A zoom lens includes, in order from an object side to an image side: a first lens unit having positive refractive power, which does not move for zooming, the first lens unit including a lens unit which moves for focusing; a second lens unit having negative refractive power for magnification variation; a third lens unit having negative refractive power, which moves for zooming; a fourth lens unit having positive refractive power, which moves for zooming; and a fifth lens unit having positive refractive power, which does not move for zooming, in which an interval between the fourth lens unit and the fifth lens unit becomes largest at a telephoto end, and lateral magnifications ²2w and ²2t of the second lens unit at a wide-angle end and at the telephoto end are respectively set appropriately.
