Weight

Approximately 2 lbs.

Outer Case

Highly polished duraluminium body, covered in genuine Morocco leather. Metal parts are chrome-plated.

Film Capacity

25ft daylight loading spools of double run 8mm film. When a roll runs through the camera, only half the width of film is exposed. The spool is then reversed and run through again, exposing the other half. When processed, film is split and spliced together giving 50' for projection. Projection time at 16 fps for 25' roll is 4 minutes.

Threading

manual, with no loop forming; with the pressure pad opened the film is simply placed over a guide roller, threaded behind the gate, over the bottom guide roller and onto the takeup spool.

Motor

Constant speed, spring motor mechanism; governor controlled. Generous winding key, attached to the camera, folds back against its side when not in use. Spring cannot be over-wound.

Zoom Lens

SOM Berthiot Pan Cinor 8-40mm f/1.9 zoom lens

Viewfinder

Reflex viewfinder with built-in split-image rangefinder; Adjustable diopter for eyesight correction; Rubber eyecup.

Variable Speed

12, 16, 18, 24, 32, 48 and 64 frames per second.

Release Button

continuous exposures can be made by a finger tip release button or cable release. Running operation can be locked to prevent accidental exposures. Tightening the cable release screw allows for hands-free filming.

Variable Shutter

Adjustable dial changes the shutter opening from 0-165 degrees to allow for shortened exposure times and fades.

Footage Counter

Precise reading of exposed film footage. Resets to zero upon reloading.

Single Frame

A cable release socket allows the user to expose single frames for filming animation, titles, etc.

Manual Rewind

A small hand crank allows for rewinding film up to 60 frames.

Exposure Meter

A battery powered (Mallory RM450) cadmium sulfide photo-resistive cell measures light through the lens. A film speed sensitivity dial (10-400 ASA) is then set and a needle indicator in the viewfinder is centered by adjusting the lens diaphragm, resulting in correct exposure.
