i can't speak for nikons themselves, but I do know there are issues with the lenses and the field of view. Like sometimes, a 50mm lens will be 50mm on a film camera, but due to the aspect ratio of the digital camera, it becomes a 70mm lens, and stuff like that. Not all Nikons will accept all nikkor lenses. My N2000 is compatible with zoom nikkor, pc-nikkor, reflex nikkor, and AI-Nikkor lenses, but there ain't a chance in hell n auto focus nikkor lens will work on it. Then again, I only started shooting again after a 2 year hiatus in the past month, really, so Alpha's the man to ask here, he uses digital and film Nikon SLRs.
