Recently I have noticed that my EOS R is having trouble focusing.
I am using back button focus with AI servo but this also happens with the AF and metering bound to the shutter button.
Basically, if I have the camera to my eye and select my AF point then hit the focus button it regularly can't focus on an object. If I look at the live view and use the focus button it is the same problem, but if I tap the screen to focus, the camera focuses just fine.
I have tried finding more contrasting areas to focus, different AF modes, larger AF points and with and without back button focus.
I have also tried 3 different lenses and it seems to be the same in each.
Here is a video showing the problem:
in the video I am in manual mode, using back button single point AF with the RF 24-105
Yes, that is certainly the case depending on the setting to fire w/o focus being achieved. But that still would suggest, again, that the problem is with the RC-6 trigger and the difference in timing with just pressing the shutter button. And so also suggest a problem with the R-series cameras, since this has not been a problem with any pre-R series Canon camera I've ever used.
