Film Perforation Holes Seen in Photos
Early Leica Screwmount Cameras have this problem from the film slightly falling down in camera (gravity) exposing the top film perforations as seen in photos. About 1/2 way through the lllf production Leitz added a film tab -on the inside of their baseplate to keep the film from falling down. Cameras that can take the new style baseplate have a keyway milled out to accept the baseplate tab. I can mill out a keyway in the earlier Leica S.M. camera so the new style baseplate (only lllc & lllf models) can be used. Since the nrgatives are up-side-down & backwards, the film perforation error is seen on the bottom of the photos as seen in one of Robert Capa's photo.
