At the time of zooming, the third lens unit G3 moves in a direction along the optical axis such that an interval between the second lens unit G2 and the third lens unit G3 is made longer at a telephoto limit than the interval at a wide-angle limit. Further, at the time of focusing, the third lens unit G3 moves in the direction along the optical axis such that the interval between the second lens unit G2 and the third lens unit G3 varies.
