Abstract: Coincidence of the fields of view of the photocell and film is important in automatically exposure-controlled cameras for certain types of scenes. The sensitivity of selenium photocells makes this difficult to achieve. The use of different focal length lenses and zoom-type lenses can aggravate the problem seriously. An 8mm zoom motion-picture camera is discussed which provides a solution to this problem.
