Re: Have any of you experienced the "Error 20" problem?

After a while the fault recurred . Back to Canon it went and they changed the mirror box assembly .

The fault did nor recur but ever since the repair my photos on all Canon lenses were not as sharp as before. The non Canon ones were find.

OK. I just checked focus on my 5D MK IV. Everything works fine with my Canon lens and also with my Zeiss Otus. Perfect focus. I'm relieved.
