ABSTRACT:
A camera system rendering it possible to display stroboscopic information (for example, flash light information, electrical energy storage finish information and computer information) of a stroboscope in the interior of the finder of a single lens reflex camera. One of the features of the present invention is that the stroboscopic unit is provided with a stroboscopic information exit window in one side surface of the casing thereof, and the pentaprism housing of the camera is provided with a stroboscopic information entrance window in the opposite side surface thereof in alignment with the exit window so that the stroboscopic information is routed into the finder. Another feature is to provide a blind for light-shielding the entrance window so that when the stroboscopic unit is not in use and the entrance window is shut, the finder optical system is protected from the influence of ambient light in the daylight exposure mode.
