A zoom lens ZL installed in an electronic still camera 1 and the like includes, in order from an object side, 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, and a fourth lens group G4 having positive refractive power, a given conditional expressions are satisfied, where r3F denotes a radius of curvature of an image side lens surface of the cemented lens in the third lens group, and r3R denotes a radius of curvature of an object side lens surface of the negative meniscus lens in the third lens group, thereby providing a zoom lens having excellent optical performance, an optical apparatus equipped therewith, and a method for manufacturing the zoom lens. |
