Pixel King PRO – For NIKON – Now Availaible

The Pixel King Pro, and King X, ITTL and HSS enabled radio triggers for Nikon DSLR cameras, are now available from the Pixel Ebay store for $157 a set, and they should start reaching stores and Amazon etc shortly.

The King Pro and King X are a major upgrade from the previous Pixel King for Nikon (which were really very limited in function), and with a full ITTL pass through hotshoe, the King Pro offer functionality not really seen before in any other current radio triggers available for Nikon.

Remote flashes can be controlled in a mixture of ITTL and remote manual groups, while a flash mounted above the transmitter on camera, can also be used in full ITTL or manual.

Functionality is very similar to the recently released Canon version, which you can see a full review of here.

Pixel King Pro & King X


I have had a quick hands on look at the King Pro for Nikon, but not being all that experienced with Nikon gear I have sent them off to a crack team of Nikon users who are currently putting then through their paces.

A couple of things I noted different from the Canon version –

– Firstly the screen has already been updated and the pixels are much more of a black color (or shade), so they are easier to see without the backlight on. But the screen is also even more clear and contrasty with the green backlight on now as well. I would suspect this update is likely already in the Canon versions now too.

– The second difference is that there are + or – 5 stops (10 stop range altogether) of Flash Exposure Compensation available on the controller, compared to +/- 3 stops on the Canon version (though Canon do add to the cameras FEC settings, providing up to +/- 6 stops together)


Other things to note –

– The new King Pro and X are now also fully compatible with the previous King for Nikon as well.

– Pixel have also provided a list of third party flash compatibility here. It seems the later YongNuo TTL flashes are not compatible, while some Oloong and Metz are.

– Pixel may still be tweaking firmware to iron out bugs and compatibility with different cameras etc. The latest firmware can be found here – http://www.pixelhk.com/down/kingpronikon/

And make sure to update the previous Kings if you would like compatibility with those – http://www.pixelhk.com/down/KingNikon/

Pixel King Pro

We will try and put together a review of the King Pro and X for Nikon once they have been given a good run. For now the Canon review here has a lot more detail of the general functionality of the King Pro and King X.


NOTE 15/3/2014 – As of firmware V104 (and earlier) the Pixel King Pro for Nikon can not read the ISO from the camera! 

So if the the flash power is set in manual mode 1/4 for example, and the ISO value is changed on the camera (from 100 to 6400) the same light output will appear in the images, regardless of ISO changes. This may be rectified in a later firmware versions.


Price and Availability –


The King Pro and King X set are now available from the Pixel Ebay store for $157 a set, and they should start reaching stores and Amazon etc shortly (around $145 a set).

    This is exciting if you are a Nikon shooter. Will be looking forward to the full review.

    This aspect is a bit disappointing: No individual FEC adjustment for flash on Camera (camera set FEC works but adjusts all groups)

  2. Author
    Flash Havoc 7 years ago

    Hi MRomine,

    That FEC adjustment may actually be different with the Nikon version. I’m not that familar with Nikon, but I have noticed Nikon cameras handle FEC differently to Canon. So I will have to wait for more detail on that one. Thanks.

  3. Branko 7 years ago

    Any idea why i-TTL and TTL support are both mentioned on the website (besides M)?
    Is there any chance this trigger will allow for remote manual power adjustment of older Nikon Speedlights, like the SB-25/26?
    I know CLS / i-TTL will not work with the older flashes, but remotely setting the output power would be a great feature, currently only offered by the RAdiopopper Jrx, if I am not mistaken. The Jrx uses the TTL “squench” pin for this.


    • Author
      Flash Havoc 7 years ago

      Hi Branko,

      I’m not sure about the website, but they definitely allow remote manual, and they can mix TTL and remote manual groups.

      Sorry no, they would need the quench pin system to work with older speedlights as well. As you mention its only the JrX that uses that system. Since the SB-900 onward no longer support quench pin, the trigger manufacturers are mainly focusing on later flashes now. They are well aware of it, but obviously not interested enough unfortunately. Thanks.

      • Branko 7 years ago

        Thanks for the quick answer.
        I was already afraid of that. I guess it will be slowly time to replace my SB25 and 26 with some (used?) SB6/7/8/900 besides my SB800…

        • Author
          Flash Havoc 7 years ago

          No worries, well Pixel will likely have their own flash at some stage too. Though no word on that as yet, and the Nikon version would likely be at least a little behind as usual.

          But still something to consider as that would be less receivers.

        • Branko 7 years ago

          The Pixel King Pro will trigger my SB-25 and 26 in manual mode, wont’t it? Without remote adjustment, just firing it.
          And I could mix that in with remote manual adjustment or i-TTL operation of my SB-800?

          • Author
            Flash Havoc 7 years ago

            Yes, they will fire the SB-25 and 26 no problems, and mix in remote control with the SB-800.

            King X receivers would do there (or even previous King receivers).

  4. Bob 7 years ago

    Can the King Pro use the Nikon CLS menus like the Aokatec AK-TTL ?

    • Author
      Flash Havoc 7 years ago

      Hi Bob,

      Sorry no, the King Pro only uses its own interface. Thanks.

  5. Branko 7 years ago

    OK, I know I’m pushing it, but has anyone tried a Yongnuo 622 with the Pixel King Pro on top?
    Why would one do that?
    – AF assist on the 622
    – use the interface of the Pixel King Pro, no digging into the camara’s menu, no need to use the 622 “blindly”
    – a set of 622s is roughly the price of one extra Pixel King receiver
    If the 622 can read the communication between camera and a SU 800 or any SB in master mode, and the Pixel King is -at least for the camera- compatible with the Nikon SBxxx’s, it could work in theory, couldn’t it?

  6. Rick 7 years ago

    Does anyone know if Pixel King Pro will work on D40? D40 does not have a commander function, so it can’t trigger a wireless flashgun on its own. I was thinking of buying SU 800, but Pixel King Pro is cheaper and has wider range, except that I don’t know if it can only work with a camera with commander function.

    • Author
      Flash Havoc 7 years ago

      Hi Rick,

      You generally don’t need a commander for the King Pro to work, but the D40 is not listed as compatible on the Pixel website so I’m not sure. Hopefully someone who has tried this can give you a better indication. Thanks.

  7. SB 7 years ago

    I have an issue with these triggers.
    The flash power is set in manual mode to 1/4.
    If the ISO value is changed on the camera (100-6400) I get the same light output from the flashes. I tested this with D90, D600, D700.
    This can’t be the way the system is supposed to work because this makes no sense.

    • Author
      Flash Havoc 7 years ago

      Hi SB,

      I don’t have the Nikon version to try this, but this is the first report I’ve had of an issue like this.

      I can’t imagine other people would not have noticed this, so I’m not sure what to make of it. Hopefully some other Nikon users can try this and let us know if they are seeing the same result.

      They definitely shouldn’t be working like that in manual though. Thanks.

      • SB 7 years ago

        I just restored all my gear to factory defaults but the problem is still there.

        • bq 7 years ago

          I’ve had this similar issue and emailed PixelHK about it a while back, what I wrote:


          I have a set of your Pixel King Pro/X transceiver/receiver units (for Nikon) and am noticing an issue with the light output when I set the power to 1/1 via the Pro’s UI. The light output, when controlled with the Pro is lower than if I manually set the flash to full 1/1 power and fire via Nikon CLS. I have reproduced this issue with a Nikon SB-700 and SB-600. Are you aware of this issue, and if so, do you plan on releasing a firmware update to resolve this issue?”

          This was their response:

          “Dear Sir,

          Thank you for your email!!
          Can you please kindly to advise which camera model you are using?

          Please try to do this way:
          Before you insert the flash to King X, please kindly to set the flash as TTL mode.
          Then insert t King X.

          After that you set the M power on the King Pro manual.

          See is it the same result you got before.
          Can you please also send the result picture for our reference?

          Thanks and best regards!

          Pixel Technical Support Team”

          I tried the steps that they advised and haven’t ran into an issue of flash power since.

          The only other issue that I know about but am not sure if it is the same for other flash triggers is: when I take a photo, adjust camera settings, then take another photo. The 2nd photo will have misfired. SB, let me know if you are experiencing the same thing.

          • Author

            Thanks bq, that’s an interesting solution.

          • SB 7 years ago

            Thank you, BQ! The problem is still there, tried every possible scenario, I even installed an old firmware on a set of the triggers. I don’t understand why this is happening because the cameras and flashes where reseted to factory defaults.

            Do you experience this issue with your triggers?

  8. bq 7 years ago

    SB, I have not. I am running the latest firmware on both the TX and RX units though (v104).

  9. bq 7 years ago


    I finally had the time to test out my triggers and have successfully reproduced your issue. It definitely seems like the firmware acts as though the triggers are still in TTL mode when the ISO is adjusted.

  10. bq 7 years ago

    OK, here is an update for anyone with the issue that SB mentioned. I contacted PixelHK support with this:


    I am having a problem with your Pixel King + Pixel X Nikon units. Attached are images that will provide you with an example of my problem. It seems as though the triggers think they are still running in TTL mode when I adjust my ISO. I have two pictures, one shot with ISO 100, Pixel King set at Manual 1/16 power, on an Nikon SB700 set to TTL. The second picture is with all the same settings except at ISO 1000. I am currently running on v104 on both Tx and Rx units. I would think that the exposure on the picture shot at ISO 1000 would be a lot brighter. Please let me know your thoughts. ”

    PixelHK Support responded with:

    “Indeed, for the time being, our flash trigger can’t read the ISO value.
    So the change of ISO value doesn’t make any influence on our flash trigger.
    We guess that why you get confused. Sorry for that.

    But we already report this issue to our R&D center. We will try to make improvement to figure out this problem.

    Should you have any questions, please let us know freely.”

    • Author
      Flash Havoc 7 years ago

      Thanks bq.

      Well that is certainly an interesting outcome. I’m really surprised its taken this long for anyone to notice.

      So we will just have to look out for firmware updates to see if this gets resolved.

      Sorry to hear about the issue, but thanks for letting us know.

    • SB 7 years ago

      Thank you, BQ!

      I also got an e-mail from them but it doesn’t make any sense

      “Dear Sir,

      Sorry for that late to reply your e-mail!!
      After we showed the image to our development team, we know this is a bug on our trigger.
      Basically our King Pro TTL system is not the same the Nikon TTL system.
      We just write our own system to let the King Pro control the flash value, but our development team is hard to get all the data with ISO change from the camera.
      At this moment, our King Pro will not change the flash value if you adjust ISO on the camera.
      But we will try to solve this problem later.”

      They are stating here that:
      “At this moment, our King Pro will not change the flash value if you adjust ISO on the camera.”
      but the exact opposite is happening.

      Now I’m stuck with three sets because I didn’t saw this earlier 🙂 I hope they will really fix this.

  11. Matt 7 years ago

    Hi SB,

    I cannot reproduce the problem with version 1.04

    Nikon D7000

    – SB-800 in iTTL on King X (as per manual)
    – Camera set to Manual exposure for example 1/100th sec. f 3.5

    When I then only change the ISO on the camera the results are as expected.
    I noticed that the SB-800 even shows the changed ISO on it’s display correctly.
    This means, that for my combination, the King Pro does read and transmit the ISO correctly.

    I might try with an SB-600 too when I have the time.



  12. Matt 7 years ago

    …just tested, the SB-600 work fine as well.

    • Author
      Flash Havoc 7 years ago

      Thanks Matt,

      It looks like the issue is with some camera models and not others then. Thanks.

    • bq 7 years ago


      Can you please try the following settings?

      Case A)
      Full Manual on the D7000 with ISO100, f/3.5, 1/250s (Or any setting to rule out ambient light)
      SB600 set to TTL + FP + Pixel X on Channel A
      Pixel King Pro set to Channel A @ Manual 1/16 power [auto] zoom

      Then take a picture of the flash, head-on.

      Case B)
      Same exact settings as Case A, except changing your ISO to 3200 (using a relatively large sensitivity gap to rule out any doubts)

      Take a picture of the flash again, head-on.

      If you compare the histograms of both case A and Case B, you will notice that they are very similar. The only difference being more ambient light and noise on Case B. The expected result of a properly working trigger would result in two totally different histograms, Case A being pushed more left than Case B. However, the results that I and SB have been getting is that the flash units seem to reduce power as we step up the ISO, and increase power as we step down ISO. This would indicate that the flash units are acting as if they were stuck on TTL mode, and not full manual power – as manual power would leave the flash units’ power constant at 1/16 in our test case.

      They have admitted that they are trying to resolve this issue, but as of now the ISO issue is somewhat of a deal breaker. The workaround would be to set manual power settings on the flash units themselves and just use the Pixel units as wireless triggers.

  13. Matt 7 years ago

    Hi bq,

    that’s the way I did it, but with 1/64 and 3 pics (ISO 800, 1600, 3200).
    I kept framing the exact same object and didn’t change the zoom position etc.
    Used a constant aperture lens anyway.

    What do you mean by head-on?


  14. bq 7 years ago


    I mean to point your lens directly at your flashbulb. This is a very interesting situation to me because our gear is identical, given the test cases above. I’m shooting with a D7K, SB600, and the King Pro + X on v1.04. The only other thing that might be different is the camera’s firmware as I have not heard anything about upgrading the SB600’s firmware.

  15. Matt 7 years ago

    Hi bq,

    I don’t think that the firmware can be changed/upgraded on the older speedlites.

    The only thing I can think of is different might be how we use it.
    I understand that the speedlites must be set to TTL in order to work correctly.
    This is ok, because if you want to control the flash power manually, then this is set exclusively on the King Pro, NOT on the speedlite itself.

    I use them in the following way:

    Assure that the speedlite is set to TTL already:

    1. Take the bare SB-600, switch it on and set the mode to TTL.
    2. Then switch it off again.
    3. Usually you would never have to change this again if used with the Kig Pro/X

    General Usage:

    1. Camera, SB-600 and King Pro/X are all off
    2. Mount the King Pro onto the camera
    3. Switch on the Cam, then switch on the King Pro
    4. Mount the Speedlite onto the King X
    5. Switch on the King X, then switch on the SB-600
    6. Set the desired flash mode only on the King Pro

    Hope this helps,


  16. Joseph Farrugia 7 years ago

    The Nikn version of the PKP is NOT YET READY……please urge Pixel HK to release a firmware upgrade (beyond v1.04) to fix the erratic iTTL output & non working Manual mode.

    I am changing TTL & Manual power settings on the PKP itself not my D610. Changing exposure compensation (I have it set to global, not just ambient on the D610, custom setting e4) on the camera has ZERO effect on the output in TTL mode on the PKP (what a pity!).

    —->TTL is inconsistent even with known targets like a CC24 chart in front of a Lastolite Gray balance card, but at least I’m able to change ISO on the camera & the exposure shifts only marginally. I am using various SB-800 flashes on PKP Rx.

    But the PKP(ro) set to Manual (eg: 1/32, etc )with my various SB-800s (all on TTL on a PKP Rx) & my D610 & S5 bodies……a nightmare. Manual mode WITH the trigger is always always always underexposed when compared to using optical triggering of the flashes (ie WITHOUT using the PKP)………and……wait for this……at any given PKP Manual flash setting (eg: 1/32 power), changing the ISO (on camera of course, you can set ISO on the trigger) gives………the same exposure!——-> for example: I set up a scene for 1/32 manual power at ISO 100 on the camera, change the ISO to 1600……& the image is still exhibiting the same brightness, meaning the PKP receiver somehow put out way less power in the 2nd ISO 1600 shot to compensate. (4 stops over ISO 100, the image should be blindingly bright)

    in TTL mode I have to dial in +2 ev as a base on the PKP, otherwise the image is underexposed. This can easily be confirmed by putting the NEF through an “honest” raw converter lie RPP, or through the free Rawdigger software: the images in TTL ARE indeed severely underexposed when using the PKP. If the subject is light & usually needs for eg. +1.3 EV, I have to dial in 3.3EV on the PKP. But at least the PKP is somehow (sometimes!) aware of changes in the ISO when using it in TTL mode.

    Flashhavoc Nikon readers should be advised, otherwise like me they’ll be shelling out hard earned cash for a half-baked, not-yet-ready product without knowing its limitations.

      Hi Joseph,

      Thanks for the feedback. The ISO issue is being discussed in the comments above yours.

      And I have added a note to the post so that people will be aware.

      If you read through the discussion above it may be of some help. Particularly the part about setting the flash to TTL before placing on the receiver.

      The underexposure issue your seeing doesn’t appear to be widely reported as yet. Pixel obviously still have some work to do with the Nikon version of these though. Thanks.

  17. Carlos 7 years ago

    Ive got a new pixel King Pro for Nikon. In the first minute the lcd panel lost the lines, the numbers and all the information. I Switch it of and then… I switch it on and the information is now on the panel, but again using some buttons disappear again display information, while still lit.
    I put on the firmware 1.04 but it is still failing.
    Sorry for my poor english, I hope somebody understand me and can give me some help soon.
    Thank you very much.
    (another thing is: I cannot use my light meter because using the pixel king pro out of the camera gives different measures when making with it placed on the camera) (Is there a method for measure with the test flash shutter botton out of the camera?)

    • Author
      Flash Havoc 7 years ago

      Hi Carlos,

      It definitely sounds like you have some faulty units with the LCD display like that.

      Even if they worked properly now for a while, I wouldn’t like to take the chance that the issue will return again when you need the triggers to work. So they will likely need to be returned.

      It could be something simple to do with the battery contacts, or even possibly the ON / OFF switch etc. But it may be hard to find the issue.

      Considering the other issues in the comments above, you may even be better off just returning them and getting the YongNuo YN-622TX / YN-622N. Or better still the Phottix Odin (provided you are using Nikon flashes).


      Regarding the light meter reading. Yes this is a known issue. Because the slave flash is set to TTL there will always be a pre-flash which confuses the meter. The only way around this is to try and separate the pre-flash from the main flash.

      One way to separate the pre-flash has been to use the Mirror Lock Up. Please see this explanation posted regarding the YongNuo triggers which have the same issue.

      The Phottix Odin have a delay of 2.5 seconds between the pre-flash and main flash, when pressing the Test Fire button. This is designed to allow for this light meter use. Thanks.

      • Carlos 7 years ago

        Thank you very much for your quick reply. Also thanks for the website.
        A little something:
        1.- Please, is there a transceiver and receiver (for nikon) that can be used in M or TTL with a light meter? I mean to use it outside the camera and able to handle manual or ttl mode with the transceiver from the position of the subject. The pixel king pro cant’t do it. (I try what you say… but dosent work) (nikon D7100. sb700)
        2.- I also need to shoot with the same transceiver and receivers with other camera that it is not nikon. I know that then I lose ttl and all the other controls, but I dont care, I would only need to fire the flashes, because I supposed can handle any flash from the flash itself. Pixel king pro cant,t do it. It will not fire the flash with other camera (sony nex 6)
        any recommendations?
        thank you very much. (sorry for my poor english)

        • Author
          Flash Havoc 7 years ago

          Hi Carlos,

          A light meter can’t measure TTL. But then there is generally no reason to measure TTL, because TTL is automatically flash metering with the camera.


          For manual with a light meter the Phottix Odin will work, but the Odin transmitter can not be used on NON Nikon cameras.

          So the PocketWizard TT1/TT5 and AC3 Zone Controller are the only TTL triggers that can do this (with Nikon). You can even use the remote manual power levels when using an NON Nikon cameras.

          The PocketWizards even have a Sekonic radio module built-in, so you can fire the flashes straight through the meter.

          And even more than that if you use the Sekonic L478DR flash meter you can also change the flash power levels directly through the light meter!

          The PocketWizard system is obviously not cheap though, and some people have not had good reliability with the ControlTL triggers. While others are quite happy with them.


          • Carlos 7 years ago

            (Yes, I know that I cant measure with TTL with a light meter. But in manual mode it is important, for me)
            I will try to buy the pocket wizards and the sekonic. Very expensive.
            (Just right now I am using the small Elinchrom triggers, of course in manual mode, with vivitar 285hv flashes (using hardly these from 24 years ago, and they are still working) This year I was thinking to change,(that’s why a buyed some pixel king pro) and get more flashes(Nikon SB-700) to play and take my pictures in the TTL way. Of course I dont want to forget the manual mode, because this is the way I know to do the things, and I need to measure) Im sure that if I embarking with the last technologies, my bag catch much more weight, and more things will be able to break. Scared, because many things I buy new; stops working soon. If something stops and the things do not go well…then, the client do not call again. Every job is a test.
            I will try to get the PW and the sekonic (Dont know… its a lot of money and living a crisis) and leave my old sekonic, my old vivitars and all my old stuff (but all very safe and reliable) in a showcase.
            Thanks a lot and sorry for my poor english.

              Hi Carlos,

              Maybe you could consider a separate simple remote manual system as well. The Godox V850 are very simple, convenient, reliable, and inexpensive. The transmitter will work on any camera with a standard shoe.

              This whole system with 4 or 5 flashes cost less than a single pair of TT5 and, they are more simple and reliable.

              Maybe get some Phottix Odin for the SB-700 as a separate system just for the Nikon camera and when you need TTL. Thanks.

    I’m confused about metering. In the above comment you say you can’t meter the flash because there’s a pre-flash. But in the ‘full’ (Canon) review you say you can meter. What’s the truth?!

    Assuming here I want to shoot manual power flash, not TTL. as far as I know the Canon and Nikon flashes both pre-flash in TTL but not manual modes.

      Hi Flash Gordon,

      The Canon and Nikon version differ in this respect. With the Canon version the flash actually changes modes. So when using remote manual, the flash will actually change to manual mode (and the manual power levels will be displayed on the flashes LCD). So there is no pre-flash in Manual mode on the flash.

      For Nikon most TTL triggers have had to take over the flash in TTL, and then set pseudo manual power levels (through a TTL power level the transmitter has set itself to match the regular manual power levels). So the pre-flash is always there.

      This is the same with YN-622N and Phottix Odin. Phottix Odin even use the same method for Canon as well.

    Hi – I just set up the King PRo for Nikon. Updated the firmware in Tx and Rx to 1.04 all around. With Nikon D4 and D700 TTL and manual flash EV adjustments work as they should. With D90 EV adjustments in both TTL and Manual change the shutter speed on the camera. Any idea why?

  20. Bob 7 years ago

    My mistake!…the D90 was set to bracket…duh…all is well…this is an excellent TTL and manual flash product…

    Hello, one question, please.
    The power pixel king plus seems that is dosent work when I change the iso on the camera. I ve got under (100iso) and over exposure (400iso and above). Only works on 200iso.
    – Any solution?

      Hi Carlos,

      This issue is mentioned in the comments above. Unfortunately I don’t think there is much you can do until a firmware update is available to rectify this. Thanks.

    I’m having some strange problems with my king pro/x and my flashes when used on a D800, I was hoping somebody with similar equipment could replicate them and figure out what’ wrong.

    First of all, I tried this with a SB700, a Metz 58 AF-2 and a Meike MK-910, the problem occurs with all three of them.
    When mounted directly on the camera, all three flashes produce consistent and accurate exposures (in TTL mode).
    The same holds true when I swivel the flash head to face backwards or upwards (bouncing the flash on the ceiling or a wall behind me).

    But, when mounted either on the TTL pass through on top of the King Pro on the camera, or on a remote king X, all three of them produce severely underexposed shots when the flash head is turned anywhere but the default position.
    The same thing happens in all shooting modes, with both auto and fixed ISO, as well as A,S,M modes on the camera.

      Pixel has a new Firmware (1.05) in the making for this, which will be released soon.
      I tested an early version which solved the exposure problem, but was not stable yet.

        Ok great, thanks Matt.

    Be careful with that version. For me, it really does not work. Fault ttl mode. Not able to control the iso. If you change the iso, the exposure is incorrect and that does not happen with previous versions. If you change the iso up… you get overexpsure and if you go down you get underexposure. I install the firmware V1.05 two or three times ande always the same. I have to put back the v1.04.

  24. carlos 6 years ago

    I remember that some people says…. when in manual mode and change the iso up;, there is no more light coming in from the background. (Sorry I dont speak well english) or if you go down there is no less light coming in.
    I have found that the cls system does the same with the flash on the camera without using the pixel pro nikon. Another thing is using a flash with a separate cable ttl from the camera (also without using pixel); now, if you change the iso up or down with the same speed and f… the exposure is changing.
    Again… sorry for my poor english.
    If you do test with:
    pixel king pro king, Manual and ttl, changing the iso.
    without pixel king pro and only using the cls sistem, Manual and ttl, changing the iso.
    with cable ttl without pixel king pro. Manual and ttl, changing the iso.
    you can see the diference.

    What did I need with a new firmware is some way to measure in manual mode with a light meter standing in the position where the light is going on.

      Hope someone can help. I’m using a D800 and SB800 with the PKP and X. The main issue I have is in manual control from the PKP the SB800 fires at about half the power that the flash fires when set in manual and fired. The output does change when adjusted from the PKP but the output is about 1/2 the flash power. I get the same results with an SB600 and when using a D7000 with either flash. Also, the v105 firmware would not work for the SB800 with either camera but did with the SB600.

    Flash Havoc: I previously wrote on your page discussing the problem with Yongnuo’s YN-622N-TX system and how it doesn’t perform Flash Value Lock properly, I’m now wondering if Pixel King Pro performs Flash Value Lock properly. Specifically, I’d like to hear from anyone who has tested Pixel King Pro and Flash Value Lock on Nikon. . . who absolutely positively understands what FVL is and how it’s actually supposed to work. Thanks.

      Hi Mike,

      I’m not sure about the FVL, but if you read through the comments above there are still a number of issues to be resolved with the King Pro for Nikon. So you’d want to check that those are not going to be a deal breaker either.

      YongNuo likely understand your issue with the YN-622N-TX, they are likely just busy with other things to resolve this at the moment.

      • Mike Lubchenko 6 years ago

        Yongnuo hasn’t given any indication they understood what I was talking about, in fact several of their replies (when they bothered to reply) indicate they misunderstood. The closest I got was when one service rep said my information was being passed along to the technicians, however when I followed up a month later their response was back to indicating they had no idea what I was talking about.

        Re: Pixel King Pro. At least Pixel seems to be quicker about fixing problems and releasing firmware updates than Yongnuo. Unfortunately, from what I can tell so far, Pixel King Pro’s do not work at all with Yongnuo’s YN-568EX flashes (I have four), so if I want to dump Yongnuo’s transceiver system it also means buying new flashes. Then I’m looking at a big loss reselling the transceivers, and another big loss if I have to sell the flashes, and then even more money to buy replacements for everything. That’s part of why I want to be absolutely sure that if I get a replacement system, everything actually works as advertised. At the same time, I can’t really afford Pocket Wizard or high-end name-brand flash units, at least not now. I suspect I’m screwed.

    HI FH
    I registered to post two days ago but have not had a confirmation email as yet 🙁

    I generally always shoot in M mode; however on occasion I may shoot using one of the Auto modes
    I have a kit of Phottix Strato II Tx/Rx but there are three features missing

    a) the ability to remotely change flash output when the the flash is in Manual and the camera is in Manual
    b) using several off-camera flashes in iTTL via radio transmitters (when shooting run&gun)
    c) using a camera mounted flash PLUS several off-camera flashes in iTTL via radio transmitters (again when shooting run&gun at say corporate events)

    Will the Pixel King Pro fulfil my needs ?

  28. Vince 5 years ago

    I use a Sekonic L758DR meter. To acquire proper light exposure when shooting portraits,or studio imaging, I place the meter near the subject and using my remote radio trigger a test flash to which the meter indicates proper aperture and shutter speed. I,m sure you are familiar with this procedure. I,m going to purchase
    a set or two of the Pixel King PRO transmitter and receivers. My concern with this system how do I go about creating a pre flash from each flash when I,m by the subject with no means of triggering the flashes with the King Pro transmitter on the camera which is on a stationary tripod for a needed shot. I,ve tried to come up with an alternative approach but seemed to be left with no resolve. If there is an procedure I,ve overlooked a response would be greatly appreciated. Thank you Vince

    I cannot even get a firmware update, to work, with the Pixel King Pro transmitter. Once I copy/paste the new BIN file, into the “CDP DISABLED” drive, on “My Computer”, the icon stays red, and about 95% across the strip. (It never goes to 100%/green.) Anyone else have this problem, updating firmware? Help!

    Good day. I know these transmitters are old, but I know they are 2.4GHz. I’ve used them with my Nikon SB-800 and they work nicely. I just bought a Flashpoint XPLOR 600, which is also 2.4GHz. Does anybody know if these Pixel King Pros will work with the XPLOR 600? Thank you.

      Hi Darrell,

      They won’t communicate directly with the radio receiver inside the XPLOR.

      You could attach a King Pro to the strobe as receiver unit, though that would only fire the flash, and provide the HSS signal (HSS needs to be switched on manually on the strobe), no remote power control or TTL etc.
