Abstract
A viewfinder system of a photographic or cinematographic camera, provided with a varifocal objective, is illuminated by light deviators including a fully reflective mirror intercepting part of the light rays passing from the fourth to the final component of the objective. The mirror has a body of dark-stained glass, designed to prevent spurious reflections at the edges, and is coated on its front surface with a reflective layer produced by vapor deposition.
