しめるようにして成るカメラ装置。A camera device configured to cause light from a subject to enter a photosensitive surface via a lens system to form a subject image and also to be made to enter an optical viewing system, and further comprising a focus detection means, which is arranged in the lens system. was done,
a beam splitter that transmits most of the visible light and reflects a portion of the visible light and infrared light; and a beam splitter that transmits the infrared light and reflects the visible and infrared light, the beam splitter being disposed at a predetermined position relative to the beam splitter. a tychroic mirror; an infrared light source disposed at a predetermined position with respect to the tychroic mirror;
and a focus detector, which causes infrared light from the infrared light source to pass through the guichroic mirror, then be reflected by the beam splitter, and then pass through the lens system to illuminate the subject. , the reflected light is made to enter the focus detector to detect the focus, and the light from the subject is made to enter the beam splitter via the lens system, and the transmitted light is made to enter the photosensitive surface. The camera device is configured such that the reflected light is further reflected by the guichroic mirror and made to enter a viewfinder lens.
