Abstract:
A zoom optical system (ZL) comprises a first lens group (G 1 ) having positive refractive power, a second lens group (G 2 ) having negative refractive power, a third lens group (G 3 ) having positive refractive power, a fourth lens group (G 4 ) having negative refractive power, and a fifth lens group (G 5 ) having positive refractive power that are disposed in order from an object. Upon zooming from a wide angle end state to a telephoto end state, the lens groups are moved along an optical axis to change distances between the lens groups. The fifth lens group (G 5 ) comprises at least one positive lens and at least one negative lens. Certain conditional expressions are satisfied.

Claim (Index 22):
The zoom optical system according to  claim 1 , wherein the fourth lens group includes at least an aspherical lens surface.
