About Mamiya/Leaf

Responding to the demands of medium format film and digital shooters, Mamiya has incorporated the latest auto focusing technology into the 645AFD III. The Mamiya 645AFD III employs a new, powerful and silent coreless motor that makes its auto focus system faster and quieter than ever before. A new focusing algorithm provides precise focusing under a wide range of lighting situations.

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 can be set on "auto" to let the camera focus on the closest subject. Mamiya pioneered the world's first true cross-platform film or digital camera and includes its latest MSCE (Mamiya Serial Communication for External) data transfer technology in the 645AFD III.

All critical exposure and shooting information is internally exchanged between the camera and compatible digital camera backs. Whether you're shooting film or digital, it's the most affordable and technologically advanced medium format camera available. The 645AFD III is loaded with 36 custom functions. Individual camera preferences such as 1/3, 1/2 or full aperture/shutter speed increments, flash synch speed, dial functions, exposure compensation increments, bracketing sequence, dial direction setting and much more are easily set and recalled in a snap. In addition, separate user configurations can be set and recalled on-the-fly when several photographers are using the same camera.

Dedicated "Quick Action" buttons have also been designed into the 645AFD III for fast activation of such functions as multiple exposures, auto-bracketing, key lock, auto exposure lock and auto focus lock. The Mamiya 645AFD III combines sophisticated advanced features, integrated microprocessor controlled electronics, enhanced performance and the quality of medium format film or digital capture with the power of proven World-Class Mamiya autofocus optics.

Daadorama W  How much are the backs?

Shopper  Hi Folks, I'm trying to go digital (am a Newbie), but also retain film option, w/out spending $$thousands. I'm a film-pro, thinking of getting back in biz (journalism, portraits, weddings, architecture, small product). Personal shooting (landscape/macro, wildlife, family events). Would like ability to shoot video. Can this AFDIII kit also be used for film? Can I use manual lenses on any AF or AFD body? My present kit: 2 Mamiya m645 1000 S bodies, Mamiya Sekor C manual lenses (55, 70 LensShutter, 150/all f2.8), Prism Finder PDS AE . Also considering Canon DSLR w/Full-frame CMOS sensor & Mamiya lens adapter. Any suggestions on best Mamiya kit combos & Canon's 50/60D, 5D/II/III or 7D systems would be much appreciated! Tx so much, J.J.
Andrew R  This body is initially sold as a film body, though I believe digital backs are available. I don't believe that the digital backs are video capable (though that may vary depending on the model) medium format digital backs tend to operate at a slower framerate than their DSLR cousins. The AFD III will mount both AF and MF lenses, though some lenses might not be fully compatible. For the record most lens adapters are dodgy. Depending on the body you choose (Canon especially) some adapters may require additional optics to allow for infinity focus. This may hamper lens performance. If video is a requirement, a high end full frame DSLR may be the better option.
