I've had my D7000 for just over a year now and been extremely happy with it. But over the last couple of photo ops I became aware of a focusing issue. I immediately began a search of the web and realized other people were having questions about the focusing capabilities of their D7000s as well. I ran some tests and reviewed my images to find evidence for or against my suspicions. I also ran some rudimentary tests using different lenses and even flash and high shutter speeds. sure enough, my camera seems to have begun back focussing by at least 10% regardless of lens used. The issue is definitely a new development. My older pictures are very sharp. Now here, I'm going to hopefully add some helpful info. First of all, the only thing I have done recently with the camera that could possibly have caused some software corruption is to set up U1 and U2. Perhaps that action somehow introduced corruption into the software somehow. The rest of you guys who are interested in this subject please consider this possibility and see if I may have something here. next, and this is a big one. I went to metadata exif in CS Bridge and looked at subject distance. Ureka!!!!! The figures are all over the place from 0.0 to billions of meters! Has anyone noticed this before? How could all of you experts have missed this!
