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.
