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, and a third lens unit having a negative refractive power. Each distance between two adjacent lens units varies during at least one of zooming and focusing. The first lens unit and the second lens unit move during zooming so that a distance between the first lens unit and the second lens unit at a telephoto end is shorter than that at a wide-angle end. The third lens unit moves during the focusing. Each lens unit includes at least one positive lens and at least one negative lens. Predetermined conditions are satisfied. |
