Sigma first ventured into the mirrorless space with the release of two lenses for Sony E-Mount and Micro 4/3 in January of 2012 with the 19mm f/2.8 and 30mm f/2.8 EX DN lenses.  Around a year later, they released updated versions of these lenses with a new body style, and perhaps minor changes to coatings, though officially no optical changes were made.  Today, I’m going to take a look at the newer version of the 30mm lens: The Sigma 30mm f/2.8 DN Art for Sony E-mount.  This lens is relatively small, incredibly inexpensive, and provides a normal focal length with a field of view equivalent to a 45mm lens on a full frame camera.  It also may be one of the better bargains in photography today.

If you’re not familiar with my reviews, I review from a real world shooting perspective. You won’t find lens charts or resolution numbers here. There are plenty of other sites that cover those. I review products on how they act for me as a photographic tool in real-world shooting.
