Abstract
A zoom lens includes, in order from a magnified side to a minified side, a first lens group, an aperture stop, and a second lens group. The second lens group has at least one aspheric surface. The zoom lens satisfies the conditions: 0.1<Ic/TTLw<0.15 and TTLw/EFLw≤10, where Ic denotes a radius of an image circle, TTLw denotes a total track length of the zoom lens in the wide configuration, and EFLw denotes an effective focal length of the zoom lens in the wide configuration.
