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 5):
The zoom optical system according to  claim 1 , wherein upon zooming from the wide angle end state to the telephoto end state, the lens groups are moved along an optical axis so as to\n increase the distance between the first lens group and the second lens group, decrease the distance between the second lens group and the third lens group, increase the distance between the third lens group and the fourth lens group, and decrease the distance between the fourth lens group and the fifth lens group.
