The Mamiya Camex-Six is a Japanese medium-format folding camera from the post-war era, designed to produce 6×6cm negatives on 120 roll film. It belongs to the early phase of Mamiya's output, when the company built folders aimed at amateur and semi-professional users.

Evidence of value is thin: a single UK auction-hammer record from Christie's in 2006 places the Camex-Six at £120, and no more recent saleroom results are available to confirm what one is worth today. With only one wholesale data point and no contemporary sales, any current price guidance for what a Camex-Six sells for in 2026 should be treated as indicative rather than firm.
