Abstract
When focal lengths are discretely set, zoom positions are set, relative to a focal length fr at a position at which a movement direction of a correction group, is reversed, such that a difference value between a focal length which is the closest to the focal length fr and falling between a focal length fw at a wide angle end and the focal length fr, and a next focal length is larger than a difference value between any remaining adjacent focal lengths. By moving from the zoom position of the closest focal length directly to the zoom position of the next focal length, a movement range of the correction group can be made smaller than a movement range in the case where the lens position of the focal length fr is set as the zoom position.
