Mamiya M645 1000S

The Mamiya M645 1000S is a medium format SLR that records 6x4.5 cm frames on 120 and 220 roll film. It was introduced in the mid-1970s as an upgraded member of the M645 line, with the "1000S" name reflecting its top mechanical shutter speed of 1/1000s. When new, it was positioned as a more affordable route into system 645 photography than the heavier 6x6 and 6x7 Mamiya bodies.

At recent UK auction, hammer prices for the M645 1000S have spanned roughly £100–£730, with the median sitting around £250 across 2023–2025 sales. Today the bulk of bodies with a standard 80mm Sekor C change hands in the £200–£340 band at saleroom level, while one well-presented outfit in August 2025 reached £725 — a reminder that how much an M645 1000S sells for depends heavily on whether extra finders, prisms and lenses are included. These are wholesale hammer results rather than dealer retail, so the worth of a clean private-sale example typically sits above the figures shown.
