An exemplary internally focusing lens system includes, in order from the object side to the image side, a first lens group with positive refractive power, a second lens group with negative refractive power, and a third lens group with positive refractive power. The third lens group includes one lens element. The second lens group is movable toward the image side and the first and third lens groups remain stationary during focusing of the lens system from an infinitely distant object to a nearby object.
