Hello, I am asking this for a friend who uses a Mamiya 7 and is interested in buying fu nky old uncoated lenses to create a pictorial or antiquated effect. I am not fam iliar with that camera so I couldn't help her, but figured someone here would kn ow. The main question is whether the old lenses need to have a shutter, or shoul d the shutter be removed, and what sort of adpater might be necessary to mount t he lens on the camera. Does anyone have any insight into this?

Thanks, Sandy
