The motorised 6x8 roll film back for the Mamiya RB67 Pro-S/Pro-SD was a versatile and very precise roll film back. The photographer could use both type 120 and type 220 films. Should the 4xAA standard batteries ever run out, manual film transport was also possible at any time. The ALPA MA adapter had been part of the ALPA platform since 1998 and made it possible to use these backs on any ALPA camera.
