About the Pentax 6×7#

Bayonet of the Pentax 67 'super-sized 35 mm SLR'.

Adapting basics#

A lens can be adapted with simple tube spacers when its flange distance is longer than the camera's. With 84.95 mm, Pentax 6×7 lenses can in principle go on bodies with shorter flanges such as Kiev 88 / Salyut, Hasselblad 1000F & 1600F, Kowa Six/Super 66, Hasselblad V, Pentacon Six, Rollei 6×6 (SL66/SLX). Bodies with this mount can take lenses from longer-flange systems such as Zenza Bronica S2A, Rollei SL66, Mamiya RZ, Mamiya RB.
