Abstract

The zoom lens includes, in order from a position closest to an object side to an image side: a first lens group that has a positive refractive power; a second lens group that has a negative refractive power; an intermediate group that has a positive refractive power; and a subsequent group that has a negative refractive power. The first lens group moves during zooming. The second lens group consists of, in order from the object side to the image side, a front group of the second lens group which does not move during image blur correction and an image stabilization group which moves during image blur correction and has a negative refractive power. The zoom lens satisfies predetermined conditional expressions.
