Abstract
A lens device includes a first lens system including a first lens, a second lens system including a second lens, a moving member configured to move in an optical axis direction of the first lens, and a physical structure configured to move the first lens in the optical axis direction and move the moving member in a direction opposite to a movement direction of a center of gravity of a physical system that includes the first lens.
Claims20
A lens device comprising:
- a first lens system including a first lens;
- a second lens system including a second lens;
- and
- a cam ring configured to move the first lens in an optical axis direction of the first lens, wherein the cam ring moves in a direction opposite to a movement direction of a center of gravity of the lens device according to a movement of the first lens.
