The Mamiya 645 AF (1999) is Mamiya's autofocus 6×4.5 medium-format SLR — separate body design from the manual-focus 645 Pro line. 3-point autofocus, full PASM modes, 1/4000s shutter, 1/125s flash sync, AA-battery powered. The body and lens system uses a different electronic protocol than the manual-focus 645 Pro line — manual 645 lenses do NOT autofocus on AF bodies (and vice versa, AF lenses don't focus on Pro bodies). After Mamiya's merger with Phase One (2009), the AF line continued as the Phase One 645DF / DF+ / XF — the same body family with digital backs.

Iterations:
After 2009, the body became the Phase One 645DF (a similar body sold for digital backs) and continued evolving into the Phase One XF system used today with Phase One IQ digital backs.
The 645 AF is the cheapest medium-format autofocus film body. Used at $600–1,500 — comparable to a Pentax 645N but with a wider lens system that includes both Mamiya 645 AF lenses and (via adapter) Phase One Schneider Kreuznach lenses for digital users.
For 2026 buyers, the 645 AF is the rational choice if you also have access to a digital back — the body switches between film and digital work seamlessly. The trade-off vs the Pentax 645N is the heavier body and the more complex lens-mount system.
Mamiya 645 AF lenses (D variants): 80/2.8 D (kit), 45/2.8 D, 55/2.8 D, 150/2.8 D, 210/4 D, 35/3.5 D wide. Manual-focus Mamiya 645 lenses (older M645) physically mount but do NOT autofocus. 120/220 backs, Phase One digital backs (P25, P30, P45+, IQ-series).
