Abstract
A zoom lens comprising, in order from an object side to an image side, a first lens unit having a positive refractive power, a second lens unit having a negative refractive power, a third lens unit having a positive refractive power, and a fourth lens unit having a positive refractive power an interval between adjacent lens units changing and the first to fourth lens units moving during zooming. An image blur is corrected by moving a sub-unit having a negative refractive power as a whole in the third lens unit orthogonally to an optical axis. A predetermined conditions are satisfied.
