A zoom lens system includes a first lens group, a second lens group, a third lens group, a fourth lens group, and an aperture stop, from an object side to an image side on an optical axis. The zoom lens system satisfies the following condition: Y × L 2 × f W × f T ≤ 1.06 where Y is a maximum diagonal length of the image side 170, L is a total track length of the zoom lens system 100, fW is a focal length of the zoom lens system 100 at a wide status, fT is a focal length of the zoom lens system 100 at a telephoto status.
