The Zenza Bronica S is a Japanese 6x6 medium format SLR introduced in the early 1960s, using 120 roll film. It was positioned as a professional studio and field camera offering interchangeable lenses and an instant-return mirror at a lower price point than European competitors of the period.

Sales data for the Bronica S is sparse, with a single recorded UK auction hammer result of around £200 — a wholesale saleroom level rather than a retail asking price. Today in 2026, working examples with a clean lens and functional shutter tend to anchor around that figure, though condition, completeness of the film back, and lens inclusion materially affect what a Bronica S sells for.
