The Mamiya 645 80mm f/2.8 is the standard normal lens for the Mamiya 645 medium format system, covering a 6x4.5cm frame with a field of view roughly equivalent to a 50mm on full-frame 35mm. It was designed as the kit lens for the 645 line and is the most commonly encountered focal length in the system, used for general, portrait and reportage work.

Auction data for the 645 80mm f/2.8 is thin: a single UK saleroom hammer result in October 2025 closed at £126, which is the only verified data point we hold as of 2026. Because this is a wholesale auction-hammer price (excluding buyer's and seller's commission) rather than a dealer asking price, retail value at a shop will typically sit higher; with only one sale on file, treat £126 as an indicative rather than a representative figure for what the lens sells for.
