The Mamiya M645 is the first series of 4.5×6SLRs made by Mamiya. The finder and screens are interchangeable, but there is no magazine back, only preloadable film inserts. All the M645 models share the same accessories (finders, screens, lenses, grips and inserts). The lenses and inserts can also be attached on the later Mamiya 645 models.

The M645 1000S (1976) adds the 1/1000 top speed, a selftimer, a depth of field preview button and other details.

Over the decades, Mamiya made several versions of their 6x4.5 camera. The early models were all metal and mostly mechanical, as is the case with the M645 1000s that I am reviewing here. The 1000s is similar to other early Mamiya M645 camera bodies but differs in that it adds a higher max shutter speed and multiple exposure switches.

In later years, the 645 cameras started to reflect the more modern design and use more plastic-based materials. They also began to utilize removable backs, motorized hand grips, more automated exposure prisms, and eventually even autofocus. More than anything, the longevity of the Mamiya 645 speaks to the robust nature of the format. 6x4.5 negatives, after all, allow for relatively small cameras (by medium format standards) while also allowing for negative many times larger than 35mm film.
