The Mamiyaflex C is a medium format twin-lens reflex camera taking 6x6cm frames on 120 roll film. It was the first in Mamiya's interchangeable-lens TLR line, introducing the bellows-focusing body that the later C-series (C2, C3, C220, C330) would refine.

Sales records for this model are very thin: the two UK auction hammer results on file are £74 (1999) and £129 (2002), so any current value figure should be treated as indicative rather than a reliable guide to what one is worth today. As a wholesale saleroom price (excluding buyer's and seller's commission), a clean working example would likely sell for a similar two-figure to low three-figure sum in 2026, with condition of the bellows, shutter and lens being the main factors that move the price.
