I've had a D7000 for almost 2 years. I always read that the D7000 was a bit more advanced than the D90 since the 7000 was newer etc. So I picked up a used D90 recently to have as a back-up and was comparing images, and it seems the 90 is sharper in all of the ISO settings that I used. Can anyone shed any light here? In my test I used all the same body settings, same lense, tripod mounted, same distance, everything the same.
