Abstract
A zoom lens according to the present invention includes, in order from an object side to an image side, first to third lens units with positive, negative and positive refractive powers, and a rear group including two or more lens units, in which an interval between adjacent lens units is varied during zooming. The zoom lens includes a correction lens unit which has a function of moving an imaging position in a direction perpendicular to an optical axis. The correction lens unit includes, in order from the object side to the image side, a positive first subunit, a positive second subunit which moves in a direction having a component of the direction perpendicular to the optical axis, and a negative third subunit. Focal lengths of the zoom lens when focused at infinity at a wide angle end and the correction lens unit are appropriately set.
