So I have a d700, and I love it to death, but I can't help notice that whenever I put an AF-D lens in AF-C or AF-S, i can still turn the focus ring around, just with a bit more resistance. This doesn't seem to affect the actual autofocusing component at all, but with my old d80 I remember the lens being locked whenever I had the camera set to autofocus.
Is this a problem with my d700 body? Is there anything I should be wary of/ should I send it back to Nikon to be fixed while still under warrantee? Or is this normal behavior?
