<p>A camera and electronic flash combination is provided which permits the electrical circuits of a camera and an electronic flash to be coupled to each other through four terminals, thus achieving an efficient transfer of signal between both units. The electronic flash includes an illumination control circuit which can be controlled by an illumination control signal from the camera, preferentially from an output from a photometric circuit contained in the electronic flash, by an operation of a changeover switch which is disposed within the camera.</p> |
