Adapting basics#
A lens can be adapted with simple tube spacers when its flange distance is longer than the camera's. With 38.67 mm, Four Thirds lenses can in principle go on bodies with shorter flanges such as Minolta V-mount, Nikon S / Contax RF, Contax RF-mount, Hasselblad XPan, Contax G, Olympus PEN F. Bodies with this mount can take lenses from longer-flange systems such as Konica AR, Konica F-mount, Canon FD, Canon FL, Start, Minolta SR / MC / MD, Fujica X, Petri Bayonet.
