The Konica 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 (1–1000, B), and through-the-lens metering for shutter-priority automatic exposure. The design allowed for interchangeable lenses and finders; the camera has been photographed and exhibited with a pentaprism finder and an f/2.8 standard lens.
The Konica SF never went into full production. It was the first Japanese 4.5×6 SLR, and one of the first Japanese medium-format cameras to have automatic exposure. The same year 1967, Minolta also made a prototype auto-exposure SLR in 6×6cm format, the Minolta SR66.
