The Mamiya 645 camera systems are a series of medium format film and digital cameras and lenses manufactured by Mamiya and its successors. They are called "645" because they use the nominal 6 cm x 4.5 cm film size from 120 roll film. They came in three major generations: first-generation manual-focus film cameras, second-generation manual-focus film cameras, and autofocus film/digital cameras. The M645 1000S was manufactured from 1976 to 1990. This camera added a 1/1000 second shutter speed to the M645, as well as a self-timer and a depth-of-field preview lever. The standard lens was the 80mm f/2.8 C or the 80mm f/1.9.
