description An optical system has, sequentially from an object side to an image side, a first lens group including at least one lens and having a negative refractive power, a second lens group including at least one lens and having a positive refractive power, and a third lens group including at least one lens and having a negative refractive power. During focusing, distances from the first lens group and the third lens group to an imaging plane on an optical axis are fixed, and the second lens group is movable along the optical axis.
