Abstract

See full text

A zoom lens includes, in order from an object side along an optical axis, a first lens group G1 having positive refractive power, a second lens group G2 having negative refractive power, and a third lens group G3 having positive refractive power. Upon zooming from a wide-angle end state W to a telephoto end state T, a distance between the first lens group G1 and the second lens group G2 increases, and a distance between the second lens group G2 and the third lens group G3 decreases. Given conditions are satisfied. Accordingly, a zoom lens having high optical performance with suppressing variations in aberrations, an optical apparatus equipped therewith, and a method for manufacturing the zoom lens are provided.
