Abstract:
Provided is a zoom lens, including, in order from an object side to an image side: a negative first lens unit; a positive second lens unit; a negative third lens unit; a positive fourth lens unit; and a positive fifth lens unit, the first, second, third, fourth, and fifth lens units having an interval between each pair of adjacent lens units changed for zooming. The second, fourth, and fifth lens units are configured to move toward the object side for zooming from a wide-angle end to a telephoto end. A focal length of the fourth lens unit, a focal length of the fifth lens unit, an amount of movement of the fifth lens unit for zooming from the wide-angle end to the telephoto end, and a focal length of an entire system of the zoom lens at the wide-angle end are each appropriately set.

Claim (Index 1):
A zoom lens, comprising, in order from an object side to an image side:\n a first lens unit having a negative refractive power; a second lens unit having a positive refractive power; a third lens unit having a negative refractive power; a fourth lens unit having a positive refractive power; and a fifth lens unit having a positive refractive power,\n the first lens unit, the second lens unit, the third lens unit, the fourth lens unit, and the fifth lens unit having an interval between each pair of adjacent lens units changed for zooming, \n wherein the second lens unit, the fourth lens unit, and the fifth lens unit are configured to move toward the object side for zooming from a wide-angle end to a telephoto end, and wherein the following conditional expressions are satisfied:\n 0.01< f 5/ f 4<0.50; and \n 1.8<\u2212 M 5/ fw< 10.0, \n where f4 represents a focal length of the fourth lens unit, f5 represents a focal length of the fifth lens unit, M5 represents an amount of movement of the fifth lens unit for zooming from the wide-angle end to the telephoto end, and fw represents a focal length of the zoom lens at the wide-angle end, the amount of movement having a positive sign when a lens unit is positioned closer to the image side at the telephoto end than at the wide-angle end, and a negative sign when the lens unit is positioned closer to the object side at the telephoto end than at the wide-angle end.
