A taking lens consists of first to third lens groups. The second lens group is held in a lens frame that is coupled through an arm to a supporting shaft, and is able to rotate about the supporting shaft, to move the second lens group in a circular direction in a plane perpendicular to an optical axis of the taking lens. As a movable lens barrel retreats into a camera body, the lens frame rotates to remove the second lens group from an inserted position inserted in an optical path of the taking lens to a removed position set out of the optical path. The arm is provided with an actuator that causes the lens frame to move in a lengthwise direction of the arm. Because the movement in the circular direction includes a component that is perpendicular to the lengthwise movement of the arm, it is possible to move the lens frame and thus the second lens group in any directions in the perpendicular plane to the optical axis, in order to cancel a deviation of an optical image that result from a camera shake. |
