Mamiya M645
The Mamiya M645 is the first series of 4.5×6 SLRs made by Mamiya. The finder is interchangeable, but there is no magazine back, only preloadable film inserts. All the M645 models share the same accessories (finders, lenses, grips and inserts). The lenses and inserts can also be attached on the later Mamiya 645 models.
The original M645 appeared in 1975. It has knob advance and shutter speeds from 8s to 1/500.
The M645 1000S (1976) adds the 1/1000 top speed, a selftimer, a depth of field preview and other details.
The M645 J (1979) is like the original model with shutter speeds from 1s to 1/500 and with some other features removed.
