A zoom lens includes, in order from an object side to an image side, first to fourth lens units having negative, positive, negative, and positive refractive power, respectively. During zooming from a wide-angle end to a telephoto end, at least the first, second, and third lens units move. The focal lengths of the first, second, and third lens units, the amount of movement of the second lens unit during zooming from the wide-angle end to the telephoto end, a lateral magnification at the wide-angle end of the second lens unit, a lateral magnification at the wide-angle end of the third lens unit, a lateral magnification at the telephoto end of the second lens unit, and the lateral magnification at the telephoto end of the third lens unit are appropriately set. |
