When I mount at f5.6 the indexing tab that tells the camera the max aperture of the lens only goes to like 3.5 after I set it. It will go to 2.8 if I open the lens to 2.8 but if I'm not shooting wide open, it will stay at 3.5
I've tried mounting at f22 and nothing.
EDIT If I slam the aperture into 2.8 it stays at 2.8, I think it might be a mount issue. hold on a min, I always fix shit minutes after I post on APUG
