Mamiya 645DF Camera
Mamiya introduces the next level of camera performance for digital medium format photographers – the Mamiya 645DF camera. With autofocus speeds up to 30% faster than previous models, plus a new companion series of leaf shutter lenses, the Mamiya 645DF offers substantial performance upgrades for owners of virtually any brand of digital back, including Leaf®, Mamiya®, Phase One®, and Sinar®.
Combining 35mm handling ease and speed but with an available image capture area almost three times larger, the Mamiya 645DF is a full-featured camera, utilizing digital controls and LCD displays, and featuring 19 custom settings for fully personalized digital photography.
The new 645DF system delivers exciting advances in core-camera technology, including an innovative new selectable dual shutter system. The photographer can now select the best shutter for the conditions – either the integral focal plane shutter, which can be used with any of the 15 existing Mamiya 645AF system lenses, or one of three new lenses containing an integral leaf shutter for flash sync speeds of up to 1/1600 second.

The 645 AFD
lens system offers two ideally matched zoom lenses adding total 35mm format
handling and flexibility to medium format quality. The AF 55-110 f/4.5 zoom
covers the popular 35-70mm zoom range in 35, whereas the AF 105-210mm f/4.5 ULD
is its perfect match covering a 68-130 equivalent range. They both offer a
separate zoom and focus rings, plus the focus ring is a push-pull clutch to
quickly switch between manual and autofocus. These lenses make the 645 AF system
ideal for sports, travel and fast moving portraiture. Optical performance equals
prime focal length lenses due to Mamiya’s high quality computer aided design and
manufacturing.
Applications cover a wide range of subjects including travel, wildlife,
fashion, and landscape photography.
Equivalent to 34-68mm in 35mm format.
