i have been using Zeiss lenses on the 5DSR and was frustrated by trying to use the green focus confirm light in the lower right corner...too hard to watch and not very sensitive. I then discovered that when you are using "auto focus point expansion", that the outer 4 (or 8) focus pts will blink out when in focus. The long focus throw of Zeiss lenses helps because that blinking out is very sensitive. When in focus these points go out but either direction past focus they reappear.
I noticed that on the 100 MP that focus was not perfect and then went to the afma settings to see if I could do that. You can actually record an adjustment for these lenses and also record their serial number. I almost always use my camera hand-held so this really has made a difference. I did what I guess is a "manual focus micro adjustment" for all 4 of my Zeiss lenses.
I think this should work for any manual focus lens if the camera reads exif data.
