My father has a 50mm 1.4 and some other lenses I wanted to use (35mm 2.8, etc). When i connect them to my D80 it writes "fEE" like an error, in the display and I can't take pics. When I put them on his D200 it works. According to websites, both should work so there is a setting somewhere in my camera that makes them uncompatible and I can't see which one is it. Any of you know?
