Abstract: A compact zooming optical system, an optical apparatus and a method for manufacturing the zooming optical system having a vibration reduction function, a high zooming ratio, a wide-angle view and superb optical performance are provided, the system including, in order from an object side: a first lens group G1 having positive refractive power; a second lens group G2 having negative refractive power; a third lens group G3 having positive refractive power; and a fourth lens group G4 having negative refractive power; upon zooming from a wide-angle end state to a telephoto end state, a distance between the first lens group G1 and the second lens group G2, a distance between the second lens group G2 and the third lens group G3 and a distance between the third lens group G3 and the fourth lens group G4 being respectively varied; the third lens group G3 having, in order from the object side, a first segment group G31 having positive refractive power and a second segment group G32; the second segment group G32 being moved to have a component in a direction perpendicular to the optical axis; and predetermined conditional expressions being satisfied.
