Exactly. This is what I found with my FA85 1.4 and my *istD. It looked in focus in the viewfinder, but the actual point of focus was just a little behind. If I used autofocus however, it was spot on. I had no problems with other lenses that I noticed, but then again, I never did extensive testing on the others. I had no problems with focus with the 85 and my film cameras. This is why I wonder if digital cameras have some type of intrinsic issue with differences in viewfinder/CCD light paths? They shouldn't, but so many people have reported back/front focus issues that it makes you wonder. Of course, the ability to instantly magnify images to 100% on the screen and beyond may be part of the problem.
