During zooming from the wide angle end to the telephoto end, the distance between the first lens unit and the second lens unit decreases, the distance between the second lens unit and the third lens unit changes. The first lens unit includes, in order from the object side, a first lens element, which is a negative lens element, and a second lens element, which is a positive lens element. The negative lens element and the positive lens element satisfy specific conditions.
