。 A first mirror whose part or entire surface is a collection of semi-transparent or total transmission and total reflection guides the light from the subject that enters from the photographing optical system to the finder optical system, and the incident light is directed to a light-receiving element used for distance measurement. In a single-lens reflex camera having a second mirror that guides a part of the mirror, a support member that can rotate integrally with the mirror frame of the first mirror is provided, and a second mirror support arm is attached to a bearing portion of the support member. a reference contact portion that pivots an intermediate portion of the support member and abuts one end of the second mirror support arm against the support member with a spring bias to position the second mirror attached to the second mirror support arm at a photometry position; and a second mirror actuating cam is disposed, the mirror actuating cam engaging portion at the other end of the second mirror supporting arm engages when the first mirror is actuated to swing the second mirror supporting arm. A mirror actuator in a single-lens reflex camera.
