ABSTRACT:
A zoom lens system has, from the object side, a first lens unit, a second lens unit with an aperture stop, and a third lens unit. In this zoom lens system, zooming is performed by varying the distances between these lens units; focusing from the infinite distance to the closest distance is performed by moving the first lens unit toward the object side along the optical axis; image blur compensation is performed by decentering an image blur compensating lens unit included in the third lens unit.
