I recently bought a Yongnuo YN565EXII flash to be used with my Canon EOS550D/T2i camera. I am really happy with all the tests I have done with this flash since I got it two weeks ago, except for one weird issue that I am having.
With the flash connected on the hot shoe and working perfectly well, it won't fire when I use a remote shutter release (R-6) also from Yongnuo. I have tried with the camera's built-in flash, and it fires the flash, but not the external flash. When I press the remote shutter, it releases the shutter, but doesn't fire the flash. Then I change to single shot, I press the camera shutter and the flash fires. It also fires with the self-timer, if I shoot from the camera.
Has anybody experienced the same issue and been able to fix it?
Any help will be appreciated!!
Thanks in advance,
