The Credo 40MP Digital Back with Mamiya 645DF Mount from Mamiya Leaf enters the marketplace as the new standard for professionals who demand the most from their work and from their equipment. The 40MP digital back is the fastest of Mamiya Leaf's impressive new Credo line of medium format digital backs and brings with it the tradition of Mamiya quality and the level of innovation that maintains Mamiya Leaf as a leader in digital photography.

A custom-built DALSA CCD sensor provides unmatched detail in a single shot image with gorgeous tones, accurate colors and ultra low noise. This state of the art sensor measures 43.9 x 32.9mm with a crop factor of 1 to 1.3 and provides an unsurpassed dynamic range of 12.5 f-stops and a full resolution capture rate of 1.2 frames per second.

A new generation of display technology has been designed for the Credo line ensuring quality preview and ease of control. The 3.2" touch screen with up to 16 million colors provides accurate verification of colors, shadow details and focus and the bright 1.15MP screen with 170° viewing angle allows for improved viewing in challenging light. Its intuitive graphical user interface (GUI) means more efficient browsing and smart navigation and the touch screen controls extend beyond the LCD to keep the viewing area clean of fingerprints and smudges.

Continuing their partnership with Phase One, the Credo back offers Capture One workflow software to seamlessly edit, enhance and present images and, with Capture Pilot, you (or your client!) can immediately preview images with an Apple iPhone or iPad and remotely control your camera. Mamiya Leaf is presently working with Adobe to ensure that one of their future versions of Lightroom or Photoshop will support the Leaf Credo IIQ RAW files.

Improving portability and speed were paramount when Mamiya Leaf designed the Credo line. Utilizing a new, faster dual core microprocessor and the latest CF technology has improved capture and viewing rates and USB 3.0 and FireWire 800 technology ensure the fastest possible transfer speeds. Lossless 16-bit file compression accelerates file handling without loss of image quality. An internal battery charger will keep you always ready to work un-tethered and the brilliant LCD with Live View allows for clear focus and composition on the go. Weather-sealed construction offers peace of mind when shooting in less than optimal conditions.

This is the fastest and most affordable Credo digital back and with a commitment to quality on your part, you will be rewarded with long product life, dedicated customer service, high resale value, an industry leading upgrade program and a digital back that is compatible with more than 80 cameras, including other Mamiya models and cameras by Contax, Hasselblad, Bronica, Rollei, Sinar and more.
