REPORT OF COMMISSION V GV-83 
  
Fic. 4. PhotoMetric camera. 
The camera uses a f/6.3 Ektar lens with an 83 inch focal length. The lens 
is set for a subject distance of 30 feet 5 inches. The lens diaphragm is locked at 
f/8. A 23 by 3i inch negative is provided by the 17 foot long un-perforated 
(Super XX Panchromatic) 70 mm. roll film with fifty exposures. Loading is 
accomplished by placing the roll of film in the camera housing at the top; the 
film is automatically drawn into the camera by its electrically operated mech- 
anism. 
A photograph is taken by merely pressing the operating button on the rear 
of the camera. This trips the shutter and sets off the flash lamps simultaneously. 
The camera mechanism then automatically draws the exposed film into the 
magazine, and fresh film is drawn into position. 
The complete roll of film need not be used before removing the exposed film 
from the camera. The magazine containing the exposed film may be removed at 
any time by pressing the magazine release which automatically cuts the film, 
leaving the unexposed portion of the roll in the camera for future use. 
(2) Lighting.—This is provided by two or more Kodatron Speed-lamps 
synchronized with the camera. 
(3) Mirrors.—The eight mirrors are optically flat within three thousandths 
of an inch tolerance and are rigidly mounted in heavy metal frames, which are 
securely positioned.
