Rollei QBM mount

Rolleiflex SL35 bayonet.

A lens can be adapted with simple tube spacers when its flange distance is longer than the camera's. With 44.50 mm, Rollei QBM lenses can in principle go on bodies with shorter flanges such as Canon FD, Canon FL, Start, Konica AR, Konica F-mount, Four Thirds. Bodies with this mount can take lenses from longer-flange systems such as Deckel (DKL), Braun Paxette Reflex DKL-mount, Voigtländer Vitessa T DKL-mount, Yashica MA-mount, Olympus OM, Nikon F, Leica R, KMZ Zenit DKL-mount.
