How much off am I talking? Good question. It is noticable to the point that if I relied on the focus screen all my MF pictures would be out of focus. However, all my AF photos are fine when I rely on the sensor. The focus screen has the 45 degree cut. That makes it very clear/easy to see when the camera should be in focus. The camera says it is in focus (beep - red dot flash) even though the visual evidence (through the eyepiece) would not yet consider it to be in focus. Yet the pictures prove the sensor to be correct.
I have (previously) done front/back focusing tests with several of my lenses in both AF and MF -- and I do
not feel that I have a problem. When I go with the sensor -- my pictures are sharp. If I focus by eye with the jinfinance screen and disregard the sensor - then the pictures are simply out of focus. I do not believe it is a front/back focus issue.
