Abstract

A zoom lens consists of, in order from an object side to an image side, a first lens unit having a positive refractive power, a second lens unit having a negative refractive power, a third lens unit having a positive refractive power, and a rear unit that includes a plurality of lens units. All lens units move during zooming, and a distance between adjacent lens units changes. The third lens unit includes, in order from the object side to the image side, a first subunit having a positive refractive power, a second subunit having a positive refractive power, and a third subunit having a positive refractive power. The second subunit includes a negative lens and a positive lens. The second subunit moves in a direction having a component orthogonal to an optical axis during an image stabilization. A predetermined condition is satisfied.
