A zoom lens includes, in order from an object side to an image side, a first lens unit having a negative refractive power, a second lens unit having a positive refractive power, a third lens unit having a negative refractive power, a fourth lens unit having a positive or negative refractive power, and a fifth lens unit having a positive refractive power. In the zoom lens, the first lens unit is stationary during zooming. At least the second lens unit, the third lens unit, and the fifth lens unit move along an optical axis during zooming. Furthermore, in the zoom lens, a focal length of the entire zoom lens at a wide-angle end (fw) and an amount of movement of the second lens unit during zooming from the wide-angle end to a telephoto end (m2z) are appropriately set.
