In a camera adapted to be sealed against water, a camera having a reciprocating lens barrel, a member for detecting water around the camera, and for controlling the lens barrel, so that the lens barrel will not be moved when water is detected by the detecting member. In another embodiment the camera is provided with a member for detecting water at a certain hydraulic pressure and a member for indicating an alarm when water at such a pressure is detected. Thus, by immobilizing the lens barrel, it is possible to prevent water damage to the camera that might result if the camera were submerged and the lens barrel moved.
