Abstract

A camera is provided with a multi-exposure control system for obtaining proper exposure by either preselecting the diaphragm or the shutter speed and then respectively automatically controlling the shutter speed or the diaphragm aperture in accordance with the intensity of scene light passing through the diaphragm aperture. Structure is provided for obtaining a proper exposure by causing the diaphragm to be either fully opened or at its smallest aperture where with a preselected shutter speed an intermediate diaphragm aperture is not satisfactory. The exposure indicating device obtains an output voltage from an output circuit for computing exposure control voltages in response to step members representing steps of the diaphragm for stopping-down the diaphragm from its fully opened condition to a preselected value so that the output represents the shutter speed to be controlled with the preselected diaphragm aperture.
