The Mamiya 7 65mm f/4 is a moderate wide-angle lens for the Mamiya 7 medium format rangefinder system, designed for landscape, environmental portrait and travel work on 6x7 film. It uses the bayonet mount specific to the Mamiya 7 and 7 II bodies and is not interchangeable with RB67, RZ67 or 645 systems.

Recent UK saleroom evidence is thin: a single hammer result of £403 at Chiswick Auctions in October 2025 sets the only verified data point, so today's market value sits around that level for a working copy at auction. Hammer prices reflect wholesale results before buyer's premium and exclude dealer retail margins, so clean, boxed examples typically sell for more in the dealer market than the figure shown here. With one sale on file, the price range and median both rest on that £403 result; expect spread either side as more 2026 auction data emerges.
