Abstract
A zoom lens consists of 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 positive refractive power, and a fifth lens group having positive refractive power in this order from an object side. The third lens group consists of a 3-1st lens group having positive refractive power and a 3-2nd lens group having negative refractive power in this order from the object side. A hand shake blur is corrected by moving the 3-2nd lens group in a direction perpendicular to optical axis. Magnification is changed by changing distances between the lens groups while the fifth lens group is fixed.
