"AF fine tuning"


Rambouillet, FR
          

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?

No, that's not possible

I believe the newer Sigma lenses (those compatible with the USB dock) allow you to set specific focus adjustments for different focal lengths.

They do, and it works like a charm. But one option for the Nikon user is to send it in, because the factory can probably adjust focus at various focal lengths.

I say this because Sigma can do it with the non-USB dock lenses.

I would send in the lens with a clear description of the behavior.

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.

Focus errors at the long end are much more noticeable because of the reduced DOF so it's better to fine tune there than at the wide end of a zoom.
