Issues with a used lens
Just received a used 300 f2.8 af-s in the mail and I'm having some trouble. I have locked the aperture at f22 on the lens but it is saying f6 on 3 cameras and won't budge. It also won't af at all. If I manually rotate the aperture ring it goes down at even increments until I hit f0 on the camera (f2.8 on the lens). I tried cleaning the contact points with no success.
I have an old 80-200 one ring that works fine on the d300 and d700.
I'm hoping I'm just overlooking something in my excitement. Anything that comes to mind would be appreciated.
