Versions
The lens was originally announced by Sigma in 2000 at that year's Photo Expo and released in 2001. The lens has a variable minimum focusing distance and varifocal design, which was remedied partially through autofocusing technology.[2]
Over the years, it has gone through several iterations and improvements. This includes the 2006 DG model which has upgraded coatings optimized for digital cameras. In 2010, Sigma added built-in optical stabilization (OS) to the lens.[2]
