<p>PROBLEM TO BE SOLVED: To shorten an entire length in a contraction state in lens barrels contractable and including a lens shift actuator.SOLUTION: A lens barrel including a lens shift actuator for a tremor correction comprises: a first lens drive part that drives a shift lens group hold frame holding a shift lens group and the lens shift actuator; and a second lens drive part that drives the lens group located on an image side of the shift lens group hold frame. When viewing in a direction along an optical axis, the second lens drive part is disposed at a position which is inside the shift lens group holding frame and does not overlap with the lens shift actuator.</p> |
