A zoom lens system includes, in order from an object side: a first lens group having positive refractive power; a second lens group having negative refractive power; a third lens group having positive refractive power; a fourth lens group having negative refractive power; and a fifth lens group having positive refractive power. Upon zooming from a wide-angle end state to a telephoto end state, a position of the first lens group is fixed. At least a portion of any one of the lens groups is moved in a direction including a component perpendicular to an optical axis, and a given conditional expression is satisfied, thereby providing a zoom lens system capable of excellently suppressing variation in aberrations upon zooming and upon correcting an image blur, an optical apparatus including the zoom lens system, and a method for manufacturing the zoom lens system. |
