A zoom lens comprising, in the order from the object side, a front lens group including a variator lens unit with a negative refractive power; an aperture stop; and a rear lens group arranged behind the aperture stop. The rear lens group includes a lens unit having a positive refractive power, a focusing lens unit having a negative refractive power, and a compensator lens unit having a positive refractive power. At the time of zooming, the lens unit having the positive refractive power moves together with the focusing lens unit, and at the time of focusing, only the focusing lens unit moves separately from the lens unit having the positive refractive power.
