Mamiya's original interchangeable-lens 6x6 TLR from the early 1950s — the Mamiyaflex Automat series, predecessors to the C220 and C330.
The Mamiyaflex is a 6×6 medium format twin-lens reflex (TLR) camera from Mamiya — one of the earlier TLR designs in Mamiya's lineage before the more refined Mamiyaflex C series. Mamiya TLR cameras (C3, C33, C220, C330) are distinguished from other TLR designs by their interchangeable lens system — a unique feature among TLRs, as most (Rolleiflex, Yashica-Mat) use fixed lens sets.
6×6 medium format TLR, Mamiya TLR-mount (interchangeable lens pairs), 6×6 format, waist-level viewing, mechanical leaf shutter in lens, manual exposure. Lens sets include taking lens and matched viewing lens.
The Mamiyaflex TLR system's interchangeable lens capability is the key practical distinction from other TLRs — Mamiya offered lens pairs from 55mm to 250mm, enabling focal length versatility impossible on fixed-lens TLRs. The TLR form factor provides waist-level composition on a large 6×6 negative with minimal camera-to-subject interaction at waist level. This is suitable for street, documentary, and portrait photography.
Test film transport and frame spacing. Verify leaf shutter in the taking lens at all speeds. Test taking and viewing lens focus coupling accuracy (the lenses must focus simultaneously and accurately). Inspect both lens elements for haze. Check the Mamiya TLR lens attachment mechanism if this is an interchangeable lens body. Test waist-level viewer folding and screen clarity.
