ZOOM LENS AND IMAGING APPARATUS

PROBLEM TO BE SOLVED: To provide a zoom lens with a vibration-proof function which is completely miniaturized. SOLUTION: The zoom lens has a first lens group G1 having positive refractive power, a second lens group G2 having negative refractive power, a third lens group G3 having positive refractive power and a fourth lens group G4 having positive refractive power in order from an object side. The first lens group G1 is equipped with a lens group Gc having positive refractive power and a bending optical system P bending an optical axis at about 90° in order from the object side. The third lens group G3 is constituted of a fixed lens group Ga having positive refractive power and a movable lens group Gb having positive refractive power. During zooming operation, the second lens group G2 and the fourth lens group G4 move along the optical axis. During vibration-proof operation, the movable lens group Gb of the third lens group G3 moves in a direction orthogonal to the optical axis. COPYRIGHT: (C)2008,JPO&INPIT
