ZOOM LENS, OPTICAL DEVICE COMPRISING SAME AND METHOD FOR MANUFACTURING ZOOM LENS

WIPO Patent Application WO/2010/013435

A1

Provided is a zoom lens which enables blurring correction by shifting an image by an optical system that is movable so as to have a component in the direction orthogonal to the optical axis to thereby achieve higher variable power and reduced performance degradation. The zoom lens comprises a first lens group (G1) having positive refracting power, a second lens group (G2) having negative refracting power, a third lens group (G3) having positive refracting power, a fourth lens group (G4) having negative refracting power, and a fifth lens group (G5) having positive refracting power which are arranged in order from the object side, wherein a lens group that is at least part of the fourth lens group (G4) is movable so as to have a component in the direction orthogonal to the optical axis, when the power is varied from a wide-angle end state to a telephoto end state, the distances between the respective lens groups change, and the conditional expression 0.01
