The Mamiyaflex II is a Japanese medium format twin-lens reflex camera from Mamiya's early 1950s TLR line, predating the later interchangeable-lens C-series. It uses 120 roll film and was positioned as an entry-level fixed-lens TLR for amateur and semi-professional use.

Evidence is thin: the only logged UK auction hammer result is £30 in August 2024, so today's wholesale value for a Mamiyaflex II sits in that low double-digit range at saleroom level. Retail asking prices from dealers will typically run higher once commission, servicing and warranty are added.
