Abstract:
1. A zoom lens consisting of, in order from an object side to an image side: a first lens unit having negative refractive power; a second lens unit having positive refractive power; and a third lens unit having negative refractive power, wherein the first lens unit and the second lens unit move during zooming to make a distance between the first lens unit and the second lens unit smaller at a telephoto end than at a wide-angle end, wherein the third lens unit consists of, in order from the object side to the image side, a first lens subunit having positive refractive power and a second lens subunit having negative refractive power, and wherein the first lens subunit is fixed during focusing, and wherein the second lens subunit moves toward the image side during focusing from an infinite-distance object to a near-distance object.
