Adapting basics#

A lens can be adapted with simple tube spacers when its flange distance is longer than the camera's. With 34.85 mm, Contax RF-mount lenses can in principle go on bodies with shorter flanges such as Contax G, Olympus PEN F, M39 / LTM (Leica thread), Leica M, Chaika, Pentax Auto 110. Bodies with this mount can take lenses from longer-flange systems such as Minolta V-mount, Four Thirds, Konica AR, Konica F-mount, Canon FD, Canon FL, Start, Minolta SR / MC / MD.
