A zoom lens including a plurality of lens groups and varying magnification by changing a distance between lens groups, wherein a last lens group positioned on an image side closest thereto with a negative part group having negative refractive power and a positive part group arranged adjacent on the image side thereof and having positive refractive power, wherein the positive part group is shifted in a direction vertical to an optical axis to shift an image, and Equations (1) and (2) are satisfied, −0.30 30  (2) where, fgn: focal length of the negative part group, Ngn: average refractive index of the negative part group, fT: focal length of the entire system at a telephoto end, νgn: composite Abbe number of the negative part group, and νgis: composite Abbe number of the positive part group.
