Abstract
A camera having an electrically operated self-timer is provided with an operation mode display device arranged so that when the camera is switched to an exposure control mode by the self-timer, the display being ready for actuation of the timer is rendered recognizable from the object side or to the photographer, while when switched to any other exposure control mode, this display is shielded so as not to be recognizable from the object side or to the photographer.
