The external Flash is not showing up in the configuration Menu when using Pixel TF-321 hot shoe. Is this the wrong adapter for that camera, as there is no X connection? I want to trigger a studio flash via sync connection. Can you recommend me a working hot shoe? Thanks!

Unfortunately, your canon EOS 4000D is a very stripped down entry level camera. Looking at your photo of the hotshoe, I now realize that Canon has removed or eliminated the center hotshoe contact. This is the contact you need to make the sync connection with your Pixel TF-321.

The 4000D will only work with Canon brand ETTL flash units.

There is no way that I can think of to make your camera sync with an external studio flash.

Any other Canon camera would have had this contact. I find this very troubling and I can't really see how this can be seen as a cost saving measure.

  • Thanks, I added my studio light. It doesn't work with the TF-321. Am I doing something wrong? – Sto Dec 20 '18 at 19:45
  • I just measured all of the connections. On the TF-321 the inner of the PC connection is not connected to any of the pins on the top or bottom. Could it be that the adapter is just broken? – Sto Dec 20 '18 at 21:35
  • @Sto I have just edited my original answer. Canon has removed the center contact from the 4000D hotshoe and any normal hotshoe adapter will not be able to sync with the camera. – Mike Sowsun Dec 20 '18 at 21:37
  • I don't mind soldering anything anywhere, but I need that triggered :/ Looking really forward to a solution. This is supposed to be locked in a photo booth. Thanks! – Sto Dec 20 '18 at 21:55

    @Sto The simplest solution in this case is to go with a camera that has a hot shoe the meets the ISO standard. – Michael C Dec 21 '18 at 2:47

Apparently Canon has removed the ability to manually trigger a non E-TTL flash with the 4000D by removing the center pin of the camera's hot shoe.¹

This is supposed to be locked in a photo booth.

If you are bound and determined to use the EOS 4000D, with it's non-ISO compliant crippled hot shoe (SHAME, SHAME, SHAME, on you, Canon!), then you might try reflecting the output from the camera's built-in flash to the optical sensor in the strobe with the strobe set to 'Photosensor' triggering mode. Set the camera's built-in flash to manual flash power. Turn off red-eye reduction plus anything else that causes a 'pre-flash'. Since the camera is mounted inside your photo booth, it should be fairly easy to block the camera's flash from directly illuminating the posing area while bouncing the light from it inside the 'behind the wall' area to trigger the strobe.

¹ Which, in this case, should probably be called the 'somewhat lukewarm shoe'.

  • Thanks. That seems like a good solution, I will tape a light sensor to the built in flash, that goes to a sync cable. I hope I can adjust the trigger timing too, would be perfect 👌🏻 – Sto Dec 21 '18 at 9:09

There is a solution - Godox XPRO-C. 70 bucks and I'm able to use the sync! Works with 2000D and 4000D!

  • Glad you found something that works for you, even if your solution is not exactly what the question, as written, asked for. – Michael C Jan 2 at 22:33
  • Well it's a working hot shoe "adapter" that runs without the middle / X contact. Not even Canon is providing anything like this. I even opened a ticket with them looking for a product – Sto Jan 2 at 22:47
  • I guess so, if you consider a 'hot shoe' and a 'hot shoe adapter' to be the same thing. – Michael C Jan 3 at 3:30
