Sigma 30mm f/1.4 DC “A” review: Updated fast prime for APS-C shooters improves on both build and image quality

The Sigma 30mm f/1.4 DC "A" is yet another lens to undergo Sigma's Global Vision makeover. An updated version of the popular Sigma 30mm f/1.4 EX DC HSM, the new version gets an "Art" Series designation, along with updated construction using Sigma's Thermally Stable Composite Material, new optical layout and compatibility with Sigma's USB Dock configuration and adjustment system.

As expected, the Sigma 30mm f/1.4 DC "A" comes in a variety of flavors for APS-C cameras including Canon, Nikon and Sigma camera mounts. The previous model also came in Sony Alpha and Pentax mounts, but these are currently not available for the new version.

Overall, the new Sigma 30mm ƒ/1.4 DC "A" is a fantastic APS-C fast prime lens that delivers great image quality with nice, sharp images, low vignetting and only slight barrel distortion. Cosmetic updates and optical reconfiguration are the biggest changes. The new Global Vision redesign gives this lens a very high quality build, which feels great in the hand. Sigma's Thermally Stable Composite Material helps make for a strong yet lightweight construction that still keeps the same feel as an all-metal lens.

The new Sigma 30mm prime lens takes 62mm filters like its predecessor does, and weighs just slightly more. And like most Sigma lenses, this one is available for a nice, budget-friendly price of around $499 and ships with front and rear caps, a lens hood and a soft case.
