Adapting basics#
A lens can be adapted with simple tube spacers when its flange distance is longer than the camera's. With 64.00 mm, Contax 645 lenses can in principle go on bodies with shorter flanges such as Ricoh 126C-Flex, Hasselblad H, Mamiya 7, Vivitar TX, Mamiya 6, T-mount (T2). Bodies with this mount can take lenses from longer-flange systems such as Zenza Bronica ETR, Pentax 645, Rollei 6×6 (SL66/SLX), Pentacon Six, Hasselblad V, Kowa Six/Super 66, Kiev 88 / Salyut, Hasselblad 1000F & 1600F.
