Adapting basics#
A lens can be adapted with simple tube spacers when its flange distance is longer than the camera's. With 50.70 mm, Tamron Adaptall lenses can in principle go on bodies with shorter flanges such as Contax N, KMZ Zenit DKL-mount, Leica R, Nikon F, Olympus OM, Yashica MA-mount. Bodies with this mount can take lenses from longer-flange systems such as Arri PL, Leica S, T-mount (T2), Mini T-mount, YS mount, Mamiya 6, Vivitar TX, Mamiya 7.
