A zoom lens easily performs image stabilization with a compact and light image-stabilizing lens unit, properly corrects an aberration change during image stabilization, and achieves high optical performance. The zoom lens includes a first positive lens unit, a second negative lens unit, a third positive lens unit, a fourth negative lens unit, and a fifth positive lens. These lens units are arranged in order from an object side toward an image side, and are moved during zooming. The fourth lens unit is formed by one lens component, and is moved in a direction having a component that is perpendicular to the optical axis for image shifting. The Abbe number of a negative lens that forms the fourth lens unit, the thickness of the fourth lens unit on the optical axis, and the focal length of the entire zoom lens at the wide angle end are set appropriately.
