Mamiya M645 Medium Format Camera Body Review

The Mamiya M645 is a classic medium format camera body that shoots 645 format (6x4.5cm) on 120 film, offering a larger negative than 35mm while maintaining relatively compact dimensions for a medium format system. This used body is available through KEH in varying conditions from bargain to excellent, with some units including the 120 film insert. At $123 MSRP for a used body, it sits in the affordable entry tier for medium format film photography.

The M645 system is known for its modular design, allowing photographers to swap film backs, finders, and motor drives. It uses a focal plane shutter and supports a wide range of Mamiya 645 mount lenses. As a used camera from an older system, prospective buyers should verify mechanical condition, light seals, and shutter function before purchase. The camera requires manual metering or an external meter in most configurations, making it best suited for those comfortable with film fundamentals and willing to work within the constraints of older gear.
