Nikon D3100 Lenses that have a focus motor

"It focuses very fast, and very quiet. Sigma did something right with the HSM (not like my other Sigma lens that hunts to focus and is pretty noisy). The images come out very sharp prior to any post-processing and colors seem very accurate. All in all, I love this lens. Worth every penny!"
