This is very preliminary, and I plan to do more testing. I received my D7000 two days ago and have been very happy with the results except for an occasional not-so-sharp image. I believe I narrowed it down to VR operation, on two VR lenses, my 16-85VR and 55-200VR.

I perceive a vertical "jump" at slower (not extremely slow) shutter speeds, which is not there if I turn VR off. The four images I have attached were all shot at F11 and ISO 100, 1/100 ss on the 16-85VR and 1/125 on the 55-200VR. I have shot many more images, both with VR on and off, with consistent results. Again, fine detail in the image (look at the small bright sunlight reflections) is smeared primarily in the vertical dimension.

I still have my D300, and it does not exhibit this problem. At first I thought it might be lens whip, but it does not occur with VR off. Has anybody else observed a similar problem? Of course I may have a defective unit, so the next step is probably contacting Nikon.

Added by edit - In vertical sequence, the images are 100% crops

16-85VR @ 85mm VR on
16-85VR @ 85mm VR off
55-200VR @ 200mm VR on
55-200VR @ 200mm VR off
