The New M Series Digital Backs M18, M22 and M31


June, 2009: Mamiya Digital Imaging is proud to announce our new M series digital backs, consisting of three new models: the M18, M22 and M31, the latest additions to our digital line-up.

The M series digital backs have all been designed for compatibility with Mamiya's 645AFDIII. Through use of the specifically designed digital back adapter HX701, the backs can also be attached to our famed RZ Pro IID.

The M18 has a resolution of 18 megapixels and a CCD size of 44.2 x 33.1mm. The M22 has a resolution of 22.1 megapixels and a CCD size of 48.9 x 36.7mm while the M31 has 31.6 megapixels and a 44.2 x 33.1mm CCD. These large sized CCDs make the digital backs ideal for medium format photography. Each digital back can be purchased separately or in a system kit with the Mamiya 645AFDIII camera and Sekor 80mm F2.8 D lens. The M series backs are the quintessential tool for commercial photographers and studios, covering portraiture and on location work.

M18: The new Mamiya M18 digital back features one of the fastest capture rates of any medium format system, up to 72 frames per minute sustained depending on camera settings and storage medium. The highly versatile M18 combines easily manageable file sizes with full 16-bit capture and 12 stops of dynamic range, producing images of extraordinary quality which no DSLR can equal. With an ISO range from 100 to 800, and exposure times up to one-hour duration with Xpose+ technology, the M18 is one of the most versatile digital backs available today.

M22: The M22 digital back features a nearly full-frame 22MP CCD producing images of breathtaking clarity and sharpness with virtually negligible effect on lens focal length. With an ISO range from 50 to 800, 16-bit capture, 12 stops of dynamic range and exposure times up to one-hour duration with Xpose+ technology, the M22 is ideally suited to commercial photography both on the AFD III or when mounted on a view camera.

M31: The new M31 digital back combines high resolution captures of 31MP with fast shooting speed of up to 45 frames per minute sustained. Perfect for fashion or field photography, the M31 has high ISO capability up to 1600, 12 stops of dynamic range and exposure times up to one-hour duration with Xpose+ technology. With powerful moiré control, the M31 is ideally suited to fashion and portrait photography, whilst the high resolution 31MP captures make it the ideal back for commercial applications also.
