PROBLEM TO BE SOLVED: To provide a zoom lens which is small in size, light in weight and high in performance, while having a high magnification and to provide an imaging apparatus.SOLUTION: A zoom lens has, in order from an object side, a first lens group G1 having a positive refractive power, a second lens group G2 having a negative refractive power, a third lens group G3 having a positive refractive power, and a fourth lens group G4 having a positive refractive power. An interval between the adjacent lens groups of the first to fourth lens groups is changed to perform zooming. The fourth lens group G4 comprises, in order from the object side, a first positive lens L41, a first negative meniscus lens L42, and a cemented lens comprising a second negative meniscus lens L43, the convex surface of which is oriented to the object side and a second positive lens L44. |
