The Mamiya 645AFD body differs from the traditional 645AF camera by enabling MSC
(Mamiya Serial Communication) data transfer of all camera functions to external capture
devices including digital backs. The Mamiya 645AF is a Medium Format Autofocus System
for professionals. Mamiya pioneered the 645 SLR system over 25 years ago, and with the
new 645AF, the newest autofocus addition to the system, they continue their long tradition of
expertise and excellence. The Mamiya 645AF offers many new and innovative features
combined with world-class Mamiya performance.
