Mamiya 45mm f/2.8
The Mamiya 645 45mm f/2.8 is a moderately wide-angle prime designed for the Mamiya 645 medium format SLR system, where its 45mm focal length covers a noticeably broader field than the 80mm standard lens. It was built for landscape, environmental portrait and interior work on 6x4.5 film, with an f/2.8 maximum aperture giving a usable viewfinder image even in dimmer conditions.
Hammer prices at UK auction have been modest for this lens, with a recorded 2025 sale fetching £100 at saleroom level, which gives a working reference for what a usable copy is worth in today's 2026 market. With only a single tracked result the price band is narrow, and clean examples with their caps and a clear front element typically sell for a small premium over scruffier copies. Buyers should remember these figures are wholesale auction hammer levels rather than dealer retail asking prices.
