Abstract
A zoom lens includes, in order from an object side to an image side, a first lens unit having positive refractive power, a second lens unit having negative refractive power, and a rear group having positive refractive power as a whole and including three or more lens units. During zooming, all lenses move and a distance between adjacent lens units changes. A lens unit closest to an image plane in the rear group moves toward the object side during zooming from a wide-angle end to a telephoto end. The first lens unit consists of, in order from the object side to the image side, one negative lens and two positive lenses. Predetermined inequalities are satisfied.
