Abstract:
A zoom lens system includes a negative first lens group, a positive second lens group, a negative third lens group and a positive fourth lens group, in that order from the object side. Upon zooming from a short focal length extremity to a long focal length extremity, at least the first lens group, the second lens group and the fourth lens group are moved in the optical axis direction of the zoom lens. The third lens group includes a negative first sub-lens group and a negative second sub-lens group, in that order from the object side, the second sub-lens group is provided with a negative single lens element and a positive single lens element, and an air lens is formed between the negative single lens element and the positive single lens element.

Claim (Index 2):
The zoom lens system according to  claim 1 , wherein said second sub-lens group comprises a negative single lens element having a concave surface on the image side, and a positive single lens element having a convex surface on the object side, in that order from the object side, wherein a meniscus shaped air lens having a convex surface on the object side is formed between said negative single lens element and said positive single lens element.
