Description — Mamiya Pro S
The Mamiya RB67 Pro S is a medium format film camera from the 1970s, built on the Mamiya RB lens mount system. It accepts interchangeable Mamiya RB lenses, giving photographers access to a dedicated range of optics suited to the platform. The camera shoots on 120 and 220 film, accommodating different roll lengths depending on the shooting scenario.
Exposure mechanics are handled by a mechanical shutter, and focusing is manual throughout. For lighting, the RB67 Pro S offers both a hot shoe and a PC sync port, making it compatible with a wide range of flash and strobe systems in studio or field environments. The camera's body weight falls between 2,670g and 3,000g, reflecting the robust, modular construction typical of professional medium format systems of its era.
This is a camera built for deliberate, considered work — most at home on a tripod with careful attention to composition and exposure.
