摘要： A zoom optical system has, in order from the object side, a first lens unit with negative refracting power, including a single lens component; a second lens unit with positive refracting power, simply moved toward the object side when the magnification of the zoom optical system is changed in the range from a wide-angle position to a telephoto position; a third lens unit with negative refracting power; and a fourth lens unit with positive refracting power. In focusing on an object point separated at least 300 times a focal length at the wide-angle position, when the magnification is changed in the range from the wide-angle position to the telephoto position, the third lens unit and the fourth lens unit are moved together so that a relative spacing between the third lens unit and the fourth lens unit is widened or the fourth lens unit approaches an imaging point.
