Zoom lens, imaging device and method for manufacturing the zoom lens

Abstract

The present invention has, in order from an object, 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, wherein zooming is performed by changing an air gap between the lens groups, the fourth lens group (G4) includes, in order from the object, a lens component (La) having positive or negative refractive power, a positive lens component (Lb), and a positive lens component (Lc) having a convex surface facing the object, and the following conditional expression is satisfied: 0.00<(Rc2−Rc1)/(Rc2+Rc1)<1.00 where Rc2 denotes a radius of curvature of an image side surface of the positive lens component (Lb) which constitutes the fourth lens group (G4) and has the convex surface facing the object, and Rc1 denotes a radius of curvature of an object side surface of the positive lens component (Lb) which constitutes the fourth lens group (G4) and has the convex surface facing the object.
