インダ。(1) The photographic light flux that has passed through the photographic lens is reflected and refracted by a reflector in the photographic optical path and guided to the finder device, and the image erected by the optical system in the finder device is observed through the eyepiece. In the finder device of a single-lens reflex camera, a triangular prism or a reflector is provided that reflects and refracts the light beam reflected by the photographing optical path reflector substantially parallel to the photographing light beam, and a triangular prism or a reflector disposed in front of or (and) after the triangular prism or reflector. A finder for a single-lens reflex camera characterized by this feature, comprising a condenser lens arranged in the front and an image reversing prism arranged after the triangular prism or the reflecting mirror.
