The leaks of the last couple of days were correct, as this morning Sigma officially announced their latest Art prime, the 20mm F/1.4 DG HSM. The new lens is set to be available in late November, and will be available in Canon, Nikon, and Sigma mounts.


Joining the 24mm, 35mm, and 50mm, this new 20mm F/1.4 Art prime continues with the design and build styling that we have come to expect from the Sigma Art line. An interesting piece to this lens is the large front element and integrated lens hood.

Sigma 20mm F/1.4 Art Specs

  • EF/F/SA Mounts
  • Aperture Range: f/1.4 to f/16
  • Two FLD Elements and Five SLD Elements
  • Two Aspherical Elements
  • Super Multi-Layer Coating
  • Hyper Sonic AF Motor, Manual Override
  • Rounded 9-Blade Diaphragm
  • TSC Material, Brass Bayonet Mount
  • Built-In Petal-Shaped Lens Hood
  • Compatible with Sigma USB Dock


The front element does not have a filter thread, so it will NOT be compatible with standard filters. This will be a major disadvantage to landscape photographers who will need the ability to use filters for their work. It is a real shame though too; the 20mm FoV is a great landscape view and the low distortion being talked about here would be great.

So if landscape photographers are likely not going to be interested in this lens out of the box, who is this lens for?  Astro-photographers, who have almost no need for filters, will love this lens. It could also be pretty useful as an environmental portrait lens on the wider side of the spectrum.

In typical Sigma fashion, this lens is a great deal , coming in at only $899 in the US. It will be hitting stores in late-November too, perfect for a holiday gift to yourself.

If you are interested, you can pre-order the lens now over on B&H here.
