Abstract
PURPOSE:To perform the swtiching of finders, by using a reflector which can be freely put in and taken out an optical path of an optical finder system. CONSTITUTION:One of the beams passed through a photographing lens 11 is led to an image pickup tube 23 by an optical divider 12, and the other beam is led to an eyepiece 19 by an optical finder system, i.e., a reflector 14. A reflector 20 which is freely attached and detached is provided to the optical path of the optical finder system. At the position shown in the diagram, the image of an electronic finder CPT21 can be observed through the eyepieces 19. The subject image can be observed directly through the eyepiece 19 and via the optical finder system by detaching the reflector 20 out of the optical path of the optical finder system.
