ABSTRACT:
A super wide angle zoom lens includes a first lens group of negative power and a rear lens group of positive power, in this order from the object side, so that zooming may be carried out by relatively moving the first lens group and the rear lens group. The zoom lens has, at a wide angle extremity thereof, a half angle of view of more than 60.degree., which constitutes a half angle of view of a fisheye lens.
