PROBLEM TO BE SOLVED: To provide a zoom lens with a high magnification, attaining miniaturization, wider angle and high aperture ratio, and capable of satisfactorily correcting various aberrations over an entire variable power region and corresponding to a solid state image sensor allowing full high-definition type photographing.SOLUTION: The zoom lens includes, in order from an object side, a first lens group Ghaving positive refractive power, second lens group Ghaving negative refractive power, a third lens group Ghaving positive refractive power, a fourth lens group Ghaving positive refractive power, and a fifth lens group Ghaving negative refractive power. By satisfying predetermined conditions, a zoom lens with high optical performance can attain miniaturization, wider angle and high aperture ratio, and correspond to a solid state image sensor allowing full high-definition type photographing. |
