<p>PROBLEM TO BE SOLVED: To provide a zoom lens or the like that has a chromatic aberration excellently corrected in both occasions of an anti-tremor and a non anti-tremor, and includes high optical performance.SOLUTION: A zoom lens has: a first lens group G1 that has a negative refractive power; a second lens group G2 that has a positive refractive power; a third lens group G3 that has the negative refractive power; and a fourth lens group G4 that has the positive refractive power, in order from an object side. Upon zooming from a wide-angle end state to a telephoto-end state, a space between the first lens group G1 and the second lens group G2 varies, a space between the second lens group G2 and the third lens group G3 varies and a space between the third lens group G3 and the fourth lens group G4 varies. The second lens group G2 has: a front side lens group G2F; an aperture stop S; and a rear side lens group G2R, in order from the object side. The front side lens group G2F and the rear side lens group G2R have at least one negative lens, respectively, and at least some lenses of the rear side lens group G2R move so as to include a component of a direction orthogonal to an optical axis.</p> |
