Abstract
A lens barrel that achieves modes with and without an optical element while reducing a size in an optical axis direction. A first drive mechanism moves a first optical element in the optical axis direction. A second optical element is located at an image surface side of the first optical element and is selectively inserted in an optical path. A second drive mechanism moves a holding member that holds the second optical element in a direction different from an optical axis. A control unit controls the first drive mechanism to move the first optical element to an object side to a position where the first optical element and the holding member are not in an overlap state when viewing in a direction perpendicular to the optical axis, controls the second drive mechanism to remove the second optical element from the optical path, when they are in the overlap state.
