Abstract:
A zoom lens comprising, in order from an object side,a first lens unit of positive refractive power; a second lens unit of negative refractive power; a third lens unit of positive refractive power; a fourth lens unit of negative refractive power, wherein said fourth lens unit comprises two or more lens components including a lens component of negative refractive power; and a fifth lens unit of positive refractive power, wherein predetermined lens units move during zooming from a wide-angle end to a telephoto end so that a separation between said first and second lens units increases, a separation between said second and third lens unit decreases, a separation between said third and fourth lens units increases, and a separation between said fourth and fifth lens unit decreases, and wherein an image is displaced by moving the lens component of negative refractive power in said fourth lens unit so as to have a component of a direction perpendicular to an optical axis of said zoom lens, and wherein a condition 0.01
