A photographic camera with automatic setting of diaphragm and exposure time. A light sensitive circuit generates pulses and is connected to a diaphragm counting stage for comparing signals from the light sensitive circuit with preset signals in the diaphragm counting stage and for providing a stop pulse to an electromagnetic diaphragm setting stage. A counter is connected to a pulse generator and to the diaphragm counting stage in a stop control connection. A start control provision connects the output of the diaphragm counting stage to an exposure time forming stage. The exposure time forming stage can be connected to the counter for providing automatic setting of the time determining part of the exposure time forming stage depending on the counting state of the counter. A shutter opening member can be connected to the diaphragm counting stage for receiving a control signal for the release part of the shutter opening member.
