The fixed disk I is mounted on a bolt a at the top of the camera and contains an opening b, which is positioned opposite the lens. The second disk is revolubly mounted on the same bolt a and has four rectangular openings c adapted to take the dark slides and focusing - screen. The outside flanges of the disks overlap and are padded to make a lighttight connexion, and the dark slides are registered in position by catches and notches. Alternatively, the holder may be mounted on a frame which fits into the usual guide flanges on the camera back.
