The Mamiya 645 80mm f/4 Macro is a normal-focal-length macro lens for the Mamiya 645 medium-format system, designed for close-up work as well as general photography. As a Sekor for the 645 mount, it pairs with bodies in the 645 line and provides a standard angle of view on the 6x4.5 format.

Sales data for this lens is thin: a single UK auction hammer result from April 2024 saw a copy sell for £90, which sets the only firm reference point for what the lens is worth at saleroom level today. With just one data point, that £90 figure should be treated as indicative rather than a true median, and clean, fungus-free examples with smooth focus may price higher when they appear. Buyers should remember these are wholesale hammer figures, so retail dealer asking prices typically sit above this level.
