The camera of the invention has a clean and semi-external electric source. In the camera, an electric section includes a photometric circuit and a display unit. A solar cell is the electric source. A capacitor is charged by the solar electric power. A release switch is linked with a shutter release button. The release switch connects the solar cell and the capacitor and disconnects the solar cell and the capacitor when the shutter release button is half pushed. The release switch drives a shutter when the shutter release button is fully pushed. A selecting switch is connected to the release switch. The selecting switch has a first position, at which the solar cell and an electric section are connected and the capacitor and the electric section are disconnected, and a second position, at which the solar cell and the electric section are disconnected and the capacitor and the electric section are connected.
