Abstract:
The present invention relates to a zoom lens which can shift images using a movable optical system so as to have components orthogonal to the optical axis, and can correct hand motion blur, and minimizes the deterioration of performance while attempting higher variable power. This zoom lens has, in order from an object, 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, a fourth lens group G4 having negative refractive power, and a fifth lens group G5 having positive refractive power, and at least a part of the fourth lens group G4 can move so as to have components orthogonal to the optical axis, and a distance between each lens group is changed upon zooming from a wide-angle end state to a telephoto end state, and the following conditional expression is satisfied, 0.01
