PROBLEM TO BE SOLVED: To provide a zoom lens that is small in size as well as excellent in optical performance, optical equipment, and a method for manufacturing a zoom lens. ! SOLUTION: The zoom lens includes, successively arranged 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; and upon varying powers from a wide angle end state to a telephoto end state, intervals of these lens groups vary, and the fourth lens group G4 once moves toward the object side and then moves toward an image side. The third lens group G3 includes, successively arranged from the object side along the optical axis, a positive lens component L31, a negative lens component L32, and a positive lens component L33. The zoom lens satisfies conditional expressions (1): 1.00<f3/fw<2.10 and (2): 0.25<(-f3b)/f3<0.60. ! COPYRIGHT: (C) |
