Nikon D5100 Lenses that have a Sigma HSM focus motor

"This is an impressive lens with no obvious cons. The build quality is excellent and image quality and resolution at a variety of distances and macro are at least as good (to my eyes) as Nikon glass. The bokeh is also good especially for a zoom lens."
