1.3 Functioning of the camera
The camera consists of two parts: a camera head with lens and an engine with integrated control unit. The camera
head rotates during exposure around its axis, while the engine and control unit remains fixed. Within the camera
head the film transport system is located. When starting the shot, the release opens a small vertical exposure slit
(19). The light that enters through the lens is projected on the cylindrical film plane (20). At the same time, the film
transport system is activated. This device moves the film smoothly from the spool holder for non-exposed film (14)
to the one for exposed film (16). The selected shutter speed defines the rotating speed of the camera.
1.4 Lenses
1.4.1 Lens mount
The camera has been conceived as a compact medium format camera and has been designed for a focal length of
28mm. The parameters for nodal point, length of film and exposure are defined exactly for a focal length of 28mm.
Important: Use only lenses with a focal length of 28mm!
Other focal lengths would require other parameters and would yield, with this camera, distorted and unsharp images.
Important: Normal (AF) lenses have a smaller image circle and lose sharpness at the upper and lower edges. The
best results are achieved with shift PC lenses.
Possible lens mounts:
Nikon 28mm
To remove proctecting lid: press lens button (3) in. At the same time move protecting lid counter-clockwise until its
