This is a review I put together for shotkit.com
In 2019, Sigma released their first DG DN lens – the Sigma 35mm f/1.2 DG DN ART.
This was one of the first Sigma lenses to be made for a full-frame mirrorless mount, as opposed to the DSLR lenses Sigma produced previously which had a built-in Sony adapter.
The 35mm was followed by a Sigma 14-24mm f/2.8 DG DN ART, 45mm f/2.8 DG DN Contemporary, and now the Sigma 24-70mm f/2.8 DG DN ART.
This is likely to be an outcome of Sigma’s involvement in the L mount alliance.
This new approach is identifiable by the combination of DG DN delineation. Prior to this, lenses have had either DG or DN – the DG indicating full-frame and DN indicating mirrorless.
These are the first lenses to appear with both.
