They allow the use of P6 lenses on Mamiya 645, Pentax 645 and Contax 645 medium format cameras, Canon EF, Canon FD, Nikon F, Minolta AF, Minolta MD, Contax/Yashica, Pentax K, M42, and Leica R 35 mm cameras, as well as Lumix and Olympus micro 4/3 (m4/3), 4/3 system. It has an "internal collar" that is turned by a tab accessible from the front of the camera. However it returns to the breach-lock origins of the mount. Like the earlier Kiev 88 modifications, the lens is recessed in the front of the camera body. The Kiev 88СМ is a later version of the Kiev 88 manufactured with a P6 mount from the factory. Ī consequence of these early modifications is that the lens mount became twist-lock instead of breach-lock the lens is inserted and turned. This causes physical clearance issues with some lenses, particularly the Exakta 66 lenses with a cam and possibly a pin for coupling the lens to a TTL prism. A major issue is the fact that the Kiev 88 has a greater flange focal distance than the Pentacon Six, requiring the lens to be recessed into the front of the modified Kiev 88. Thus various third parties worked to machine a P6-compatible lens mount into the Kiev 88. However, there was interest in using Pentacon Six mount lenses from Carl Zeiss Jena and others on this camera (nicknamed the Hasselbladski). Like the Hasselblad, it has a threaded lens mount and Kiev-Arsenal manufactured its lens range in both the Pentacon Six mount (for the Kiev 60) and the Kiev 88 screw mount. The Kiev 88 is essentially a clone of the first Hasselblad - the 1600F/1000F. And for lenses with a maximum aperture other than f/2.8, a separate pin projects from the lens to the prism to tell it the maximum aperture.
It does this by projecting slightly over the front of the camera, allowing a rotating cam on the specially designed Schneider lenses to tell it what aperture setting was selected. The Exakta 66 added a TTL metered prism coupled to the shutter speed dial on the camera body and the aperture ring on the lens.
This variant is seen on the Praktisix, Pentacon Six, Kiev 6C and Kiev 60. The lens is inserted into the front of the camera and is held in place by a rotating collar. The flange focal distance of mount is 74.1 mm.
A pin holds the diaphragm open for fully open metering and focusing this pin is released before the shutter is opened. It has three short tabs on the lens they are identical and correct orientation is assured by the placement of a post in front of the "top" tab.
