Sigma 50mm f/1.4 EX DG HSM AF: Lens Test - - PopPhotoOctober 2008 (http://www.popphoto.com/cameralenses/5621/sigma-50mm-f14-ex-dg-hsm-af-lens-test.html?cid=10)

Can I use this lens with my Nikon D60? Also, is this the kind of lens that rarely needs to be focused, that I've heard so much about?

Thanks,

Heath
