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.
Claims2
A lens barrel comprising:
- an optical system provided within a main body of said barrel;
- an operation ring used for a photographer to operate said optical system;
- driving means, used for an electric drive, for generating a driving force transferred to said operation ring via a driving force transfer member;
- and
- a rotation restricting stopper for restricting a range of rotation of said operation ring,
- wherein said rotation restricting stopper is movable between a position for restricting the range of the rotation of said operation ring and a position where the range of the rotation is not restricted, and substantially simultaneously restricts a range of rotation of said driving force transfer member in the position for restricting the range of the rotation of said operation ring.
