Just received the D7000. Right know just getting familiar with the camera and just experimenting with random useless shots. The lenses I am using are older AF lenses (circa late 80s early 90s). I tried using the camera with a 28-85 lens. When I select the aperture priority mode I get an Fee error message if I try to select an aperture on the lens. It seems I have to lock the aperture ring and use the dials on the camera instead So am I right to assume the lens aperture ring on the lenses (at least my generation of lenses) is useless with this camera.
