发明名称 Zoom lens and imaging apparatus
摘要 Provided is a zoom lens that has a plurality of lens groups and performs zooming by changing spaces between the plurality of lens groups. A final lens group closest to an image side includes, in order from an object side to an image side: a first partial lens group that has a negative refractive power; a second partial lens group that has a positive refractive power; and a third partial lens group that has a positive refractive power. Image blur is corrected by shifting the second partial lens group in a direction substantially perpendicular to an optical axis. Assuming that a focal length of the first partial lens group is fGF, a focal length of the second partial lens group is fGS, and a focal length of a whole lens system of the lens groups in a telephoto end state is ft, the following expressions are satisfied:−0.24<fGF/ft<−0.09; and 0.12<fGS/ft<0.32.
