レツクスカメラのフアインダ装置。 A photographing lens that forms an image of a subject while standing upright and with its left and right sides rotated in the right direction, an optical path switching mirror that switches the emitted light of the photographic lens between a position where it guides it to the film surface and a position where it guides it to the viewfinder side, and this optical path switching mirror. In a single-lens reflex camera, the single-lens reflex camera has a finer screen located behind the optical path when the lens is positioned to guide the light emitted from the photographing lens toward the finer lens. A mirror is provided that is movable between a first position approaching the image formed on the screen and a second position where the optical path is bent and guided to the eyepiece when the optical path switching mirror is at a position where the optical path is guided to the viewfinder side. A finder device for a single-lens reflex camera characterized by:
