Sigma has updated their 105mm EX DG macro lens to the 105mm EX DG OS HSM version. Adding to the features of the original, the updated lens sports Sigma's optical stabilization (OS) system, to provide better hand-holding lens performance. Also it's compatible with all  of Sigma's APO Tele-Converters.  There's also true 1:1 macro capture featuring floating focus for superb optical quality at all focal ranges and the lens barrel is now splash proof. There's also HSM for quick near silent auto focusing even on Nikon cameras without a built-in motor and a full-time manual override. It can be mounted on both APS-C and Full Frame Cameras
