Abstract: A zoom optical system comprising, in order from an object side: a first lens group (G1) having positive refractive power; a front-side lens group; an intermediate lens group having positive refractive power; and a rear-side lens group. The front-side lens group is composed of one or more lens groups and has a negative lens group. At least part of the intermediate lens group is a focusing lens group. The rear-side lens group is composed of one or more lens groups. Upon zooming, the first lens group and the intermediate lens group are moved with respect to an image surface, a distance between the first lens group and the front-side lens group is changed, and a distance between the intermediate lens group and the rear-side lens group is changed. The following conditional expression is satisfied: 0.000

Abstract: A variable magnification optical system (ZL) comprises: a first lens group (G1) having negative refractive power; and a rear group (GR) including at least one lens group. When changing the magnification, the distances between adjacent lens groups change. At least one lens group of the rear group (GR) includes a final lens group (GE) having positive refractive power and disposed closest to the image side in the rear group (GR). The variable magnification optical system satisfies the following conditional expression. 0.15

Abstract: A variable magnification optical system includes, in order from an object side, a first lens group having positive refractive power; a second lens group having negative refractive power; and a third lens group having positive refractive power; upon zooming from a wide-angle end state to a telephoto end state, a distance between the first lens group and the second lens group and a distance between the second lens group and the third lens group being varied. The variable magnification optical system further includes a V lens group GV having negative refractive power and being moved to have a component in a direction perpendicular to the optical axis, and an F lens group GF having positive refractive power and being moved along the optical axis upon focusing from an infinitely distant object to a close object, the V lens group GV being disposed on the more object side than the F lens group GF. Thereby, it is possible to provide the compact variable magnification optical system with a high zoom ratio and high performance, an optical apparatus therewith and a method for manufacturing the variable magnification optical system.
