ABSTRACT:
An auto-focus camera comprising a rangefinder system, an automatic focus adjusting system, a manipulatable zone selector mechanism and a selector switch for electrically connecting the automatic focus adjusting system selectively to the rangefinder system and to the manipulatable zone selector mechanism depending upon the position of the selector switch. In one operative mode, an automatic focus control signal indicative of the zonal distance of the target object to be photographed to the camera and generated from the rangefinder system is applied to the automatic focus adjusting system to bring an objective lens assembly to one of focal positions determined by the automatic focus control signal. In another operative mode, a manual focus control signal indicative of a desired one of the focal positions of the objective lens assembly is applied to the automatic focus adjusting system to bring an objective lens assembly to the desired focal position.
