Claim:
A lens barrel comprising: a first focus ring, which is a focus ring rotatably arranged on an outer circumference portion of a barrel body holding an optical system capable of focus control and used for either one of instruction types of focus operation of a relative position instruction type focus operation for moving a position of the focus lens for focus control with respect to an optical axis direction in a relative positional relation to a rotation position of the focus ring and an absolute position instruction type focus operation for moving it in an absolute positional relation; a second focus ring, which is a focus ring arranged rotatably on the outer circumference portion of the barrel body holding the optical system capable of focus control and used for the focus operation of the instruction type different from that of the first focus ring between the relative position instruction type focus operation and the absolute position instruction type focus operation; a support device which slidably supports the first focus ring in the optical axis direction; a connecting device which brings the first focus ring and the second focus ring from an unconnected state into a connected state when the first focus ring slidably supported by the support device is slid from a first position to a second position; and a cover member covering the outer circumference portion of the second focus ring.
