Abstract
In a dual lens camera having a relatively long focal length lens and a relatively short focal length lens selectively used for telephoto and wide angle photography, the lens selection is controlled by movement of a movable mirror with respect to a fixed mirror to establish respective optical pahts for the two lenses. Whenever a back cover of the camera is opened for film loading or unloading, the movable mirror is secured to affix its reflective surface in shielding relation with the reflective surface of the fixed mirror. This is done to prevent dust or other foreign particles entering the surfaces, and to render the reflective surfaces inaccessible to touch.
