A zoom lens has a plurality of lens groups comprising, in order from an object, a first lens group (G1) having a negative refractive power, a second lens group (G2) having a negative refractive power, a third lens group (G3) having a positive refractive power, and the final lens group (G4) having a negative refractive power, the final lens group (G4) is located closest to an image in the plurality of lens groups, and the distance between respective lens groups in the plurality of lens groups varies at varying power. An imaging device is provided with a zoom lens and an imaging element having an imaging surface. |
