Features
The Mamiya 645DF is a camera body designed for use with digital backs.

Compatibility with these essential accessories means all of the needs of the professional photographer have been covered.

Mamiya Sekor AF 80mm F2.8 LS D Lens (prototype)

Features
The Mamiya Sekor AF 80mm F2.8 LS D lens is the first leaf shutler lens in Mamiya’s AF lineup. The leaf shutler, which has been developed and manufactured in-house, is capable of shutler speeds from 1/500 second to 16 seconds, and has flash synchronization at all speeds. It allows more control for on-location daytime shooting where flash synchronization is required, as well as for flash photography in studios. The lens has been designed for easy and simple operation in conjunction with the focal-plane shutler system of the Mamiya 645DF. The lens has angle of view of 47 degrees in the 6×4.5 format, the equivaient of a 50mm lens in the 35mm format. As the occurrence of aberration is minimal and balance is of high quality, natural depictions are consistently achieved. Switching between manual and auto focusing is controlled by simply moving the focusing ring back and forward.
