Mamiya ZDb Digital Back Debuts at Photokina 2008

Cologne, Germany – September 2008Mamiya Digital Imaging has announced the next model of their digital back – called the Mamiya ZDb 22 megapixel Digital Back – will be shown at Photokina 2008. To further refine the successful Mamiya ZD Digital Back system, the R&D team at Mamiya has developed the new ZDb Digital Back with several useful enhancements.

To allow longer shooting sessions, the ZDb will have a buffer with up to twice the memory of the original ZD Digital Back – this means that you can continuously shoot up to 22 frames of full resolution RAW files before the buffer is full. The new back is now compatible with SDHC (Secure Digital High Capacity) cards that can store up to 32 gigabytes of images. The Mamiya ZDb Digital Back can also use SD, SDHC, CF I and CF II cards.

When used with the new Mamiya 645AFDIII, the ZDb Back will display the camera’s 35 custom function controls on the LCD panel. This will make custom camera settings fast and user-friendly. In addition, a beta version of the new Mamiya Remote Capture software will soon be downloadable from our homepage, This software makes shooting tethered with the Mamiya ZDb Back faster and easier.

Boasting a 22 mega pixel Dalsa CCD sensor at an affordable price, the ZDb Digital Back allows the Mamiya 645AFDII, Mamiya 645AFDIII, RZ67Pro-IID and RB67Pro-SD to take razor-sharp digital images - transforming professional quality film cameras into high-end digital systems.

Pricing and delivery will be announced in the fall of 2008.
