Mamiya has introduced an integrated medium-format digital SLR camera, the Mamiya ZD. The built-in 22-megapixel, 36-by-48mm Dalsa CCD imaging sensor is nearly three times as large as a full-size 35mm D-SLR sensor. The 14-bit analog-to-digital converter records information as 12-bit-per-color channel for color accuracy. Data transfer from the sensor is processed with Mamiya's Application Specific Integrated Circuit, with a frame capture rate of 1.5 fps.

With its built-in SD and CF media storage card choices, the Mamiya ZD can be used in the studio or wirelessly on location. The camera incorporates a 645AF interchangeable lens mount design. The sensor size of the Mamiya ZD is nearly equal to a 6x4.5-inch film format, which allows use of the full range of wide-angle to telephoto lenses.

To complement the Mamiya ZD, Digital PhotoStudio software has been developed. It offers image capture, editing and processing in both Mac and Windows. With a FireWire connection (IEEE1394) cable, many of the camera's functions and controls may be selected and set via computer.

Mamiya also has released the ZD digital back, designed for the Mamiya 645AFD and the new RZ67 Pro IID medium-format film cameras. The digital back has a built-in 22-megapixel, 36x48mm Dalsa CCD imaging sensor. The 14-bit analog-to-digital converter records information as 12-bit-per-color channel and has a frame capture rate of 1.2 fps.

With its built-in SD and CF media storage card choices, the Mamiya ZD digital back can be used on location or in the studio. The built-in 1.8-inch LCD screen and mode buttons are located on the back. Using Mamiya Serial Communication data transfer, all necessary data, such as storage space, battery status, exposure data and capture status, are displayed in the viewfinder and main data display of the 645AFD.

The ZD SLR camera will be priced $10,000 to $15,000. The ZD digital back price has yet to be determined.
