A Review of the New Sigma 20mm f/1.4 DG DN Art Lens

Sigma recently announced two new lenses, the 20mm f/1.4 DG DN Art and 24mm f/1.4 DG DN Art, both of which offer impressive image quality combined with very wide apertures, making them intriguing options for landscapes, astrophotography, and more. This great video review takes a look at the 20mm lens and the sort of performance and image quality you can expect from it in practice. 

Coming to you from Christopher Frost, this excellent video review takes a look at the 20mm f/1.4 DG DN Art lens. As the widest full frame lens with an f/1.4 aperture, the 20mm Art should appeal to quite a few photographers who need a wide angle of view combined with a lot of light-gathering power. It comes with a range of features, including:

  • Mounts: Sony E, Leica L
  • 17 elements in 15 groups
  • Two SLD elements and three aspherical elements, including one double-sided aspherical element
  • Manual Focus Lock
  • Lens heater retainer for extended nighttime shooting without condensation
  • Dust- and splash-resistant construction and water- and oil-repellent coating
  • Aperture ring lock
  • Focus mode switch
  • Customizable button
  • Super Multi-Layer Coating
  • 11-blade rounded diaphragm
  • Rear filter mount

Altogether, the 20mm f/1.4 Art looks like quite an impressive option. Check out the video above for Frost's full thoughts on the lens.
