A single lens relfex camera is provided with a mirror which has a viewing position, where the mirror is inclined downwardly across an optical axis of a camera objective for directing an image of an object which is to be photographed upwardly to a viewfinder of the camera, and an exposure position, where the mirror is situated above the optical axis in a plane substantially parallel thereto. The mirror has in its viewing position a lower front edge situated beneath the optical axis and an upper rear edge situated above the optical axis rearwardly of the front edge. A structure is operatively connected with the mirror for moving the latter between its viewing and exposure positions, this structure when displacing the mirror from its viewing to its exposure position first retracting the mirror rearwardly while turning the mirror in an angluar direction and then turning the mirror in the opposite angular direction upwardly to its exposure position while when displacing the mirror from its exposure position to its viewing position the structure first turns the mirror and then displaces the mirror forwardly to its viewing position. |
