Okay so i have a nikon d5100 and i am wondering if the Sigma 10-20mm 4-5.6 DC HSM AF lens will auto focus on my camera, its very confusing because i know the sigma has a hyper sonic motor, but it says af not af-s, i thought it had to be af-s to have its own motor and to work on my camera? does anyone have any info on this?
