A lens barrel which includes an optical system, a support mechanism, a drive correcting mechanism, a retractable lens frame, and a drive retracting mechanism. The optical system includes a corrective lens group and a retractable lens group. The support mechanism movably supports the corrective lens group in a direction perpendicular to the optical axis of the optical system. The drive correcting mechanism is configured to drives the support mechanism so that the corrective lens group moves in a direction perpendicular to the optical axis of the optical system. The retractable lens frame retractably supports the retractable lens group to a first position in which the optical axis of the retractable lens group is offset from the optical axis of the optical system. The drive retracting mechanism is configured to drive the retractable lens frame so that the retractable lens group retracts to the first position. |
