PROBLEM TO BE SOLVED: To provide a lens device and an optical device that can easily correct an optical performance of an optical system according to a predetermined parameter for changing the optical performance of the optical system, on the premise of a change in clearance of a holding mechanism holding a lens.SOLUTION: A lens device includes: an optical system that has a lens displaceable in a displacement direction different from an optical axis; a holding that holds the lens; and driving means that drives the lens in the displacement direction. The lens device comprises: detection means that detects a parameter changing an optical performance of the optical system; and storage means that stores an amount of drive correction according to the parameter of the optical system. The driving means is configured to drive the lens using the amount of drive correction according to a detection result of the detection means and stored in the storage means. |
