FLASHPOINT R2 PRO-C / GODOX XPRO-C – TTL Transmitter Announced


Flashpoint have announced the very much anticipated R2 Pro / Godox XPro-C, TTL and HSS enabled transmitter unit for Canon DSLR’s, and they are available now from Adorama for $69.00.

With Nikon, Sony, Olympus/Panasonic, and Fuji versions to also roll out over the remainder of 2017.

With a large clear dot matrix LCD screen displaying all 5 groups at simultaneously, and individual dedicated groups buttons, the Pro transmitter provides a huge improvement over the previous R2 / X1 transmitter’s user interface.

Very likely the biggest improvement for users to the compatible Flashpoint & Godox 2.4GHz flash system to date.



  • Large Dot Matrix LCD Screen Displaying 5 Groups
  • 5 Individual Dedicated Group Buttons
  • Display Zoom – Displays One Group Larger with More Details
  • TCM Function – TTL – CONVERT – MANUAL
  • Flash Head Zoom Control Interface – by Group
  • Modelling Light Control – by Group (Currently On /Off Only)
  • Global Adjustment of Group Power Levels (ALL Button)
  • Large Graphic Menu System with Multiple Custom Functions


Flashpoint R2 PRO - Godox XPro-C


The Pro transmitter now provides the option of working with up to 5 groups of lights – A / B / C / D / E, in a mixed Group Mode style environment, where TTL and Manual groups can be mixed together, and individual groups can easily be switched On and Off.

NOTE – Pre-2012 cameras only allow TTL in groups A, B, & C. Groups D & E are manual only.

As well as the option of controlling up to 16 Groups in Manual mode (A-F & 0-9), corresponding with the older XTR-16/s style radio receivers.

With dedicated individual group buttons, adjusting each group is now very simple, fast and intuitive.



And for people that may still prefer the XT-32 style single group display, at the press of a button the Pro transmitter provides the option of switching back and forth from multiple group display to a larger single group display showing more details.

  • Powered by 2 AA Batteries



Another significant feature now provided with the Pro transmitter is the new TCM function.

TCM stands for TLL – CONVERT – MANUAL.

This is Godox and Flashpoint’s version of Hybrid or Fusion TTL, where its now possible to take a shot in TTL mode to attain a correct exposure very quickly, and then at the press of a button convert those TTL power levels to now display on the transmitter as Manual power levels.

The manual power levels can then be further refined, and provide consistent exposures for further shots in the same set up and environment.

The TCM function is potentially a huge advantage for people operating in a fast paced environment, allowing a base setting to be gained very quickly without manually metering lights. Switching to manual the individual power levels can then be refined as needed, and exposures remain constant for subsequent images.

Flashpoint R2 PRO - Godox XPro-C


Other features include a flash Zoom control screen, and a large graphic menu with custom functions –


Flashpoint R2 PRO - Godox XPro-C


The Pro transmitter provide similar range and reliability to the original R2 and XT transmitters, and also currently use the same AF assist light, and regular screw locking foot.


Flashpoint R2 PRO - Godox XPro-C


A shutter release function is provided, as well as a Type-C USB port for firmware updates, and a 2.5mm sync port.

And the Pro transmitter is once again powered by 2 regular AA batteries.

Flashpoint / Godox – System Overview


  1. Richard 4 years ago

    Been using this unit (flashpoint version) flawlessly on my 6d (original) however I just received the 6dii and it doesn’t seem to communicate on TTL mode. Any one else experiencing this problem? FYI, I’ve updated the x1 trigger to the latest firmware and it works on the 6dii? Perhaps this unit needs a firmware update?

    • Martin saxon 3 years ago

      While im not uing the same equipment as you, I only today noticed something similar. Im operating a Sony a7r3, xpro-s transmitting to a Ad360ii-c
      In TTL mode on the transmitter you can adjust the exposure compensation from -3 to +3 but it does not relay that to the flash. All other functions appear to be working.

      • John Wilson 3 years ago

        This is apparently the intended behaviour. The trigger applies the flash exposure compensation locally and sends the resulting value to the flash. If you set the flash exposure compensation on the flash it then applies that to the value sent by the trigger.

        e.g. if the trigger is set to apply -1 stop to group A and there are two flashes in group A one has the FEC set to +1 and the other to -1 then the first flash will have an effective FEC of 0 and the second of -2.

        Not all Godox flashes do this. My TT350F sets the FEC to 0 when in remote TTL mode and I can’t change it.

  2. Mike 4 years ago

    One question I can’t find an answer to.. does the R2 Pro have a “PC Sync” input? It seems like a silly thing to use, but one of my film cameras only uses PC Sync output to connect to strobes; I tend to switch the transmitter from DSLR to the film one to use the same settings. Currently the X1T works great for this.

      Hi Mike,

      Yes the Xpro has a custom function option to change the sync port to input or output.

      Its a 2.5mm sub-mini phone port though in the transmitter, not PC sync.

  3. Jesse Patterson 4 years ago

    I see that in order to control the zoom of my V860II flashes from either the Godox XPro-C or the X1T-C, I’ll need to leave the flashes in auto-zoom. Since the manual-only speedlites don’t have auto-zoom, does that mean I can’t adjust the zoom from the Godox Xpro or the X1T? I realized this when I tried to control the zoom settings on my TT600s and V850II.

  4. Seamless Media 4 years ago

    Is anyone having issues with misfires? I see the manual recommends using alkaline batteries, I’m wondering if using the enloop pro’s are causing the problem with the 1.2v vs 1.5v operating voltage. Even when fully charged the battery level on the XPro starts at 1-2 bars. Why couldn’t they have foreseen people wanting to use rechargeable and auto adjusted, or made a menu selection for battery type?

    • the flasher 4 years ago

      I totaly agree with you….

      I only use rechargeable AA batteries in my electronic equipment because they don’t end up leaking if you leave a device accidentally turned on. Over the last 20 years leaking alkaine batteries have damaged various triggers, flashes, microphones and magic mice.

    • Pete 4 years ago

      The manual says that 1.5v alkaline batteries are to be used and it’s now common knowledge that using 1.2v definitely affects the battery display (in that fully charged 1.2v batteries show 1-2 bars) but many people are commenting on misfires and other funny stuff happening and it may be down to the differing voltage. I used to see similar issues with misfires and TTL not working correctly with Yongnuo triggers and switching back to Alkaline sorted it. However, as the flasher says, leaving alkaline batteries with a low drain device like a trigger is a bad idea so the best solution is to use Lithium batteries such as Energizer Lithium AA’s as they dont suffer from the same problem. I dont get any problems with misfires or other stuff with either my X-Pro or my XT1-T using Lithium batteries.

    I recently noticed that a speedlite attached to a X1R-C receiver still fires even when the assigned group is disabled on my XPro-C flash commander. Obviously, this is not the expected behavior.
    When the assigned group is active, the flashes work as requested (either TTL or manual).
    The camera used is a Canon 550D. The issue appears with both a YN568-II and Canon 580EX2 speedlite.
    Both Xpro commander and receiver have their latest firmware.
    I also noticed that when disabling the group on the Xpro-C, the speedlites are then set to M mode, at 1/128 power, rather the simply not firing the flash at all ?
    I also have 2 x TT685C, and these behave properly (controlled directly, no additional receiver). They don’t fire when their group is disabled on the XPro-C.
    Any ideas (firmware bug in receiver ?)



  8. Jordan 4 years ago

    I cannot find this information anywhere on the internet – I have a Canon 5dM4 camera, the R2 600 Strobe, and this R2 Pro-C trigger. I cannot for the life of me how to use second curtain sync with this thing. I set all of the flashes to manual, set the R2 Pro to second curtain sync, use a slow shutter of 5+ seconds, and the flash never fires at the end of the shutter closing… anyone know how this is done!?

    • Author
      Flash Havoc 4 years ago

      Hi Jordan,

      I just checked with my 5DIV, R2 Pro-C & XPLOR 600, and the second curtain sync is working fine.

      Do you have the second curtain sync working with a Canon flash, or any others?, as maybe there is a camera setting somewhere which can disable it.

  9. Noel Harvey 4 years ago

    I want to use the XPRO-C as a wireless shutter release.

    According to the manual, with X1R-C connected to the camera,

    Half press of button to focus , and full press of test button to release shutter.

    But when I half press button, it fires the strobe, and when I full press the button , it focuses and releases the shutter.

    This is no use, because the strobe fires independently of the shutter release.

    Here is Youtube video of problem:

    Will this transmitter activate the Canon Speedlite 600EX RT II?

  11. andy 4 years ago

    My XPRO-C misfired frequently. I shoot with Canon 5D III and AD600, Manual mode on camera f/5.6 , 1/200, ISO 400, and power 1/16.

    Here is the problem – If i keep shooting non-stop, it’s ok, but if i stop for may be 10 sec, then it misfired! I have to press test button on the XPRO-C to activate trigger again. I’ve never changed anything on custom functions or anything like that.

    Anyone has any idea of what’s going on ? or my trigger is faulty? I guess I have to ask Adorama too. Last night was very frustrated and I have to keep asking clients to wait….shame.

      Hi Andy,

      Somethings not right there. 10 seconds is not long, so the transmitter is not even going to standby yet?

      Does the camera symbol show at the top of the transmitter when you half press the camera shutter?

      Also did you try doing a reset (hold the center 2 menu buttons together).

    • Michael Pick 4 years ago

      i am having this problem, with old godox trigger and new one.. i have tried them on 3 bodies, same problem

  12. Andy 4 years ago

    Hi Flash Havoc,
    I actually looked at the XPRO-C custom function last night. The “STBY” is set ON. I set it to OFF. I will try again at photo shoot next weekend. So far, right now, it seems to me there is no misfired.

    To answer your questions:
    1. Yes, it’s not really that long for Transmitter to go standby mode. Right now trigger is Ver 1. I think there is firmware update to provide better standby adjustment.
    2. I’m not sure what you mean “Does the camera symbol show at the top of the transmitter when you half press the camera shutter?” I don’t see any Camera symbol.
    3. I’m not trying to reset. Since the flash did not fire, I just tapped test button (the one with flash symbol) once or twice until flash fired, then I started pressing shutter release to shoot.


    • andy 4 years ago

      I’d like to follow up your questions:
      2. Yes, I see the camera symbol when half press button. Does it mean anything?

  13. andy 4 years ago

    One more thing I forgot to mention. I was shooting tether to laptop Lightroom CC with USB cable.

    • Author
      Flash Havoc 4 years ago

      Hi Andy,

      Tethering may be adding something to cause the issue.

      Though firstly as you mention, you want to update the firmware to the current V1.4, because there is something mentioned regarding the standby function. (I wasn’t aware of the issue that’s addressing otherwise).

      When I say to reset the transmitter, that is to help clear out any possible errors that may have crept into the functioning. Like rebooting your computer etc.

      The camera symbol on half press of the shutter just shows that the transmitter is recognizing and communicating with the camera. If it wasn’t showing up, then it would be more obvious when your going to have an issue.

      I would do the firmware update first and see how that goes. Though maybe you do still need to turn the standby mode off when tethering as you have now.

      • Andy 4 years ago

        Thanks Flash Havoc. I didn’t realize XPRO-C use USB-C which I have just ordered the cable. Will update new firmware when cable arrives.

  14. Harald 4 years ago

    Does anyone know if the Xpro can trigger the old Godox FC-16? Are they somehow compatible? (I have several old speedlights that I want to use in a setup being triggered by the Xpro – of course manually, a remote control function is not needed because the old speedlights are of different manufactures and provide pure basic functonality. So i am just looking for a cheap solution to trigger these old speedlights in my setup) thanks 😉

      Hi Peter,

      Misfire issues with the Canon Xpro are not common.

      Are you using Alkaline batteries (Energizer or Duracell) in the transmitter?, as their higher voltage than rechargeables provides a stronger signal.

      Hi Eduardo,

      I’m not too sure, though the 550EX and 580EX are pretty old flashes, so its likely that is normal unfortunately.

      From the 580EX II onward you should have more compatibility and control.

  18. Brendon 4 years ago

    Hi I was wondering what receivers I will be able to use that are compatible with the XPro to trigger my Elinchrom Lights

    • John Wilson 4 years ago

      Hi Brendon!

      Any of the X1R receivers will work. You need to connect a cable from the receiver’s PC socket to the trigger input to your light.

      You could try putting the Elinchrom trigger on the hotshoe if the X1R and see if that works. I would expect it would but I’ve not tried. That way you’d only need one X1R.

  19. Greg 4 years ago

    Bug report…

    I replied to an earlier post by Flash Havoc (6 months old) with some of this so there is a bit of a repeat here:

    In short, there seem to be a bug in the XPro (or system wide) where the result is that X1R’s will fire even though they are set to OFF in the XPro. They seem to fire at minimum power level.

    This will happen in one of two ways:
    1. If pressing MODE button when in group view, bringing up MULTI option.
    2. If changing the group on a X1R from an active group to a group that is set to OFF on the XPro.

    In both cases cycling through the modes for each X1R group to return to OFF will turn them off.
    Alternatively, setting SHOOT mode in the menu to multiple users will also work, since the OFF command will be communicated for each photo taken.

    Another problem is that ETTL with more than one group where an X1R is in one or more of the groups results in overexposure. Tested on a D70 (and a D550 to verify)

    – ETTL works fine when a single X1R is the only unit being used.
    – ETTL also works fine, for some reason, if one or more X1Rs’ are set to the same group as e.g. a V860II.
    – Using two V860II’s, ETTL works fine regardless if they are in the same or separate groups.

    Firmware used is the latest available:
    XPro – 1.4
    X1R – 1.8
    V860II – 1.6

  20. Catalin Z 3 years ago

    The Flashpoint transmitter (Xpro) will be able to double click on a group button to turn the groups on and off quickly. What about the Godox version? 🙂

  21. Andy 3 years ago

    To update my misfire issue with XPRO-C : Adorama sent me another one and I’m using Alkaline battery instead of rechargeable one. So far, it works fine, but I still get misfire once in a while (NOT often like I had before).

    Another side question: I’m going to have Panasonic GH5 and use mostly OCF manual mode. Can I just use XPRO-C with Panasonic GH5 to trigger AD200 (Manual , NO ETTL)? I just don’t want another trigger for Panasonic as I only use manual flash.


    • Author
      Flash Havoc 3 years ago

      Hi Andy,

      Thanks for the update. At least you’re making progress.

      The Xpro-C will generally still work in manual mode with other brand cameras, except some like some Fuji models which do have communication issues. I’m not sure about the GH5 in particular though sorry.

      I have asked for a real single firing pin mode (which disables the TTL contacts) in the coming Flashpoint R2 Pro II transmitter, though I’ve yet to see and confirm if that’s been implemented. If so hopefully some of these things can be added to the original Pro transmitters later through firmware as well.

      • Andy 3 years ago

        Thanks Flash Havoc.
        Hopefully they can come out manual trigger only with reduced price instead of full price from Xpro-C. In the meantime, I just XPRO-C with GH5. It works fine in manual mode but will misfire occasionally. One thing I realize that it’s so hard to slide the trigger in GH5 hotshoe until the point that I’m afraid it will break GH5.

  22. Fred 3 years ago

    What happened that means the xpro does not need the C.Fn-00 – Synchronization Delay Setting present in the X1T? Or are you just screwed if you need that setting?

    I just got an xpro-o and v850ii and in HSS mode and especially at lower powers there is a very bright band at the top of shots. The flash outputs almost full power for about 0.25 ms before stabilizing at the set power level and some synchonization delay (if I understand what it does) could delay the shutter till after that initial bright burst. Or is the v850ii faulty?

    • John Wilson 3 years ago

      Hi Fred!

      There’s generally a limit to how low a power HSS will work properly on most flashes. I believe that this is due to the limitation if the switching transistor.

      When the flash begins to fire the capacitors are fully charged. The transistor needs to fire the flash for a very short period in order to deliver the right amount of light. As the exposure proceeds the capacitors become discharged and the voltage drops which means that the transistor will fire the flash for longer to give the same amount of light. Now if you have set the power to be low the initial flashes will need to be of very short duration. If the transistor can’t switch that quickly the first few flashes will be too powerful (which gives a bright band).

      Putting a delay in will remove the bright band but give you a dark band at the bottom of the frame because in HSS mode the flash fires for precisely as long as the shutter os open.

      If you want low power HSS you can gel the flash with an ND gel (the flash will get hot so use a Rosco or Lee gel and be careful how you fix it) or find some other way of reducing the power (a scrim, for example). This lets you use a hight power setting. Or you could use a lower power flash like the TT350/V350.

      • Fred 3 years ago

        Thanks for the post but my problem is not an inherent HSS issue.

        This is the light output from the flash in HSS at 1/32 power.


        The blur for most of the pulse is the flash pulsing rapidly so take light ourput to be the middle of the blur. The initial pulse is huge. It may be faulty design, or faulty manufacture or intentional to initially warm the tube gas to bring up conversion efficiency.

        An xpro-o on Panasonic G85 captures the whole bright pulse, a very thin dark band above it and a dark band below from the dip you can see after the bright pulse. Setting second curtain sync makes no difference and there is nothing else I can change. The shutter transit time on the G85 is about 3ms so there is plenty of time in the 10ms HSS pulse to delay the shutter and not capture the initial pulse.

        I assume that is what the X1T Synchronization Delay does, delaying the shutter after firing the flash and still ask why the xpro does not need it?

        • Author
          FLASH HAVOC 3 years ago

          Hi Fred,

          I think Godox were just trying to simplify things and remove any features the didn’t think were as necessary anymore.

          I fought for it to be included again in the coming Flashpoint transmitter though so that may be an option soon.

          I don’t know if it will help your situation though. It would be best borrow an X1T-O if possible and try it.

        • John Wilson 3 years ago

          The initial pulse is large because the transistor can’t switch quickly enough to limit the current flow. It looks like the first five or six pulses are far too bright (you can see them descending in power). After that the capacitors are sufficiently discharged for the transistor to switch fast enough to control the light properly.

          It depends what you mean by an inherent HSS issue. Most lights won’t operate properly below about 1/8th power in HSS mode. The vendors could fix this by using transistors capable of a faster switching rate but that would increase the price for very little benefit. Very low powered HSS isn’t useful in most situations. If you need lower power you reduce the light from the flash by doing something like moving it away from the subject, putting a scrim in front of the flash or using ND gels.

          I think the delay was introduced into the X1 because there was a fashion a while ago to get HS (not HSS) effects by opening the shutter after the steep part of the discharge curve had passed (I think pocket wizard came up with this ploy). As all Godox battery strobes now have HSS it’s not needed. As I explained above I don’t think it would help you in this case. If you put a delay in to cut off the initial burst you will get a dark line along the bottom of the image because the flash will stop firing before the shutter is fully closed.

          • Fred 3 years ago

            Thanks for trying but I’m afraid you don’t really know what you are talking about. A 1/32 HSS pulse uses 1/32 of the power of a full HSS pulse the capacitor still has 31/32nds of its charge at the end of a 1/32 pulse.

            The more I think about it the more I think the initial pulse is deliberate to get the tube gas heated and possibly to ensure optical slaves are triggered and that the shutter needs to be delayed to avoid it.

            The HSS pulse length from this flash does not change with shutter speed. It is always 10ms. The worst case requirement is just above conventional sync speed which would be 1/200 or 5ms on the G85. I have measured the G85 shutter transit time at 3ms. So you have 3ms to open the 1st curtain, 2ms fully open dwell and 3ms to close the second curtain, 8ms total and it would take more than 2ms shutter delay to exceed the 10ms HSS pulse and produced a dark band at the bottom.

            I would not be surprised if other HSS flashes are the same and all need some shutter delay and xpo-o on panasonic appears to have none at all.

            • John Wilson 3 years ago

              Well, Fred we must agree to disagree.

              I would not be so discourteous to accuse you of not knowing what you are talking about though 🙂

  23. acha 3 years ago

    Is there any way to use the xpro to trigger a camera shutter release without a x1r? I don’t have a x1r but I do have a x1t. Do I need to buy a x1r? Or any other smaller and lighter device to use as a receiver? Thanks.

    I just received an X-Pro C and a Godox TT685c to use with my 5DMkiii. I also have a V860iiC on the way. I was under the impression that the X-Pro would be able to fire my Canon 600EXRT but I can’t make that happen. I’m thinking I didn’t do my research properly and that I would need an X1R-C attached to the Canon speedlite for it to work. Can someone confirm this for me?

      FLASH HAVOC 3 years ago

      Hi Drew,

      Yes that’s right, you need an X1R-C receiver for the 600EX-RT.

      The receivers tend to be Godox’s lower priority though as far as keeping everything compatible with after firmware updates etc, so its worth considering just going with another TT685 instead if you’re happy with those. Everything runs smoothly then, and no external receiver to worry about.

    Does anyone use XPRO-c with Canon body older than 5D III?
    Yesterday, I had photo shoot and use Canon 1Ds III. I only use manual flash. The XPRO-C seems not to be consistent with 1Ds III. I shot again the sunset, flash about 3 ft from the couple and it’s way underexposed even at 1/2 or 1/1 power. Then moved to another location, same distance from flash to subject and it suddenly was overexposed at 1/8 power!

    This does not happen to my 5D III.

    I am having very strange problem with Canon 5D mk4 and my new Godox XProC. I am using one flash for test, Canon 580EX II. Setting Global FEC and Group FEC produces differently exposed images. I am shutting in manual mode. Exposure, ISO and shutter speed is not changing

    Let’s say I set global FEC -1 and take a picture, then set global FEC -0 and group A FEC -1, with one flash this should not matter. But group A FEC -1 produces much darker image then global FEC-1.

    I also did same test with Yongnuo 622. Yongnuo worked as I expected. Global FEC -1 or group A FEC -1 produced same image.

    Am I missing some setting with GODOX or that is a firmware bug?

      Hi Michael,

      I assume you have the 580EX II attached to a Godox X1R-C receiver? I don’t think I have heard of this issue before, though it wouldn’t surprise me if it was a bug with the X1R-C firmware.

      Do you have the latest firmware installed in the receiver?

      • Michael 3 years ago

        Yes, I do have latest firmware installed in both transmitter and receiver. Also tested with previous firmware version. Same problem.

    Also, Canon flash is not working as optical master with Godox X1R receiver, is how it supposed top work?

    • Andy 3 years ago

      Michael, The X1R is radio only, so you need the transmitter, (or master flash) to be in radio master mode, to work with the X1R.
      If you are putting an off camera Canon flash on the X1R, to use with the godox system, it should not be in any master mode either.

    Can the Xpro-C be used as a Wireless Shutter Release on my canon 5D mk4? I want to be able to remotely fire my camera in bulb setting using another controller. (I have an xt32c and 2 Xproc’s). can it be done?

    Hi Nathan!

    If you buy an X1R you can use that to trigger your camera. Set it to a different channel that the trigger on the camera and use a spare trigger to fire it. However I don’t think it will work with Bulb.

    Seeing that proper remote wireless camera releases cost less than an X1R it doesn’t seem worth trying.

    I have a Sony A 6500 and a Godox AD600Pro. I also want to use 2 of my old Nikon flashes SB 800 and SB 900. I want to buy the Godox R2 Pro (for Sony) for my Godox flash. But is it possible to use 2 Godox receiver X1N-R for my old Nikon flashes ,so I can control every 3 units with the Godox R2 Pro?

    How do you get the R2 Pro to trigger the R1 receivers with AB’s? I have tried changing channels, ID, etc and can’t seem to get the R2 to trigger the R1’s. PLEASE HELP…. no info that I can find anywhere and the manual and Adorama have been NO HELP as well…. Anyone?

    In Him,

      They use different frequencies so they won’t work together. You need to replace your receiver with a Flashpoint R2 Bridge Receiver.

      However you can’t use either the R1 or the Flashpoint R2 Bridge Receiver to trigger Alien Bees. To do that you need an R2 TTL receiver and a sync cable.

    During a commercial dance session I had this trigger fail 10 percent of the time. I have no idea why but I won’t be using this trigger again.

      Mark, thanks so much for your updates….Which transmitter are you moving too?

    I have been stumped regarding my issue with the R2ProC. If anyone has experienced similar issues, please let me know the circumstances and IF you have been able to recreate the failures. Thanks
