I have a D3100, and my roommate sold me his AF Nikkor 50mm. It was working fine...However, now when I try to use it my display says "lock lens aperture ring at minimum aperture...", which I have done but I am still getting a notification on my display...is this an easy troubleshoot or is something seriously wrong with the lens?...If you can tell, this all a bit new to me...help?
