GODOX – X1-C – TTL Triggers for Canon – Now Available




Godox have released details on their soon to be available X1-C, TTL and HSS enabled 2.4GHz radio trigger system for Canon DSLRs.

The X1-C will be Godox’s first TTL enabled radio triggers available, and they will be released alongside the new TT685C Speedlite, with compatible radio transceiver built inside.

UPDATE – Nikon version X1-N, and Sony version X1-S are also now Available.


UPDATE - Godox have added a static Page Mode interface option, which stops the groups from moving around on the transmitters LCD screen. To Enter this mode hold down the CH Channel button for 5 seconds

There are more details on this Page Mode at the bottom of the post under the Custom Functions list.




The X1-C are separate transmitter and receiver units, with X1-C receivers being compatible with MK II style Canon compatible speedlites like the 580EX II and 600EX-RT etc.

As well as Canon ETTL compatible flashes like Godox’s own V860C.




As well as the traditional Canon A:B C ratio style interface, the X1-C provide a full GR Group style interface allowing up to 5 Groups to be individually set to either TTL, Manual, or Off.

So most importantly TTL and Manual Groups can be conveniently mixed together as needed.

PLEASE NOTE – GR Group mode requires camera models from 2012 onward.




The X1-C provide TTL, HSS (High Speed Sync) and most of the features comparable popular TTL triggers provide, even a HSS Pre-sync Timing Adjustment.

Godox have even considered small (though important) details like PC Sync Input and Output, something most radio triggers constantly miss.

UPDATE – Second Curtain Sync has been added to the X1-C transmitter from firmware version V09 onward. (Set Custom  Function 04 to 01 to engage).

  • AF Assist light (With an On/Off Switch)
  • Wireless Shutter Release
  • Micro USB Port for Firmware Upgrades
  • Transmitter PC Sync Port – Input & Output
  • Receiver 2.5mm Sync and Shutter Release Port – Output


The X1-C transmitter features a large clear LCD panel interface, and fast adjustment control wheel.

Godox have even provided a simple switch on the side of the transmitter allowing the Focus Assist Light to be switched on and off when needed.




X1-C receivers provide a simple Channel and Group selection interface.




The X1-C receivers 2.5mm Sync Port output can be used for wired and wireless shutter release, as well as firing studio strobes.





The X1-C will be Godox’s first TTL enabled radio triggers available, and they will be released alongside the new TT685C Speedlite, with compatible TTL radio transceiver built inside.The TT685C Speedlites provide both Radio Master and Slave modes.

V860C Speedlites can be fired and controlled off camera while being attached to X1 receivers. And even current Manual Godox Witstro (with X1-C receiver attached) can now be fired off camera with no extra transmitter units attached to the camera.

The Godox PB960 external high voltage battery packs providing a very fast recycle option with the TT685C Speedlites, on or off camera.










C.Fn-00 – Synchronization Delay Setting – [ 00 = OFF ] [ 1-100 US delay setting ]

C.Fn-01 – Single Contact Mode – [ – –  = OFF ] [ on = ON ] (stops transmitter going to sleep)

C.Fn-02 – Zoom Setting – [ – –  = No changes ] [ AU = Changes with lens ] [ 20, 24, 28, 35, 50, 70, 80, 105… ]

C.Fn-03 – PC Sync Socket – [ In = PC Sync connect with Camera ] [ ou = PC Sync connects with Flash ]

C.Fn-04 – Rear Curtain Sync – [ – –  = OFF ] [ 1 = ON ] (camera shutter must be between 30s – 1/30s)

C.Fn-05 – Enable 1/256 Power Level – [ 1/128 = OFF ] [ 1/128- = ON ]  (1/256 is displayed as 1/128-)

C.Fn-06 – Switch between 3 and 5 groups in GR Group Mode – [ 03 = 3 groups ] [ 05 = 5 groups ]

C.Fn-07 – Turn remote flash beep Off / On – [ – –  = OFF ] [ on = ON ]



A function to remotely turn the modelling light On and Off on strobes like the AD600B has also been added to the X1 transmitters.

Double pressing the Channel button will turn the modelling light ON or OFF.




After some persuasion, and the help or Adorama / Flashpoint, Godox have implemented a static Page Mode interface option, which stops the groups from moving around on the transmitters LCD screen.

To engage the Page Mode interface hold the Channel button for 5 seconds, or until the groups show again on the LCD screen (after the custom functions disappear).

A flashing Group letter now indicates the current Group selected.

– Single press the Group button – To scroll down groups.
– Double press the Group button – To scroll up groups.
– Turn the Dial – To adjust the Group setting.
– Press the Channel button – To lock in the setting (will also lock in automatically after 2 seconds)


(Unfortunately this is still not quite as we suggested, which would be using the dial to quickly select groups. Though at least the groups are not constantly scrolling around on the LCD screen now).

Godox have also implemented Custom Function C.Fn-06, which allows the display of just 3 groups when you’re currently not using all 5.

This makes it faster to scroll through (by continually pressing the Group button) just 3 groups all displayed on the one page, to select the group you’re after.





The Godox X1-C TTL triggers for Canon are available now from around $80 a set of Tx & Rx –

    Hey guys,

    I recently purchased a Godox c1c transmitter and receiver. It has the most recent firmware so i assume the ones i got is the currnt production. No sliding hot shoe. However i have an issue with its hss (high-speed sync). This is the combination:
    I have an outdated 450d (yeah, but still shoots fine)
    I use it with triopo tr-982ii (hss,ettl etc)
    The default firmware of the reciever was ver16. Due to this, i wasnt able to use the M mode. What i did to solve the problem was update it with ver17 and it fires the M mode. Also, worth noting that gr mode doesnt work with 450d.
    Now heres my problem:
    I cant make HSS work even though the TR-982ii has built in hss. I’ve tried setting the flash on hss but no luck, goes back to non-hss.
    Now my question is this, is it a flash issue or x1 issue that doesnt allow me to use hss?

  5. Richard 6 months ago

    Hey, can you confirm whether or not the X1T-C transmitter can double as a receiver? Can I use one X1-C to trigger another one without using the separate X1-R receiver?


  6. Jules 6 months ago


    I got a problem if anyone can help please.

    Camera is 5D3 (with X1T) and ex430ii (with X1R). The flash itself will only operate in TTL mode regardless of any setting on the X1T. I can’t get the ex430ii to stay in manual mode. Both are on firmware v15. Any ideas what’s wrong??

    It all works fine with my pair of TT600 and in TTL on the Canon flash. But cannot get the Canon flash to operate in manual mode. :(

      Hi Bryan,

      Yes, if you mean the V850II.

      The original V850 would require clip on 2.4GHz XTR16s receiver to be compatible with the X1 transmitter.

    i have an issue with my canon flash ex 430II and godox tt600 , when i place on the hotshoe the canon flash in X1c doesn’t work pass thru am i doing something wrong ?
    example: i set the TT600 and the X1 same group & channel when i change value to TT600 Thru the X1 the canon flash in the hot shoe it turns from TTL to manual…

    if anyone can help.

    Did anybody successfully fire a flash with the Godox X1T-C and the Canon eos M3? My Godox TT685 & the X1R ignores manual and TTL mode.

    • Jesse Patterson 4 months ago

      Not me. The M3 has always had issues with third party flashes and triggers. I hope Godox comes out with a firmware update for both the M3 & M5 since I also use speedlites with those cameras.

  12. Sebastian Corzo Alvarez 4 months ago

    Hi, i have the old FT 16s receiver for my v850 and v860C if i buy only the X1 transmitter (or transceiver whatever you call it) i could control my flashes like the ft16 transmitter? for the HSS for me doesnt matter because i have CELLS II for HSS. I only want that X1 godox for the AF Light dont need TTL or HSS i just want control the flashes (power controls on – off and these things) Hope you can solve my doubt

    Can two X1 transmitters be used simultaneously to fire one AD600?

      There obviously needs to be enough time to recharge but I have run a workshop with 3 or 4 using simultaneously which was a mix of Canon and Nikon

    Has a firmware update fixed the issue of the X1 not being able to turn off groups with the XTR-16 receivers? I can’t move to Godox until that is fixed.

  15. Andy 3 months ago

    I have question on C.Fn01 of Transmitter X1C-T
    C.Fn-01 – Single Contact Mode – [ – – = OFF ] [ on = ON ] (stops transmitter going to sleep)

    I am sure I understand how this is used. Here is my case
    I have Panasonic GX85 which obviously not using TTL in this case. So, When I set custom function Fn01 to “On”, I can fire the flash with X1C-T on top on Panasonic GX85. However, when I set C.Fn01 to “–” mean Off, I am still able to fire the flash no problem.

    So, I have no idea what the point of this function is. Of course, I’m happy that I can use X1C-T with both Canon and Panasonic cameras. I Just want to understand how it works ( I have latest firmware installed in X1C-T)


    • Don 3 months ago

      The single contact will always fire the flash, but the other contacts are off (used to transmit and receive the Canon camera data).

      • Wolf Dieter 3 months ago

        - The single contact will always fire the flash, …
        No, it does not. My EOS M3 does not fire a flash.
        – … but the other contacts are off (used to transmit and receive the Canon camera data).
        No, they are not. Otherwise my camera would not display the flash menue (EOS 7D).

        I see no difference in in C.Fn-01 (Firmware V19). Perhaps mine is defect?

      Hi Andy,

      Yes, I don’t know why the C.Fn-01 does not actually disable the TTL contacts, as you would expect it should.

      As noted, all that function appears to be currently useful for is stopping the transmitter from going to sleep.

      I was going to bring this up in regards to developing the new transmitter.

      Hi olyshooter,

      Yes Godox do have plans to provide Olympus/Panasonic and Fuji TTL support this year.

      Though I wouldn’t take that as a guarantee it will definitly happen this year.

      Hi nixland,

      I really don’t know if Godox have any intention to implement pre-2012 Group mode or not. I’ve never heard them say this is something they intend to do.

      I don’t know how difficult it is to implement with their system either, so its not something you can really pressure them to do.

    Does anyone here have a problem with Godox trigger in TTL mode?

    Aside from being super unintuitive, mine always missed TTL by … large margin. I have tried couple 600RT`s and then same with YN622 triggers and they are all spot on. Then i tested it with godox X1T and X1R with same 600RT flashes and image was overblown. Even putting -3EV wasnt helping much.

    Anyone had similar experiences?

    Hi all

    I am trying to set up lighting session, I use Godox AD600, Godox V860 II, I want to trigger both speed light and the strobe, I miserably failed to do it.

    Can someone please let me know how can I use both flash and strobe at the same time by triggering them with X1N triger

    • Author
      Flash Havoc 1 month ago

      Hi Walid,

      That shouldn’t really be a problem, as long as you have the flashes and transmitter set to the same channel and groups as needed.

      Where you able to get either of the flashes alone working with the transmitter to start with?

    Are the godox x1c transmitter and receiver compatible with canon 5D Mark IV? I’m using a Canon speedlites 600 EX-RT, 580 EXII.

    • Author
      Flash Havoc 3 weeks ago

      Hi Julia,

      Yes the X1 triggers are compatible with the 5D Mark IV. You need at least V18 firmware in the X1T-C transmitter for the AF assist light to work though.

      I’m not that familiar in general if the X1 receivers have any quirks at this stage. Maybe some regular users can help chime in on that. A lot of people just go straight for the TT685 flashes etc now for the convenience rather than buying separate receivers.

      • Julia 3 weeks ago

        Thank you. One more question, I have changed the unit (X1CT) to show just 3 groups, is it possible to set it so the A channel remains in the selected position even after powering the unit off? In otherwords, where I don’t have to always scroll to the A channel to get it to the middle working selection? Or, have the unit always be set A B C without bouncing around? Thank you!

        • Author
          Flash Havoc 3 weeks ago

          Yes you can use the “Page Mode” interface option which stops the groups from scrolling. It still takes some getting used to though –

          “To engage the Page Mode interface hold the Channel button for 5 seconds, or until the groups show again on the LCD screen (after the custom functions disappear).

          A flashing Group letter now indicates the current Group selected.

          – Single press the Group button – To scroll down groups.
          – Double press the Group button – To scroll up groups.
          – Turn the Dial – To adjust the Group setting.
          – Press the Channel button – To lock in the setting (will also lock in automatically after 2 seconds)”

          Its still not ideal, though Godox decided to work on a new transmitter rather than refining the X1 interface further.

          • Julia 3 weeks ago

            Thank you for those directions. I will give it a go tomorrow. Are they coming out with a new triggers for Canon soon? I just bought these, do you think they’ll be significantly different and will they be compatible with previous x1ct and r’s.

            Thanks a bunch!

              No worries, the new X2 transmitter will likely be available late in the year. They will have a large LCD screen and a lot more user friendly interface.

              They should be compatible with the current flashes and receivers.

    I have the x1 for canon.

    when use ti with canon 580 ex ii , i noticed that only fire the flash , when the head of the unit is in “normal” position

    anyone have problem with the x1n-r triggering studio strobes like bowens??

  25. Jeroen 2 days ago

    Hi, I’ve just bought the AD360(original, not v2), a X1 and XTR-16. Everything works fine up till 1/250. Hss is always out of sync. I have hss enabled on the flash and my 70D also shows the hss icon.

    I’ve researched a lot before I bought and this setup should work with hss, saw a working example on YouTube(with a A7RII though). This makes me think I’m missing a setting on my 70D. Any help?

    • Author
      Flash Havoc 15 hours ago

      Hi Jeroen,

      I just gave it a run on the 6D, 7D, and 5D IV, and they are all working fine with HSS.

      Do you have the X1T transmitter on the latest firmware (V19)?.

      Also are you sure the flash is firing in HSS pulses? You should be able to hear the difference in the flash pop sound when you turn HSS on and off and test fire the flash.

      • mmmfotografie 14 hours ago

        On the 360 you have to switch it manually to HSS and it will stay in that mode till you switch it off again. Also the XT16 can not communicate back if it is HSS mode so any indication is generated by the transmitter.

      • Jeroen 13 hours ago

        Thnx for your reply! I’ve updated the X1T to v19, but no improvement. Everything is fine up to 1/250, but any higher and the flash is not syncing with the camera. I have the AD360 in HSS mode. I think it’s in HSS mode, when the flash fires it’s a softer “pop” sound.

        • Author
          Flash Havoc 6 hours ago

          Ok thanks, it sounds like you may have a faulty receiver unit then unfortunately. I think this was an issue with the very early XTR-16, though that was quite some time ago now.

          I’m not sure what else it could be otherwise. I don’t think anyone has mentioned issues with the 70D in particular.
