This camera is a scaled down version of the larger 5 x 4in camera. It is constructed in the same way and has all the same movements and features found in its larger brother. Although designed for use with the Mamiya RB roll film back it will take other makes. Any size from 6 x 6cm can be used without modifying the design. The camera has a maximum extension of about 26cm. The lens board is 7.5cm square and will take most lenses which use a 0 size shutter. This camera is one of the very few on the market that takes roll film and yet has a full range of movements. It weighs about 1.4kg without lens, shutter or roll back.
