Abstract: In an electrical exposure control device for use with reflex type photographic cameras, the voltage stored in a storage device is accurately retained after the light has been detected by a light receptive element and prior to the use of the stored voltage for purposes of exposure control by structure which ensures that the required switching of the stored voltage is coincidentally timed with the actual movement of the shutter mechanism to initiate an exposure, thereby eliminating unwanted decay between operation of a change-over switch and actual movement of the shutter mechanism.
