I have a 17-55mm, which I like very much. I have found however that either there is a lot of focus shifting going on, or maybe it's just hard for the auto-focus to nail critical focus with this lens, I don't know.
So my question is: is it possible to set two different AF fine tuning settings for the same lens on the D7000? For instance, one for the wide end and one for the long end?
In my own personal experince with the 17-55 while experimenting with focus fine tuning I found that at the wide end this lens while fairly accurate, there was a significant difference in the precision when compared to the long end.
In general I found the accuracy to be acceptable and not in need of fine tuning on my D7000.
