摘要： A zoom lens includes, in order from the object side to the image side, a positive refractive first lens unit, a negative refractive second lens unit, a positive refractive third lens unit, and a rear group including one or more lens units. The first lens unit consists of a negative lens and a positive lens. The first to third lens units and the lens units constituting the rear group move at a time of zooming. The first and third lens units move relative to the image plane in such a way that their respective positions at the telephoto end are displaced toward the object side from their respective positions at the wide angle end. The focal lengths f1, f2 of the first and second lens units and the focal lengths fw, ft of the whole system at the wide angle end and at the telephoto end are arranged appropriately.
