Mamiya M645

The Mamiya M645 is a 6x4.5 medium format SLR introduced in the mid-1970s, using 120 or 220 roll film to produce 15 or 30 frames per roll. It was Mamiya's first camera in the 645 system and was positioned as a more portable, affordable alternative to 6x6 and 6x7 medium format bodies aimed at wedding, portrait and travel photographers.

At recent UK auction, hammer prices for M645 bodies have typically fallen between £110 and £335, with the last two years clustering around a £250–£260 median. Historic results stretch the range to roughly £82–£380 depending on outfit contents and condition, and in 2026 today a clean, working body with the 80mm Sekor C standard lens generally sells for more than a body-only example. Condition of the foam light seals, meter accuracy and the presence of an unscratched waist-level or prism finder remain the main factors driving what an M645 is worth in the saleroom.
