Key Features

Roll Film Back Design
The Zenza Bronica GS-1 645 Film Back is a interchangeable magazine designed for the Bronica GS-1 medium format SLR system, producing 6x4.5 cm frames on 120 or 220 roll film. Its quick-release mounting plate allows the back to be swapped mid-roll without advancing the film, a design feature standard across the GS-1 system's modular back lineup.

Dark Slide Safety Mechanism
A removable dark slide inserts into the back to block light from reaching the film plane, allowing the magazine to be detached from the camera body even with an exposed roll loaded. This safety interlock is a defining feature of professional medium format film backs of this era, preventing accidental exposure during mid-roll back changes.

645 Format on the GS-1 Platform
Unlike the 6x7 cm format native to many Bronica GS-1 accessories, this back is configured for the 645 (6x4.5 cm) frame size, yielding a greater number of exposures per roll while remaining compatible with the same GS-1 body mount and back-release mechanism.
