摘要： A zoom lens comprises in order from an object 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, and a fourth lens unit having a negative refractive power. The second lens unit comprises in order from the object side, a positive lens, a negative lens, and a positive lens. At the time of zooming from a wide angle end to a telephoto end, the first lens unit moves toward the object side, and the fourth lens unit moves, and a distance between the first lens unit and the second lens unit decreases monotonically, a distance between the second lens unit and the third lens unit increases monotonically, and a distance between the third lens unit and the fourth lens unit increases monotonically.

摘要： A zoom lens comprises in order from an object side, a first lens unit, a second lens unit, a third lens unit, a fourth lens unit, and a fifth lens unit having, respectively, a positive, negative, positive, negative, and positive refractive power. At the time of zooming from a wide angle end to a telephoto end, the first, third, and fourth lens units move toward the object side. A distance between the first and second lens units increase, a distance between the second and third lens units decrease, a distance between the third lens unit and the fourth lens unit changes, and a distance between the fourth lens unit and the fifth lens unit increases. The zoom lens satisfies the following expressions: 1.54
