I'm getting a D80 this weekend and I'm wondering if my grandfather's old Nikon lenses will still work on them. I think he bought them around 1981, but I can't find much online telling me one way or the other. Here's what I've got: Nikon Series E 28mm f/2.8 Nikon Nikkor 105mm f/2.5 Soligor 75mm-260mm f/4.5 (to fit Nikon AI) Plus the M500T-ZOOM flash - not sure if that would work with the D80 either. Anyone have any clue? A site that might be able to help me out? Googling hasn't helped me much. Also, will the picture quality be greatly affected? Thanks.
