Abstract: A super wide angle zoom lens comprises: a front group having a first lens group including, in the order from the object side, a first lens element having a negative refracting power, a second lens element having a negative refracting power, and a third lens element having a positive refracting power, the front group having a negative refracting power as a whole, at least one surface of the lens elements of the front group being aspherical; and a rear group including, in the order from the object side, a second lens group having a positive refracting power, a third lens group having a negative refracting power and a fourth lens group having a positive refracting power, the rear group having a positive refracting power as a whole. When variable power operation is performed from the wide angle end side to the telephoto end side, lens groups move relatively along the optical axis so that air space between the first lens group and the second lens group reduces, air space between the second lens group and the third lens group increases, and air space between the third lens group and the fourth lens group reduces.
