ABSTRACT:
A self-adjusting electronic flash is attached to an interchangeable lens camera having a shutter-priority exposure control. For flash operation, aperture information suitable for electronic flash and the film sensitivity is automatically conveyed to the camera's diaphragm control. Thus the aperture can be automatically adjusted for flash as well as daylight operation.
