検出装置。The optical axis of one of the two distance-measuring optical systems with a baseline length is placed within the main imaging optical system that forms an image of the subject, and the optical axis of the other distance-measuring optical system is placed within the main imaging optical system that forms an image of the subject. In a focus detection device placed outside the system, the optical axis of one distance-measuring optical system placed inside the main imaging optical system is aligned with the optical axis of the other distance-measuring optical system. A plane that is decentered in a direction away from the optical axis of the system and includes the optical axis of one ranging optical system and the optical axis of the main imaging optical system, and the optical axis of the other ranging optical system and the main imaging system. A focus detection device characterized in that a plane containing an optical axis of an optical system is a different plane.
