ことを特徴とする自動焦点カメラ。In an autofocus camera that adjusts the focus state of the photographic lens by detecting infrared light from the light emitting element reflected by the subject with the light receiving element, a portion of the photographing light from the photographing lens is used. An infrared light reflecting surface is formed in a half prism with a semi-transmissive surface for guiding the light to the finder optical system in a direction different from the semi-transmissive surface, so that the infrared light from the light projecting element is directed to the photographic lens. An autofocus camera that is characterized by the ability to pass through the interior.
