Film Capacity

100ft (30m) and 50ft (15m) daylight loading spools of 16mm film

Threading

Automatic threading and loop forming. The end of the film is simply placed in a channel leading to the feed sprocket. The release is pressed and the film is then automatically threaded throughout the entire mechanism

Motor

Constant speed, spring motor mechanism; governor controlled. Large winding handle folds downward and attaches to camera when not in use. Spring cannot be over-wound. 8:1 external drive shaft permits the attachment of an electric motor

Turret

Rotating turret accommodates three interchangeable C mount lenses. The top position allows for critical focusing through a groundglass screen on later versions of this model

Viewfinder

Accessory Tri Focal viewfinder gives an exact viewing field for lenses of 3 focal lengths. Later versions of this model had a built-in critical focus viewer with optional cupped eyepiece

Variable Speed

8, 16, 24, 32 and 64 frames per second with the ability to change speeds while the camera is running

Release Button

Provides for the making of continuous exposures by a finger-tip release on the front of the camera. A side release allows for locked, hands-free running or single frame exposures

Footage Counter

Adds and subtracts accurately in forward or reverse motion and automatically returns to zero when film is reloaded into the camera

Audible Footage Indicator

A distinct click announces the passing of each 10 inches of film through the gate. This mechanism may be disengaged, if desired, by simply moving a lever

Frame Counter

An accessory frame counter could be attached to the motor crank shaft. Two separate counters registered increments of single frames and 50 frames as the film progressed

Single Frame

Time lapse and animation is possible by using the side release button or an accessory cable release and adapter; I-T lever allows for timed or instantaneous single exposures

Manual Rewind

Clutch disengages spring motor and permits forward movement and backwind without running down the spring; allows for dissolves and superimposition

Tripod Socket

3/8" thread
