A Cambo Wide to Mamiya 6×9 roll film back. We used an existing mounting plate for the Mamiya Back plate. The Mamiya mount attached directly to a custom SKG plate. The adapter is completely removable, requiring only three locking levers to mount the roll film and lens board. A special gloove on the side of the adapter allows the "S" shape of the Mamiya back to locate close enough to the lens for proper infinity focusing.
