This sounds like an encoding or programming error of the exit pupil distance supplied by the lens EEPROM @ 200mm to the camera over the RF mount. On-sensor PDAF mechanisms need the precise exit-pupil distance to correctly calculate the phase differentials seen at the on-sensor phase pixel pairs.
I thought this would only be necessary to calculate the amount of movement needed to bring the phase differential to 0. I can tell you that the camera continues to believe that it is in sharp focus. If you press the shutter button again, or have it in AF Servo, it still stays out of focus.
I am curious if anybody here has a 180mm macro and an EOS R. I’m really wondering whether this is a telephoto close focusing limitation off DPAF, but I do not have access to one of these lenses. I would like to eliminate this as a possibility.
