Abstract

A lens device includes: a lens that is movable in an optical axis direction; a rotating member that rotates in conjunction with movement of the lens in the optical axis direction; a first signal detection section that detects a signal which changes in accordance with a position of the lens in the optical axis direction; a second signal detection section that detects a signal which changes in accordance with an amount of rotation of the rotating member; a first lens position detection section that detects the position of the lens based on the signal detected by the first signal detection section; a second lens position detection section that detects the position of the lens based on the signal detected by the second signal detection section; and a control section as defined herein.
