Petri Bayonet mount

A lens can be adapted with simple tube spacers when its flange distance is longer than the camera's. With 43.50 mm, Petri Bayonet 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 Exakta, Pentax K, M42 screw mount, M37×1, Contax/Yashica (C/Y), Mamiya Z, Deckel (DKL), Braun Paxette Reflex DKL-mount.
