b. Shutter.
The shutter has five automatically timed speed settings
(1/50, 1/25, 1/10, 1/5, 1/2 sec.), plus time (T), bulb (B), and seven aperture
settings (f/6.3, 8, 11, 16, 22, 32, 45). The shutter also contains an internal
synchronization mechanism and a press focus lever to open and close the shutter
to facilitate focusing.
c. Lens board.
The lens board is provided to permit mounting the lens
assembly in the front frame of the camera. The front vertical movement plate
with the threaded shaft and shaft support, and the front horizontal movement
plate with the vertical gear and rack gear, shift the lens board and lens to
position the image on the ground focusing glass.
d. Cable release. The cable release is provided for remote operation of
the shutter, to permit making T, B, or instantaneous (I) exposures without
jarring the lens or causing camera movement.
