Description — Mamiya 645
The Mamiya 645 is a film-based medium format camera built for photographers who work with analog emulsions and value a modular, interchangeable system. The body is constructed from aluminum alloy with a leatherette covering, measuring 113 x 123 x 84 mm and weighing 920g — a manageable size for a medium format system. The camera accepts interchangeable viewfinders, with support for both waist-level and prism finder configurations, allowing photographers to adapt their working style to the subject.
Film ISO sensitivity spans 25 to 3200, giving users broad compatibility with available film stocks. Flash shooting is well supported, with PC sync terminals for both X and FP flash types and synchronization at 1/60s. Focusing is manual only, centered on a single point, placing full compositional and technical control in the hands of the photographer.
Metered prism finders require a PX28 6V or 4SR44 6V battery. There is no weather sealing, no image stabilization, and no digital connectivity — the Mamiya 645 is an analog tool designed with simplicity and reliability at its core.
