Phase One Medium Format Digital Camera Solutions

Phase One 645DF Medium Format Digital Camera

COPENHAGEN, September 28, 2009 – Phase One, the world’s leader in open-platform medium format camera systems and solutions, today announced 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. 

Phase One 645DF Camera - Front 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 (see today’s related announcement).

“Our patent-pending flash sync breakthrough eases working with wide open apertures and fill-in flash on location,” said Jan H. Christiansen, Phase One marketing director. “We already offer the most flexible exposure times ranging from 1/4000 of a second to one full hour. Setting new performance standards is all about expanding creative options for photographers.”

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 ultrafast 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.

Freedom to choose the best back for you
Phase One builds flexible, open photographic systems to support a professional’s style, needs and working preference. The Phase One 645DF camera supports the world’s finest digital backs, ensuring freedom of choice and investment protection for years to come. It is compatible with digital backs designed for the Phase One / Mamiya AFD mount, including backs from Phase One, Leaf, Mamiya and others.

Pricing and Availability
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. All equipment can be ordered now from Phase One and Leaf dealers.


The Phase One P 30+ Camera System is designed to be a seamless extension of your creativity. Extraordinary capture becomes natural through ease of use and direct control. Shoot digital or film with no lens or back restrictions. Take advantage of the Phase One digital lenses or use your Mamiya 645 AF/AFD or Hasselblad V lenses for an even broader choice.

The fast capture rate and powerful moire control makes the P 30+ digital back an invaluable tool for high fashion and people photographers. Combine this with 31 mega pixel captures and unfailing performance and you have an incredibly strong partner for any challenge. In addition, the capacity to shoot at up to 1600 ISO allows you to capture in extremely low light situations.
