Phase One has launched the Phase One 645DF camera. Engineered in partnership with Mamiya Digital Imaging for superior quality image capture and ease of handling, it sets a new standard for high flash sync speeds – up to 1/1600 of a second.

Also today, Phase One announced the availability of three new high performance leaf shutter lenses, 55mm, 80mm and 110mm, all f/2.8 and all designed with the Phase One 645DF camera in mind. The lenses are a result of close collaboration with Mamiya Digital Imaging and Schneider Kreuznach.

The 645DF camera is the only 645 medium format camera which supports both focal plane and leaf shutters, expanding photographers’ innovative possibilities by leveraging the two shutter technologies seamlessly for world class photography, whether this involves ultra-fast flash sync speeds or extremely flexible exposure times.

The new camera introduces many performance improvements over its predecessor. Capture responsiveness and autofocus speed is highly improved giving photographers up to 5 times faster performance in a typical fashion set up.

The 645DF also offers a breakthrough workflow improvement — custom-shooting modes. For the first time in a medium-format camera, photographers can “dial up” a pre-defined mode, where the camera is instantly set up for a given shooting scenario, e.g. product, portrait or landscape photography.

Other workflow enhancements include new tactile buttons, a fully sealed eye-cup eliminating ambient light, improved viewfinder masks, and customizable audio feedback e.g. on focus lock. Several custom functions have been enhanced, without compromising simple navigation.

The Phase One 645DF camera body starts at $5990/€4290 and is expected to ship Q4, 2009. The new leaf shutter lenses start at $2490/€1790 and are expected to start shipping Q4, 2009.
