Machined to exactly the same focal plane as a conventional Mamiya film back, the Better Light RB/RZ-67 adapters require no modifications to the camera or scan back for proper operation.

The same lenses used for conventional film shooting are used with the RB-67 and RZ-67 adapters, without any impact on focal length or perspective.

To focus, the photographer can use either the standard Mamiya ground glass or Mamiya 45° prism view finder. After focusing through the viewfinder, the photographer locks up the mirror and opens the camera lens with the bulb setting. Better Light’s ViewFinder™ software package, provided with each scanning back, also features digital focus verification for the ultimate in focusing precision.

With the adapter installed, each of the Better Light digital scanning backs captures the Mamiya’s maximum image area, providing an overall digital image that is approximately 7 cm (2-3/4 in.) square with slightly rounded corners, producing digital files equal to 76% of the file capacity of the Better Light scan back's full capability. A horizontal or vertical image can also be recorded by means of the cropping tools in the Better Light ViewFinder™ capture software.
