The Sigma 50-500mm f/4-6.3 EX DG HSM is a super-telephoto zoom lens produced by Sigma Corporation. It is commonly known as the "Bigma" because of its long and heavy body. It contains four SLD (Special Low Dispersion) glass elements to provide correction for chromatic aberration. It is aimed toward advanced consumers.
The Bigma was originally released by Sigma in 2001. Over the years, it has gone through several iterations and improvements. This includes the 2006 DG model which is optimized for digital cameras. In 2010, Sigma added built-in optical stabilization (OS) to the Bigma.
