Canon 50/1.8 won't mount centrally on Canon P>
Hi, new member here. New to me Canon P & Canon 50/1.8 in separate purchases from Japan. Lens is not Centered when mounted but about 1 cm to the left of the camera's center line. Does the same on my Nicca 3-F but strangely, mounts almost dead center on my Fed 5B. My first test film with it on the P shows it is indeed remarkably sharp. However I am disconcerted by the fact that the camera & lens, both by Canon, do not collaborate! Also irritating to (by habit) center the chosen aperture and over expose by two stops. Have I bought a goose? Can someone explain what causes this. Got no input over at Classic Manual Cameras (PhotoNet). Many thanks for your advices.
