The Mamiya 645 Pro (1992) is a modular 6×4.5 medium-format SLR with a **focal-plane shutter** in the body (not in the lens, like the leaf-shuttered Bronica ETRSi or Mamiya RZ67). 120 / 220 / Polaroid backs; interchangeable finders (waist-level, AE prism, magnifying chimney); Mamiya-Sekor C lenses with focus rings on each lens. The focal-plane shutter caps at 1/1000s and syncs flash at 1/60s — slower than leaf shutters but acceptable for non-flash work.

The Mamiya 645 line started 1975. Iterations: 645 (1975), 645 1000s (1976), 645 J (1977), 645 Super (1985, modular), 645 Pro (1992), 645 Pro TL (1997, with TTL flash and TTL/Auto modes refinements), 645 AF (1999, autofocus, different body design), 645 AFD (2002+), 645 AFD III (2007). Production of film-version Pro TL ended 2006.
The 645 Pro is the cheapest entry into modular Mamiya 6×4.5. A clean 645 Pro + 80/2.8 + 120 back + AE prism runs $700–1,000 in 2026, comparable to a Bronica ETRSi but with focal-plane shutter (faster top speed, slower flash sync). The Mamiya-Sekor C 80/2.8 N is technically excellent.
For photographers who want medium format but don't shoot studio flash regularly, the focal-plane shutter is fine. For wedding/portrait flash workflows, a leaf-shutter body (ETRSi, RB/RZ67) is preferable.
Mamiya-Sekor C lenses (and later N variants): 80/2.8 N (kit), 45/2.8 N, 55/2.8 N, 110/2.8 N, 150/3.5 N, 210/4 N, 300/5.6 N. AE Prism (PD), TTL Prism (P), Power Drive Grip (auto wind), 120/220 backs, Polaroid backs.
