Img 9705a 1000Sigma's new 105mm f/2.8 EX DG OS HSM macro lens is a redesign of an older design, with a few extra features. HSM focusing replaces an older (and slightly confusing) focusing system, and optical stabilization has been added in case you didn't want to lug a tripod into the field. We've put this lens through its paces in our test lab - click here to see our full review of this lens.
