The Silvestri DF7015 Non-Sliding Back Adapter allows their system cameras with the Silvestri-standard 4-point fitting, including the current Bicam, S5 micron, and T30 cameras, to accept digital backs made to fit the Mamiya 645 AFD cameras.
Many manufacturers, from Phase One to Leaf to eyelike and obviously Mamiya themselves, all make or have made digital backs to fit the Mamiya 645 AFD camera system.
As a "non-sliding" model, this back adapter is meant to use live view from the digital back, as opposed to using a ground glass to compose the image and then switching to the digital back such as with the sliding models.
