EOS R3 autofocus issues after upgrade to firmware 1.8

[czbrat3962]

I updated the my Canon R3 to 1.8 firmware because I had an issue with my camera freezing during a football game.  What a mistake that was.  Now my camera won’t lock on focus.  I have all of my settings set to where I had it before.  Now when I try to lock on a player it’s floating all over the place. Before I was locking a player, then eye detection would take over for nearly two years. Worked flawlessly. Now my camera is a POS. I know a few other photographers having similar issues with the update.  I have did a factory reset and reinstalled the update same issues. Last night during the football game I disabled everything and shot the old fashioned way.  Now going to try and downgrade my update. So frustrated.

I ended sending the camera to Canon.  The camera needed the focus system to be recalibrated.  Seems to be working now.

May I ask you to tell me in more detail what exactly is meant by recalibration? What exactly did they tell you in your particular case? Because when I came across a problem, I was surprised by it.

When I focused on a person's eyes or head, the objects below or to the side were in perfect focus, something like front or back focus on SLR cameras, but not quite like that. But it seems that firmware 1.8.0 solved this problem, at least specifically for me. But there's less filming now, so it's hard to say for sure.
