The Mamiya M645 Super (1985) is the second-generation professional model of the Mamiya 645 system, replacing the M645 1000S. Its most significant addition over all previous M645 bodies is the interchangeable film magazine -- photographers can now swap between 120 and 220 backs mid-roll, or carry dedicated backs pre-loaded with different film stocks. The Super also introduced shutter-priority automatic exposure alongside the existing aperture-priority and manual modes, and moved to AA batteries. It accepts the full range of Mamiya 645 Sekor C lenses without modification and remains mechanically compatible with all earlier 645-mount glass.

After a decade of the original M645 family, Mamiya redesigned the system for the Super. The most requested professional feature was interchangeable film backs -- a staple of Hasselblad V-series cameras -- and Mamiya delivered it here at a substantially lower price point. The shutter-priority mode added flexibility for photographers working in mixed lighting conditions who needed to lock shutter speed rather than aperture. The battery change from button cells to AA alkalines improved reliability in cold conditions. The Super was itself succeeded in 1992 by the M645 Pro, which refined the design with TTL flash metering and ergonomic improvements, though the two bodies are functionally close.
The interchangeable back was a professional threshold feature. Before the Super, M645 users had to finish a roll before switching film -- a significant constraint in studio or assignment work. With the Super, a photographer could carry backs pre-loaded with tungsten-balanced, daylight, and push-processed stocks and change them between shots. This brought the M645 system operationally in line with Hasselblad and Bronica SQ workflows at a more accessible price. The Super is also frequently praised for the quality of Mamiya's SPD metering, which handles mixed and difficult light reliably. The shift to AA batteries means the Super remains practical today without hunting for obscure cells.
