Abstract
A lens barrel comprises an optical system provided within a main body of the barrel, an operation ring used for a photographer to operate the optical system, driving means, used for an electric drive, for generating a driving force transferred to the operation ring via a driving force transfer member, and a rotation restricting stopper for restricting a range of rotation of the operation ring. The rotation restricting stopper is movable between a position for restricting the range of the rotation of the operation ring and a position where the range of the rotation is not restricted, and substantially simultaneously restricts a range of rotation of the driving force transfer member in the position for restricting the range of the rotation of the operation ring.
