ABSTRACT:
A super wide-angle zoom lens includes at least a negative first lens group and a positive second lens group, in this order from an object side. A zooming operation is carried out by relatively moving the lens groups. When a photographing area is defined by a rectangular area, a boundary of a circular image forming area formed by the zoom lens is at least partially disposed in the rectangular photographing area at the shortest focal length of the zoom lens.
