A zoom lens is composed, in order from the object side thereof, of a front side lens unit having a negative refracting power at the wide angle end and a rear side lens unit having a positive refracting power at the wide angle end. The front side lens unit includes a first lens unit located closest to the object side and having a positive refracting power and a second lens unit located on the image side of the first lens unit and having a negative refracting power. The distance between the first lens unit and the second lens unit is larger at the telephoto end than at the wide angle end. The rear side lens unit includes a third lens unit located closer to the object side at the telephoto end than at the wide angle end and having a positive refracting power, the distance between the third lens unit and the second lens unit being smaller at the telephoto end than at the wide angle end. The third lens unit satisfies the following condition: 0.01<f3/ft<0.16 . . . (1).
