I just got a Nikkor 50/1.8 AF non-D lens. It works properly on my F100, N8008S (manual aperture), D7000 and D700. On my N80, the FEE message shows up and it can't be used in any mode. What is strange is my AFD and (one G) lenses work normally on the N80. I have double checked that the aperture ring is locked on 22, cleaned the body and lens contacts. From what I have tried, it seems that both the body and lens are OK. What have I missed? Any help is appreciated.
