Abstract
A zoom lens consists of, in order from an object side to an image 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 positive refractive power; a fifth lens group having a negative refractive power; and a sixth lens group having a positive refractive power. During zooming from the wide angle end to the telephoto end, the distance between the adjacent lens groups in the optical axis direction changes, and the third lens group and the fifth lens group move integrally along the optical axis.
