Canon r5 back focusing - micro AF adjustment missing???

haring · Apr 23, 2021

I have a brand new Canon R5. I noticed a horrible back focusing with my 35mm 1.4 Mark I. lens.
I have tried to micro-adjust focusing but apparently there is no option for micro-adjust AF in the menu... ?????
Anybody facing the same problem????
Thanks!

Since the sensor is doing the focusing, there's no AF point to adjust, so in theory, micro-adjust shouldn't be needed (or indeed useful). Doing a quick search, this thread describes how someone else had a front-focusing issue which turned out to be a mis-configured AF. https://www.fredmiranda.com/forum/topic/1680298

Also might be worth contacting Canon and finding out if there's a firmware update for the lens (or the camera).

Strange is that the camera does it with this lens only.
