Original Abstract Submitted

A zoom lens system includes multiple lens groups and an aperture stop. The multiple lens groups consist of: a first lens group having negative power; a second lens group having positive power, a third lens group having negative power; and a fourth lens group having negative power. The aperture stop is disposed between the first and second lens groups. The zoom lens system satisfies 0.5<fw/BFw <1.5, where fw is a focal length of the zoom lens system at a wide-angle end and BFw is a back focus of the zoom lens system at the wide-angle end.
