The Mamiya 645 AFD (2001) is the second-generation body in Mamiya's autofocus 645 line, following the 645 AF (1999). It uses the Mamiya 645 AF mount - an electronically coupled version of the original Mamiya 645 mount that supports autofocus lenses while remaining optically compatible with earlier manual-focus Sekor C lenses via an adapter. The AFD's most significant departure from its predecessor is its acceptance of Phase One and Mamiya-brand digital backs in addition to standard 120/220 film magazines, positioning it as a transitional body for studios moving from film to digital capture. The AFD shipped into the mid-2000s alongside the Phase One P-series digital backs that became dominant in medium-format professional work.

Mamiya launched the 645 AF in 1999, the brand's first autofocus medium-format SLR. The AF introduced the Mamiya 645 AF mount - mechanically similar to the original 645 mount but adding electronic contacts for AF lens communication - and a new family of AF Sekor D lenses. The AFD followed in 2001 with a standardized digital-back interface (Mamiya / Phase One 645 back mount), faster maximum shutter speed (1/4000s vs 1/1000s on the AF), improved autofocus performance, and full multi-mode AE. Subsequent refinements produced the AFD II (~2004) and AFD III (~2006) before Mamiya transitioned to the DF and DF+ bodies in the later 2000s. Phase One's acquisition of Mamiya assets in the mid-2000s shaped the long-term direction of the platform toward the Phase One IQ system.
The 645 AFD arrived at a pivotal moment - when medium-format digital capture became commercially viable but film had not yet disappeared from professional studios. Its dual-mode design let a studio own a single body that could accept a digital back for commercial work and a 120 film magazine for editorial or personal work. This bridging role made the AFD important infrastructure for the transition period. Phase One P20, P25, and P45 digital backs were commonly paired with the AFD body; the combination was standard equipment in advertising and fashion studios in Europe and Japan during the early-to-mid 2000s. The Sekor D AF lens family (45mm f/2.8, 80mm f/2.8, 120mm f/4 Macro, 150mm f/2.8, 210mm f/4) was optically competitive with Hasselblad and Rollei equivalents at lower prices.
Native mount: Mamiya 645 AF (electronic). AF lenses: Sekor D 45mm f/2.8, 55mm f/2.8, 80mm f/2.8, 80mm f/1.9, 120mm f/4 Macro, 150mm f/2.8, 150mm f/3.5, 210mm f/4, 300mm f/4.5 APO. Zoom: Sekor D 55-110mm f/4.5, 105-210mm f/4.5.
