Zoom lens and image pickup apparatus having the same

A zoom lens comprising a plurality of lens units, the plurality of lens units consisting of, in order from an object side to an image side:

• a first lens unit having a negative refractive power;
• and
• a second lens unit having a positive refractive power,
• wherein an interval between the first lens unit and the second lens unit changes during zooming,
• wherein the first lens unit includes two meniscus lenses each having a negative refractive power and a convex shape toward the object side,
• wherein the first lens unit further includes one biconcave lens and one biconvex lens,
• wherein at least one of the two meniscus lenses includes an aspherical surface having a positive aspherical amount,
• wherein the second lens unit consists of a first subunit, a second subunit, and a third subunit in order from the object side to the image side,
• wherein the second subunit consists of a first cemented lens of a negative lens and a positive lens in order from the object side to the image side and a second cemented lens of a negative lens and a positive lens in order from the object side to the image side, and
• wherein the third subunit consists of a negative lens, a positive lens, and a positive lens in order from the object side to the image side.
