1. A lens barrel comprising:
a lens drive unit that moves a lens holder holding a lens in an optical axis direction;
a locking mechanism that regulates movement of the lens holder at a movable end of the lens holder; and
a control unit that performs, as a shift process for shifting the lens holder to a movement regulated state produced by the locking mechanism, control for moving the lens holder by using the lens drive unit to a position where movement regulation is achieved by the locking mechanism in a state where movement regulating force generated by the locking mechanism is reduced or eliminated.
