。A focus detection light receiving element is disposed at a position substantially conjugate to the film surface, and a distance measuring optical system is provided on the main movable mirror of the camera to form at least a part of the subject image on the light receiving element through the photographing lens. In a single-lens reflex camera equipped with a sub-movable mirror that guides a light flux that passes through one half of the mirror to the light-receiving element, a space surrounded by the main movable mirror, the sub-movable mirror, and the focus detection light-receiving element; In conjunction with the rotation of the main movable mirror, when observing a subject, light is blocked to prevent reverse light from the finder and light from the gap between the bottom of the mirror box and the main movable mirror from entering the focus detection light receiving element. A light shielding device for a single-lens reflex camera, further comprising a light shielding member that closes the semi-transparent part during exposure.
