摘要： A variable magnification optical system having at least a first lens group having a negative optical power, a second lens group having a positive optical power, a third lens group having a negative optical power, and a fourth lens element having a positive optical power, in the optical axis direction in zooming, keeps the third lens element immobile with respect to an image surface while moving at least the second lens group and the fourth lens group, whereby: an interval between the first lens group and the second lens group decreases, an interval between the second lens group and the third lens group increases, and an interval between the third lens group and the fourth lens group decreases. Moreover, the variable magnification optical system moves the third lens group in an in-surface direction vertical to the optical axis direction to thereby correct shake resulting from imaging on the image surface, and fulfills predetermined conditional formula.
