Re: My current method to determine AF-Fine Adjust values


I just gave this a try.  I very much like your general approach/concept.  However, what I did varied a little from the alternative approaches you mentioned.

What I did was do multiple focuses using live view with observation of where the distance scale of the focus ring most consistently stopped relative to a fixed mark on the lens barrel.  Then, I tried various fine focus adjustments using PD-AF until I was satisfied I found the right setting that most consistently set focus to that same point.  This method worked on all the lenses I typically carry around except for the 18-135 which doesn't have a focus ring that has distance settings (or moves when focusing for that matter).

Thanks for the tip!
