Which Pentacon Six lenses will NOT go on a Kiev 88CM?
The most well known troublemaker is the fat barreled CZJ Sonnar 180mm lens. The barrel of this lens is too thick to seat into the lens locking ring of the unmodified 88CM (this is not an issue with the Kiev 60). Fortunately, if you already have a Kiev 88CM and a Sonnar 180mm you’d love to mount on it, Colin’s Kiev page provides the information you need on how to modify the Kiev 88CM lens locking ring to accept the Sonnar 180mm lens. The depth of field preview lever on the 50mm Flektogon and 80mm Biometar reportedly prevent proper mounting on some Kiev 88CM’s. Again, tolerances vary. However, if you are not afraid of modifying your lenses, the depth of field preview lever can be easily removed from the lens with only partial disassembly. The Carl Zeiss Jena lenses are also known to push a bit too strongly on the aperture actuator arm inside of the Kiev 88CM body. This arm is in turn connected to the mirror and the pressure can shift the mirror out of proper alignment making accurate foc
