Abstract
An optical apparatus includes a lens barrel, an optical apparatus body, a body-side mounting unit, a lens-side mounting unit and a position determination mechanism. A plurality of projection pins protrude from an outer circumferential surface of a cylindrical part of the body-side mounting unit. A groove is formed in an inner circumferential surface of the lens-side mounting unit. Cutout regions that are in communication with the groove are formed in a surface of the lens-side mounting unit that faces toward a flange part of the body-side mounting unit at positions that respectively correspond to positions of the projection pins. The position determination mechanism determines a position of the lens-side mounting unit around the optical axis of the optical apparatus body.
