摘要： A variable power optical system used for an optical apparatus, such as a camera, includes, in order from an object: a first lens group having positive refractive power; a second lens group having negative refractive power; a third lens group having positive refractive power; and a fourth lens group having positive or negative refractive power. The distances between lens groups change upon zooming from a wide-angle end state to a telephoto end state. The third lens group comprises, in order from the object, a first positive lens, a second positive lens, a first negative lens, a second negative lens and a third positive lens. The third lens group includes a vibration-isolating lens group which can move so as to have a movement component in a direction orthogonal to the optical axis upon correcting camera shake.

The third lens group (G3) includes: an intermediate group (G3b) constituted by a positive lens, a negative lens, a negative lens, and a positive lens; and an image side group (G3c) having negative refractive power and disposed to an image side of the intermediate group (G3b). Upon focusing, the position of the intermediate group (G3b) with respect to the image plane is fixed and the image side group (G3c) moves along the optical axis.

The system including, in order from an object, a first group G1 having negative refractive power, a second group G2 having positive refractive power, a third group G3 having negative refractive power, and a fourth group G4 having positive refractive power. An aperture stop S is disposed between the second group G2 and the fourth group G4. Upon zooming from a wide-angle end state to a telephoto end state, each group is moved such that a distance between the second group G2 and the third group G3 increases, a distance between the third group G3 and the fourth group G4 decreases, and the aperture stop S is moved together with the third group G3.
