HSM (Hypersonic Motor) also focuses quickly and quietly, and internally - without rotating the filter threads. If you want a bag that doesn't look like a camera bag or prefer to make your own DIY solutions, they're worth a look. The Sigma 10-20 was not as sharp as the Nikon 16-85 in the very center of the image at comparable focal lengths (16mm and 20mm) and apertures, although was very close by f/5 and nearly the same at f/8. Naturally there should be some proportion of good samples, but I've never had anything as bad as that before or since.

Canon's 10-22mm zoom tested very well, slightly edging out the Sigma 10-22mm in places, but getting beaten slightly in others.
