Sigma 20mm f/1.4 Art Lens Review: Ultra-wide, ultra-fast & ultra-sharp


posted Friday, November 6, 2015 at 6:24 PM EDT


Adding to their arsenal of high-quality, ultra-fast primes, Sigma's new 20mm f/1.4 Art lens is now their widest of the bunch, joining the previous 24mm, 35mm and 50mm f/1.4 Art-series lenses. Not only is it Sigma's widest full-frame Art lens, but its also the camera industry's first ultra-wide angle lens with an f/1.4 aperture for full-frame DSLRs. 

We've now put the lens through its paces in our testing lab, and after an earlier teaser with some high-resolution gallery photos with the Canon 5DS, our test results confirm was we expected: this lens is fantastic. Images are very sharp, and yes, you have to contend with some corner softness at f/1.4 on a full-frame camera and some vignetting, but elsewhere down the aperture range, things looking spectacular -- and rival some pricy offerings from Canon and Nikon along the way.

Offering very high quality images and performance at a rather competitive pricepoint of around $900, the Sigma 20mm f/1.4 Art definitely deserves a closer look, especially if you're in need of an ultra-wide landscape or astrophotography lens.
