I did that I few days ago. Focusing at 10 inch (centre of the view finder) - the 11 inch mark (further away from me) was sharp. I shot that test from appr. 2-3 meters distance witrh the FA 2.8/80-200mm.

Achieving AF within the sensor bounderies (not visible > to us) is all the system is going to do. An intersting, though mostly useless exercise is to take a picture of a ruler that is at an angle to the camera, and see where the focus is in relation to the chosen focus point. William Robb
