Abstract: In the disclosed electronic flash, camera operation at various depths of field is made possible by producing a diaphragm-setting signal in response to a preliminary flash directed at a preliminary object, converting this signal to a digital value, and adjusting the main flash in response to light reflected from a main object and in response to the digitally memorized diaphragm setting signal.

Abstract: A flash system including a computer type electronic flash unit and a camera. The computer type electronic flash unit includes an output terminal at which a signal representing the fully charged condition of an electrical energy storage capacitor is produced, a firing stop signal generating circuit and a signal supply circuit for supplying the output of the generating circuit to the output terminal. The camera includes an indicating device connected to the output terminal for indicating the firing stop signal transmitted from the output terminal. The camera also includes an override circuit for inhibiting the charge completion signal from being transmitted to the indicating means in response to a release operation of the camera.

Abstract: PROBLEM TO BE SOLVED: To provide a camera which is never broken even when a small-sized transistor, etc., is used as a switch element. SOLUTION: The camera has a synchro terminal for an externally connected flash unit, a semiconductor switch element for synchronism which is connected to the synchro terminal, and a decision circuit which decides the voltage at the synchro terminal prior to shutter operation and when the decision circuit judges that the voltage at the synchro terminal is higher than a specified value, the semiconductor switch element is inhibited from operating.

Abstract: PROBLEM TO BE SOLVED: To solve the problem that there is a possibility that a mechanical switch is damaged because a heavy-current is caused to flow when a semiconductor switch for synchronization is turned on if an electronic flash having a high voltage synchronization circuit is connected to the mechanical switch. SOLUTION: A camera to which a lighting system for emitting illuminating light can be attached is provided with: a first semiconductor switch element 38 which has a current retention characteristic and is turned on in response to a synchronization signal for making the lighting system emit light to make the lighting system emit light; a second semiconductor switch element 40 which is connected in parallel to the first semiconductor switch element, whose voltage when turned on is lower than the terminal voltage of the first semiconductor switch element when turned on and which does not have a current retention characteristic; and a controlling means 30 for turning on the second semiconductor switch element and subsequently turning off the second semiconductor switch element according to the lapse of time after the first semiconductor switch element is turned on.
