Minolta SR66
The Minolta SR66 (ミノルタSR66) is a 6×6 SLR camera made as a prototype by Minolta in 1967. It has exchangeable film backs for 120 or 220 film, and an electronically governed metal focal-plane shutter. The sources are unclear about whether this means auto-exposure or not. The design allowed for interchangeable lenses and finders; the camera has been photographed and exhibited with a "waist-level" finder and a standard Auto W-Rokkor lens. It was displayed at the JCII exhibition about Konica and Minolta in 2005; pictures taken at this event show what looks like three interchangeable lenses, in addition to the standard lens mounted on the camera.
The Minolta SR66 never went into full production. The same year 1967, Konishiroku also made a prototype auto-exposure SLR in 4.5×6cm format, the Konica SF.
