Abstract

To obtain a zoom lens which is small in entire size, has a high zoom ratio, corrects aberration variation well in image blurring correction, and achieves high optical performance in the image blurring correction, 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 first subunit with a positive refractive power, a second subunit with a positive refractive power which moves in a direction having a component of the direction perpendicular to the optical axis, and a third subunit with a negative refractive power. A focal length of the zoom lens when focused at infinity at a wide angle end fw and a focal length of the correction lens unit fxyz are appropriately set.
