Description — Mamiya M645
The Mamiya M645 is a medium format SLR film camera produced during the 1970s, built around the Mamiya 645 lens mount. It accepts both 120 and 220 film, offering photographers a choice in roll length depending on the demands of their shoot. A focal plane shutter handles exposure, and the system operates entirely on manual focus, keeping the shooting experience deliberate and hands-on.
The body weighs between 1,400g and 1,500g, reflecting the solid, substantial build quality associated with professional medium format equipment of the era. For flash and lighting, the M645 includes both a hot shoe and a PC sync port, making it straightforward to integrate with external flash units or studio strobes. The Mamiya 645 lens mount supports a range of interchangeable lenses, spanning brand-specific Mamiya 645 optics as well as compatible third-party glass, giving photographers meaningful flexibility when building out their system.
This is a camera well-suited to film photographers who want a medium format SLR platform with broad lens compatibility and classic manual operation.
