ABSTRACT:
A zoom lens system has at least three lens units. A first lens unit situated at an object side of the zoom lens system has a positive optical power. Zooming is performed by varying distances among the lens units. A camera shake compensating lens unit, including at least one positive lens element and at least one negative lens element, is provided in the first lens unit. The camera shake compensating lens unit is parallelly decentered to perform camera shake compensation. The ratio of the focal length f of the zoom lens system to the composite lateral magnification (.beta.r) of the lens units situated on the image side of the camera shake compensating lens unit fulfills a condition 30<f/.beta.r<120.
