A photographic camera having an interchangeable lens and an automatic exposure control and focusing device comprising a computing circuit for the determination of the front and rear depth-of-field planes. The computing circuit is connected to a data memory on the camera side, a control unit, an autofocus central unit and an exposure control device. At a given stored sharpness and open aperture, the front and rear depth-of-field planes are automatically controlled by means of a setting element and can be assessed in the viewfinder. A predetermined depth-of-field range can be set and the required aperture can be displayed in the viewfinder and set, if this aperture is present on the interchangeable lens. The controlled depth-of-field planes remain visible in the viewfinder for a predetermined period of time.
