In a camera in which the back cover is opened and closed to change the film, there are two positions: a closed position where the photographing optical path is blocked between the rearmost surface of the photographing lens in the camera dark box and the film gate including the film gate surface, and an open position where the photographic optical path is evacuated. and an opening for moving the lens protection member from the closed position to the open position between the closing of the back cover and the first frame setting of the film. and a closing drive means for moving the lens protection member from the open position to the closed position between the start of film rewinding and the opening of the back cover. A lens protection device for a camera, characterized in that a lens protection member is arranged to face the rearmost surface of the photographic lens to prevent fingers from touching the rearmost surface and dust from adhering to the photographic lens while the photographic lens is in use.
