right now as I rely setting my flash power manually and doing it remotely on my camera is one i’m looking for for radio triggers. Odins looks impressive right out of the bat! But curious to see what else it out there from Pixel King and Yungnuo 622!

    I know these don’t do TTL, but why no Cactus? Also, i just heard of Scott Robert Lim units.

    • Strobe-X 7 years ago

      oops..i didnt’ see you had a separate review for all manual radio triggers.

  8. d7kographer 7 years ago

    Excellent overview on the radio triggers available for TTL and manual control. I decided to go with the Aokatec AK-TTL several months ago and I am very pleased with them. I shoot with a Nikon D5100 and D7000 and and a set of 2 x Nissin Di866 and 1 x Nissin Di622 flashes. The D7000’s commander mode is great and can control two groups of flashes in TTL and manual control over 100m using the Aokatec AK-TTL radio triggers.

    The D5100 I have to use one of my Nissin Di866’s on camera and use it as a commander to control the other flashes. I could do this without the Aokatec AK-TTL radio triggers but I have the earlier version Di866 flashes and the TTL CLS wireless range is not good. Using the Aokatec AK-TTL radio triggers I get at least a 100m range.

    I am now looking at getting either a Nikon SU-800 or another flash such as the Nissin Di866 Mk2 so that I can control 3 groups instead of 2.

    I was very interested in the Phottix Odin system, however they dont really support 3rd party flashes working with their system so i gave it a miss.

  9. Captaindash 7 years ago

    Is there any trigger system out there that will remote power control (I don’t care if it’s TTL or not, I just want to be able to remotely control my power output) Nikon, 3rd party, AND Einstein units? I currently only use Nikon and Einstein and I know pocket wizard can do them both, but those 3rd party speedlights (yongnuo/phottix/nissin) seem like a way better deal than the nikon ones so I wanna pick some up, but not if I can’t control their power output remotely. Even if I have to stick with a single 3rd party manufacturer for speedlights because it, it’d still be more choice than just nikon. I just want remote power control for speedlights (Phottix Odin etc) AND my Einsteins. Please, please tell me. I’ll be your best friend (or I’ll promise to never talk to you again, whichever you prefer).

    Then again, if every manufacturer of everything keeps coming out with Canon stuff a year ahead of the Nikon, I just might have to switch.

      Hi Captaindash,

      Nissin Di866 II generally work ok with Pocketwizard TT5 as far as I’m aware.

      But really the TT5 itself is the part that’s adding the cost to each flash, if that’s what you’re concerned about.

      No there is no other option to control Einsteins and TTL flashes with the same transmitter.

      Though you could use the Cyber Commander (or PW) to adjust the Einsteins, and then look at something like the Godox V850 remote manual speedlights. They are only from around $120 each even with the receiver.

      The FT-16 transmitter controls the remote manual power level of the V850, but like the Cyber Commander, and even the PW AC3 now, they can all be used in hand as a remote control, and just one of them would be used to actually connect to the camera and fire all the flashes.

    Are their any radio triggers for the Panasonic G6 offering off camera TTL?

      Hi Chris,

      Sorry no, not that I’m aware of at this stage.

      The Aokatec AK-TTL optic to radio conversion triggers are the only ones that have a work around for Olympus and Pentax, but they still don’t work with Panasonic as far as I’m aware.

  11. Gianni 6 years ago

    hi there,
    thank you for this useful guide!
    My name is Gianni,and i’m writing from Italy.
    i have a metz 52 af-1 and 50 af-1 that i use in remote (using I-TTL functions) with a nikon D800 and D7000
    recently i’m having some range issue (especially with the 52 af1) and i’m wondering if there is a solution to switch to radio mode (without loosing ttl functions) without buying new speedlights.
    thankyou in advance,

      Hi Gianni,

      Unfortunately I do not have that much feedback for compatibility for third party flashes with Nikon TTL triggers.

      Though the most likely to be compatible would be the YongNuo YN-622N.

      Another fairly safe option would be the Aokatec AK-TTL, though they are a little less convenient to mount.

      • Gianni 6 years ago

        thank you very much for your fast reply!
        i appreciate it very much!
        i will check these two options.

  12. Gianni 6 years ago

    i’m gianni again.
    i would let you know, that i have tested the
    Yongnuo YN-622N-TX i-TTL Flash Controller + YN622N Trigger
    with Metz 50 AF-1 and Metz 52 AF-1
    and…. 100% compatible!!
    hope this news can be useful for you!

      Ok great to hear the YN-622N worked out for you.

      And again thanks for the compatibility feedback on the Metz flashes, that’s very helpful thanks!

    I have been getting conflicting information about the Pixel King Pro working with Yn 568EX Nikon. So does the YN 568EX work will Pixel King Pro Nikon?

    • Author
      Flash Havoc 6 years ago

      Hi Robert,

      Pixel are listing the Nikon version YN-568EX and YN-565EX as not compatible with the King Pro.

      The Canon version King Pro and YN-568EX work together, though there can be some quirks and inconsistencies. Pixel list those as compatible, though note – “abnormal phenomenon may occur when using YongNuo flashes”.

      So its possible the Nikon versions may work together to some degree, though very likely not as consistently as you would hope. So I wouldn’t be surprised if there are conflicting reports of compatibility. In general they are likely a combination best to try and avoid. Thanks.

  14. Dave 6 years ago

    I’m wondering if the Phottix Strato TTL offers [TTL] or standard, center-weighted TTL with cameras like the Nikon D800 and D300s and SB-800. I’m wonder if it works with Nikon’s FV Lock (flash value lock).

    I’d like to get rid of the Nikon SC-17 and 28 TTL cords when using a wedding/press flip bracket.


    • Author
      Flash Havoc 6 years ago

      Hi Dave,

      I’m not that familiar with the Nikon TTL system myself, though I would be surprised if the Strato TTL do not provide FV lock and the TTL options as you would have with the flash on camera or on the TTL cord.

      I haven’t really come across anyone that is using radio triggers like this instead of a cord though. You would have the weight of a couple of extra sets of batteries to start with. I think I would personally prefer to make a custom TTL cord that’s made neatly to size.

      You would be best to contact Phottix though if you want to get a confirmation on the Strato TTL functions. Thanks.

    I’ve set an email to Phottix.

    I highly appreciate all the information provided. Keep up the great work.
    I have YN-622N, YN-622TX and Lumopro lp180. I can trigger the flash but unable to change the power/output of flash. Can you please help and let me know how to do this? I even tried pc sync to 3.5mm cable.
    Thanks a lot.

    • Author
      Flash Havoc 4 years ago

      Hi Ram,

      Thanks for that, unfortunately that is not going to work though in any case. The LP180 are simple manual flashes with no remote control possible with any radio triggers.

      The later LP180R have a Phottix Odin radio receiver built inside, for remote manual use only. They will not work with the YongNuo YN-622 transmitters though.

      To have control with the YN622 triggers you need to use full TTL flashes from Nikon or YongNuo.

    I have recently purchased Sekonic L-478DR and I need to now the channel Frequency ? I need to pair Sekonic L-478DR with my Huhnel Tuff TTL for Nikon , Due to Sanctions on Iran, I am unable to purchase Pocket Wizard Plus III and its accessories , is there a solution or any other solution rather that Hahnel and pocket wizard by any chance. Any pro comments will be highly appreciated .

    • Author
      Flash Havoc 4 years ago

      Hi Ramin,

      You can’t link the Hahnel triggers with the Sekonic meter via radio unfortunately. You could possibly attach the meter to a Tuff transmitter via PC sync cord, though I don’t have the Hahnel triggers to confirm that will work. Otherwise you can just set the meter to wireless mode, and it will take a reading when it see the flash go off. That may be an issue if you’re using TTL though, due to the TTL pre-flashes.

      If you want a linked system other than PocketWizard, then the Phottix Strato II, and Elinchrom Skyport both have Sekonic meters available now. They are manual triggers only though (as are PocketWizard Plus III).

    Do you know if the mini TT1 will hyper sync my Nikon sb – 24’s connected to my plus ii’s?

    I know remote Ttl will not be an option, I just want to know that I can shoot faster than 1/200th of a second on my d600 with a mini tt1 and Nikon sb 24’s connected to my plus ii’s.


    • Author
      Flash Havoc 4 years ago

      Hi Daniel,

      Yes they should. Though you need to keep the SB-24 on full power to have a long enough flash duration. So its generally not the most practical thing to use with speedlites, though it should work.

  20. Daniele 3 years ago

    Hi everybody.

    After several test I can say:

    – Pocket Wizard are really expensive and they don’t work at all: do not waste your money

    – Yongnuo (YN622C-TX and YN622C II) are ok and work well but:

    a) you cannot modify the Alien Bees power from the TX

    b) to get the HyperSync on Alien Bees (set the C.FN 01 to 0,0) you have to add an hot shoe adapter on the YN622C II because if you get the cable direct from the Yongnuo receiver PC sync port it doesn’t work (insane)

    But my question is: is it that big to ask a transceiver or a transmitter and a receiver that:

    – works fine with hot shoe flashes: e-ttl, hss, manual and all the functions like you’ll have a flash on hot shoe camera

    – works in ttl with light strobe (in my case with Alien 400 and 800) (ok, maybe this is too much to ask :-P)

    – works to set manual remote control and get the HyperSync from studio strobe (always my Alien Bees)

    If I’m right at today the only option for my first and third request are Pocket Wizard but since they don’t even trigger…or Yongnuo build a remote power control for Alien (like PW AC9) or Radiopopper get a software update and let set an “HyperSync” function like Yongnuo does or, even better, like Phottix Odin that has a scale from 0 to 5… (http://flashhavoc.com/phottix-odin-ods-over-drive-sync/)

    Any suggestions from you, Flashhavoc?


    • Author
      Flash Havoc 3 years ago

      Hi Daniele,

      Unfortunately you are never going to be able get TTL with the Alien Bees. They are not IGBT flashes to start with, so for that reason alone TTL is never going to work there. Though the flash really needs to be designed for TTL from the factory in any case.

      That’s why even many Einstein owners have purchased AD600B / XPLOR 600 to fully integrate with their TTL and HSS system.

      As you mention, I don’t think there are any triggers other than PocketWizards which can control the power level of Alien Bees, while also providing TTL and HSS with speedlites.

      The Alien Bees Cyber Commander transmitter provides remote power control separate to firing the flashes, so that can be used in hand as remote power control for the Alien Bees, while other triggers like the YN-622C or Godox X1 are used for firing the flash and providing Long duration sync delay.

      I’m not sure what you mean by the PC sync port is not working for Supersync with the YN-622C II receiver. That’s the main way they should work.

  21. Daniele 3 years ago

    Actually with Radiopopper Jr2 you can remote control the Alien Bees power… (http://flashhavoc.com/radiopopper-jr2-released/)

    If using PC Sync from YN622C-TX to fire Alien Bees 800 in SuperSync/HyperSync…as we want to call it… (https://i1.wp.com/www.canonwatch.com/wp-content/uploads/2015/08/622IIC-5.jpg) the SS doesn’t work.
    Mounting an hot shoe and use it’s own PC Sync (http://www.photogearetc.com/media/catalog/product/cache/4/image/500×500/9df78eab33525d08d6e5fb8d27136e95/s/c/sc_2_hot_shoe_adapter_front_pc_connector.jpg) the SS works

    I have a set of Yongnuo 622N triggers and a TX unit. How much compatibility should I get with a Meike MK910 flash unit?

    Can I change the settings remotely from the TX Unit on my camera?


    • Author
      FLASH HAVOC 2 years ago

      Hi Chris,

      I’m really not too sure about that. In general we have found its usually not worth the hassle of mixing third party gear like that if you can avoid it. Even if they work well together at the beginning you may change cameras or update firmware etc, and then find you have new compatibility issues.

      The YN-685 are around he same price as the MK910, and they already have a YN-622N radio receiver built inside, so you would be better off sticking with a compatible YongNuo flash like that.

  24. Jean-Pierre Rateau 2 years ago

    I have a Canon 6D, a Canon 430EX III-RT AND a Metz 64 AF-1. I would like to know which transceiver would be the best and also if a light meter really needed now a day
