Abstract
A zoom lens consists of, in order from the 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 positive refractive power, wherein magnification change is effected by changing all distances between adjacent lens groups. The second lens group is moved from the object side toward the image side during magnification change from the wide-angle end to the telephoto end. The position of the third lens group at the telephoto end is nearer to the image side than the position of the third lens group at the wide-angle end.
