I know there are some other threads in the internet about it, but I just want to mention it here too. I returned my first D7000 body because of a severe back focus problem that could not be corrected with the in camera AF-fine-tuning. The camera back focused with a new AF-S 50mm f/1.4G and also with a little older AF 85mm f/1.8D lens. The second body I got from a different store, has exactly the same back focus problem. It can't be corrected with the in camera AF-fine-tuning. For example, using a new AF 50mm f/1.4D with a setting of -20 there still was some back focusing. Very disappointing for such an expensive and new camera if you ask me. I sent the camera to a Nikon Service Point for repair and I am awaiting the results. I am just curious if there are other photo.net users that experienced the same problems with their D7000 camera.
