ABSTRACT:
An automatic rangefinding camera uses a light source, such as an electronic flash, to direct light toward an object to be photographed. The quantity of such light reflected by the object to be photographed is converted into an electrical signal that can be translated by a converter into ranging information. Included on the camera is a switch which, when moved to the OFF position, disables the exposure flash and simultaneously moves a filter in front of the flash tube so that invisible radiation is used for auto-ranging. When lighting conditions are such that the exposure flash is required, movement of the switch to the ON position energizes the exposure flash and at the same time moves the filter out of the light path, thus uncovering the flash tube.
