I have been putting my new 6D through it's paces today. Testing it.
I will keep this brief, and simple. I have a eg-s screen in my 6D and have adjusted that setting in CN
Edited: Tested on both my 24L and my 50 1.4 at f 1.4 It is not a lens issue.
Then set on a tripod near minimum focal distance, AV mode, AF single shot, BBF, center point focus, the image in my viewfinder appears OOF, when I take the picture it is perfect on my LCD.
When I turn off AF and manual focus it, the image is tack sharp in my viewfinder, but the final image is OOF on my LCD.
It is not an AF issue, it is an issue comparing my viewfinder image with my final image taken.
I have already tried adjusting the tiny dial on the right of the viewfinder with no luck. It is not an AF issue and therefore, not a micro adjust issue.
The issue is what looks OOF on my eg-s screen is perfect and what look perfect on my eg-s viewfinder is actually OOF
