    摘要： The present invention is directed to a compact and lightweight high magnification zoom lens utilizing a 4-element zoom layout of positive, negative, positive, and positive in refractive property, which is approximately 75 degrees in shooting angle of view at a wide-angle end, approximately F/3 to F/4 in F-number at the wide end, approximately F/5 to F/6 at a tele end, and approximately 6 to 7 in zoom ratio. The zoom lens includes first to fourth elements each comprised of a plurality of lenses, and the elements have respective refractive powers of positive, negative, positive, and positive levels in order from the closest to a subject. Only the second element of lenses is moved for focusing while the conditions described as follows are satisfied: 0.065
