Abstract: A wide-angle zoom lens includes: a first lens group having a negative refractive power, a second lens group having positive refractive power, a third lens group having a negative refractive power and a fourth lens group having a positive refractive power in that order from an object side. The second lens group is configured with a front group, a stop and a rear group having a positive refractive power in that order from the object side. Magnification change is performed by changing distances among the lens groups.

Abstract: A zoom lens includes sequentially from an object side, a first lens group having a positive refractive power, a second lens group having a negative refractive power, a third lens group having a positive refractive power, a fourth lens group having a negative refractive power, a fifth lens group having a positive refractive power, and a sixth lens group having a negative refractive power. The zoom lens varies the interval between the lens groups to perform zooming; shifts the second lens group in a direction substantially orthogonal to the optical axis to correct image blur occurring with optical system vibrations; and satisfies given conditions, enabling a compact size and a high zoom ratio to be achieved while improving imaging performance.
