Hello. I have recently encountered issues with the RF 100-500 eye auto focus. The last two outings, I have tried to use the eye auto focus and the 100-500 lens does not lock on the eye. I can then switch to the RF 800 f/11 and the eye auto focus works without issue. The first time it happened I checked to see if I needed to update the firmware on the lens/camera. There was a firmware update for the R5 so I applied it and hoped that would work. I went out again this past weekend and had the same issues with eye autofocus not working. Any suggestions on what could be happening?
Thanks,
Eric

Firstly for the EOS R5 eye autofocus only works when the camera AF method is set to face + tracking, or you have a back button configured to eye detection AF and use that.
With the RF 800mm F11 lens you only see a central frame where AF is working. For the RF 100-500mm the whole frame is used to detect the subject.
