Since we talk a lot about lens sharpness, let's talk about that for a minutes. One of the features of the D7000 over the D90, and the lesser cameras is the Focus Fine Tune feature. One of the past problems of the D7000 has been many reports of back focus issues... some that exceed the range of the Focus Fine Tune adjustment...I recently bought the SpyderLensCal target to methodically calibrate and adjust all my lenses... I was moderately shocked at the amount of adjustment I had to apply to my lenses... I'm getting old and blind, so rely more on the auto focus feature of my cameras than I did in the past. I have a couple of Tokina lenses. The D7000 does not recognize those lenses in its Focus Fine Tune feature. It apparently only sees chipped Nikkor lenses... My Tokina lenses calibrate with a bit of back focus, but unfortunately I'll have too turn off the auto focus and manually focus them because there's no adjustment using the Focus Fine Tune feature with non-Nikon lenses...If you rely on auto focus, then you may give a higher priority to the Nikon lenses... especially with the D7000</blockquote>
