The Mamiya 645 110mm f/2.8 is a short telephoto prime for the Mamiya 645 medium format system, sitting roughly equivalent to a 70mm portrait lens in 35mm terms. Designed for portraiture and short tele work on the 6x4.5 frame, it covers the 645 manual focus bodies via the standard Mamiya 645 bayonet mount.

Auction data for this lens is thin: a single UK saleroom result from June 2023 saw a copy hammer at £62, and that figure is the only confirmed wholesale data point we hold today. With just one result on record there is no reliable median or range, and condition, version and the presence of caps or filters can move what a clean example sells for in the auction market well above or below that benchmark.
