Abstract:
A zoom lens including, in order from an object side, a positive first lens group G 1 , a negative second lens group G 2 , a composite positive lens group which includes, at the most object side, a positive third lens group G 3 , which is consisting of one or more lens groups having positive refractive power, and which has positive refractive power as a whole, and a composite negative lens group which includes, at the most object side, a negative A lens group, which additionally includes at least a negative B lens group, and which has negative refractive power as a whole. In the zoom lens, changing focal length is performed by varying the distances between the lens groups, and a predetermined condition is satisfied.

Claim (Index 10):
The zoom lens according to  claim 1 , wherein the lens groups having negative refractive power included in the composite negative lens group consists of the negative A lens group and a negative B lens group.
