Abstract

A sufficiently compact zoom lens equipped with a vibration-control function is provided. The zoom lens includes, in sequence 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 refractive power. The first lens group includes, in sequence from the object, a lens group having positive refractive power and a bending optical system for bending an optical axis to essentially an angle of 90°. Moreover, the third lens group has a stationary lens group having positive refractive power and a movable lens group having positive refractive power. During zooming operation, the second lens group and the fourth lens group are moved along the optical axis. During vibration-control operation, the movable lens group of the third lens group is moved in a direction orthogonal to the optical axis.
