Abstract

956,955. Cine cameras; exposure control. EASTMAN KODAK CO. Dec. 12, 1962 [Dec. 15, 1961], No. 46998/62. Headings G2A and G2E. The reflex view finder of a cine camera, having an objective 1 of variable focal length and a prism 2 for deflecting part of the light into the view finder, has an objective 4 forming a real image at 6, inverting lenses 7 and 8 and an eyepiece system 10, 11 and 12. Between lenses 7, 8 is an inclined reflector 14 directing part of the light through focusing lens 16 on to a photoresistance 17 of an exposure control device. Film sensitivity control is provided by a rotary disc 18, having a density which progresses in steps or continuously, or by a diaphragm and diffusing member, or by a grey wedge. Reflector 14 may be concave, in which case lens 16 may be omitted.
