A lens cap is formed with not only a lens covering portion for covering the photographic objective lens of a camera, but also with both a portion, such as protection wall for preventing inadvertent operation of the camera shutter release button and a projection for preventing unexpected movement of the operation member of the camera which is adapted for switching the camera from a normal photography condition to a flash photography condition. The lens cap may be further provided with covering portion for covering the camera viewfinder window as well as the range finder window.
