Abstract: An image capturing apparatus is provided to allow a user to check an image of a subject with his naked eyes in a bright state by using an optical finder without additionally installing a movable reflection mirror about an optical path. As a reflection angle of a reflective surface(65e) of a finder optical system is changed, a course of an optical flux for observation is converted between an optical path(PA) along which the optical flux is directed toward a finder window after being reflected from the reflective surface and an optical path(PB) along which the optical flux is directed to an image capturing element(7) after being reflected from the reflective surface. If the course of the optical flux for observation corresponds to the optical path, lateral light is processed by using the image capturing element disposed at the optical path after the proceeding direction of the optical flux is changed by a beam splitter(71) disposed at the optical path. If the path of the optical flux for observation corresponds to the optical path, lateral light is processed by using a lateral light sensor(79) disposed near the optical path.
