The Konica SF (コニカSF) is a 4.5×6 SLR camera made as a prototype by Konishiroku in 1967.[1] It has exchangeable film backs for 15 frames on 120 or 30 frames on 220 film, a metal focal-plane shutter by Copal (1–1000, B),[2] and through-the-lens metering for shutter-priority automatic exposure. The design allows for interchangeable lenses and finders, and the lens mount is compatible with Hasselblad. The lenses made for the Hasselblad can be mounted on the Konica SF but can be used in manual exposure mode only. The dedicated SF lenses have an additional pin for auto-exposure operation, and they cannot be mounted on the Hasselblad.[3] The film advance knob is interchangeable too and can be replaced by an advance crank; this would have allowed the future development of a motor-drive.[4]

Two prototypes were made,[5] and one of them has been photographed and exhibited with a pentaprism finder and an 80mm f/2.8 Hexanon standard lens; it was notably displayed at the JCII exhibition about Konica and Minolta in 2005. Prototypes of a wide-angle 50mm f/3.5 and a tele 135mm f/3.5 were made, and other lenses were planned but never made: 35/4, 180/4.5, 250/5.6 and 500/8.[6]

The Konica SF never went into full production, partly because of the death of the main designer.[7] It was the first Japanese 4.5×6 SLR, years before the Mamiya M645, and one of the first medium-format SLRs in the world to have automatic exposure. The next year 1968, Minolta also made a prototype SLR in 6×6cm format, the Minolta SR66, having an electronically controlled shutter, perhaps enabling auto-exposure too.
