Original Abstract Submitted

a zoom lens comprises a first lens unit having a positive refractive power, a second lens unit having a negative refractive power, a third lens unit having a positive refractive power, and a subsequent group including three or more lens units, arranged in this order from an object side toward an image side, wherein in zooming from a wide angle end toward a telephoto end, the first lens unit, the third lens unit and all the lens units of the subsequent group move toward the object side, and the second lens unit moves in a trajectory that is convex toward the image side, and wherein predetermined inequalities are satisfied.
