In a zoom lens comprising 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, the first to fifth lens groups (G1 to G5) are respectively moved along the optical axis so that a distance between the first lens group (G1) and the second lens group (G2), a distance between a distance between the second lens group (G2) and the third lens group (G3), a distance between the third lens group (G3) and the fourth lens group (G4), a distance between the fourth lens group (G4) and the fifth lens group (G5) respectively changes upon zooming from a wide-angle end state to a telephoto end state, so that a conditional expression “0.25
