Phase One and Mamiya Digital Imaging Introduce the World’s
Most Flexible Open Medium Format Digital Camera Platform

Platform designed for more flexibility, higher quality system options

PHOTO IMAGING EXPO, TOKYO, 19 March 2008 — Phase One A/S and Mamiya Digital Imaging Co., Ltd. today unveiled the world’s most flexible, open medium format digital camera platform. Known as the Phase One 645 Camera or the Mamiya 645AFDIII, the co-developed platform will be sold exclusively by Phase One and Mamiya respectively.

The camera platform answers the calls of professional photographers for a modular system that offers unprecedented feature combinations, and most significantly the freedom to choose individual components from an open platform to best serve their working needs.

Designed to accept all quality digital camera backs, the camera platform is also open for traditional film operation. It offers the widest choice of high-end lenses, including the complete Mamiya 645 lens range, the new 28mm aspherical and D series lenses, as well as Hasselblad V-lenses and Pentacon Six lenses. It is designed to achieve shutter speeds from 1/4000 sec. to 60 min. The camera features an ergonomic molded grip and provides direct control of critical camera settings using manual dials -- both of which are essential elements for the professional photographer engaged in day-long hand-held shooting sessions.

“Phase One and Mamiya have taken the first step in delivering a unique approach to designing camera systems,” said Henrik Håkonsson, CEO of Phase One. “We believe that equipment interoperability and personal choice are integral values in realizing the highest quality imaging results. Furthermore we have invested heavily in optimizing all elements of the camera systems reliability to maximize the photographers’ time for shooting extraordinary images.”

Mamiya Announces New 645AFDIII

Elmsford NY, March 19, 2008 -- Mamiya has announced an exciting new addition to their professional line of medium format film/digital cameras – the Mamiya 645AFDIII.

“The Mamiya 6454AFDIII builds upon the Mamiya 645AFDII’s success,” states Jeff Karp, Mamiya Marketing Product Manager. “The enhancements in the 645AFDIII camera take us to an even higher level of compatibility and performance with digital backs and lenses.”

The 645AFDIII’s updated intercommunication protocol MSCE (Mamiya Serial Communication for External), provides increased information transfer between the digital back and the camera body, making data transfer fast and reliable.

The Mamiya 645AFDIII employs a new, powerful and silent coreless motor that makes auto focusing faster and quieter than ever before. To further improve focusing control, the focusing point is user-selectable and can be positioned in the center, right or left side of the screen or set on “auto” to let the camera select the focus point.

The new Sekor AF 80mm f/2.8D lens introduced with the 645AFDIII is equipped with an auto/manual focus switch ring that allows fast one-touch selection of auto or manual focus mode. Consistent with all new lenses being developed for the D range, the new 80mm lens contains a 16bit CPU. The 16bit CPU is advantageous for easier firmware upgrading, finer lens characteristic correction and faster, more reliable communication between the lens and the camera body.

The Sekor AF 80mm f/2.8D has a lens barrel cover made of turned aluminum treated with black alumite, replacing the former lens' black polycarbonate plastic cover. This gives the lens a better appearance and texture and adds to its professional feel.

For film use, the new AFDIII with HM402 Film Back employs a powerful coreless motor and achieves a winding speed of 2 frames per second when used in conjunction with the 645AFDIII (instead of 1.2fps with Film back HM401 on the AFDII). In addition to exposure mode, aperture value, shutter speed, exposure compensation value, bracketing position, metering mode, etc., the focal length of the lens in use can now be imprinted on the film edge.

In response to requests from customers for compatibility with rechargeable batteries, the 645AFDIII can also accept nickel-metal hydride AA batteries in addition to the alkaline or lithium AA batteries. The 645AFDIII also allows photographers to select 2nd curtain flash synchronization for creating unique flash photography.

Thanks to Mamiya’s continuing open platform policy, the 645AFDIII is also compatible with digital backs from other makers such as Leaf and Phase One.

The Mamiya 645AFDIII will be available June 2008.
