"RE: FoCal or FocusTune?"

Richard, I saw all of your posts and read online about AF fine tune for zoom lenses. Yes, unfortunately, it is a compromise. I have hard time understanding how one can select a single focal length for a zoom based on their uses, but at least testing you can see how the lens behaves and whether it is within reasonable margins. Also you can adjust it to give you better results that it provides now, which also would be a good thing. Not ideal, but better than with no adjustments in case when a lens needs a lot of AF fine tuning.

Btw, what kind of lighting did you use when testing?
