Patent ID: 7154682

Claim:
An optical apparatus comprising: a light-quantity-adjusting unit; a first lens unit disposed closer to an object than the light-quantity-adjusting unit; a second lens unit disposed closer to an image plane than the light-quantity-adjusting unit; a holding member holding the first lens unit and the second lens unit; a drive unit driving the holding member in a first orthogonal-to-the optical-axis direction; and the holding member including: a first holder holding the first lens unit; a second holder holding the second lens unit; a connector connecting the first holder and the second holder along a second orthogonal-to-an optical-axis direction, and the light-quantity-adjusting unit being inserted and disposed into a space defined by the first holder, the second holder, and the connector, from a third orthogonal-to-an-optical-axis direction that is orthogonal to the second orthogonal-to-an-optical-axis direction.
