Sigma Announces a New Addition to Their 'Art' Line, the World's Widest f/1.4 Lens

Landscape, street, and astrophotographers have reason to rejoice. Today, Sigma announced the latest addition to their much-lauded "Art" line of lenses, the 20mm f/1.4 DG HSM Art, making it the world's widest full frame f/1.4 lens. Coupled with some other intriguing design characteristics, this looks to be another hit for the already popular line of lenses.

Sigma has been been on a roll the last few years. With their revamped market strategy, they have become not only a respected manufacturer of quality lenses, but also a direct threat to Canon and Nikon with their highly competitive prices. We've also seen some great innovation from them, including the world's first full frame f/2 zoom lens, the 24-35mm f/2 DG HSM Art.

Today, that innovation continues with the world's widest full frame f/1.4 lens. It's very clear that Sigma considered all the potential uses of this lens in its design, which includes two FLD ("F" Low Dispersion, Sigma's highest quality LD glass) and five SLD (Special Low Dispersion) elements to correct chromatic aberrations, nine rounded aperture blades for pleasing out-of-focus rendering, and a design that minimizes chromatic aberration.

That last point makes this a potential dream lens for astrophotographers, who frequently have to make the choice between wide apertures or wide angle. By its nature, astrophotography demands fast and wide lenses. Currently, astrophotographers frequently go one of two routes, the first being an ultra wide angle lens, such as the Canon 14mm f/2.8L II, or one of Samyang's excellent offerings. The second route is to choose a more standard length lens that trades field of view for extra stops, namely the , or another of Samyang's choices. This lens offers some of the best of both worlds, however. Sigma seems to have been keenly aware of this, as chromatic aberration, which tends to stretch point sources of light (think stars that look like comets), has been intentionally minimized in this lens. This, coupled with its wide and fast design, could make the lens a triple threat for astrophotography. Check out the full specifications below: 

  • Designed for 24×36 DSLR cameras
  • Lens construction: 15 elements in 11 groups
  • One large-diameter aspherical element
  • Two FLD elements and five SLD elements to best correct chromatic aberrations
  • In-lens HSM autofocus motor. New mechanism for full-time manual override in autofocus mode
  • Total length: 129.8mm
  • Maximum diameter: 90.7mm
  • Weight: 950g
  • 9 diaphragm blades, rounded
  • Maximum magnification: 1:7.1 (0.14x)
  • Designed to minimize flare and ghosting
  • Very low distortion
  • Designed to minimize coma aberration
  • Available in Canon, Nikon and Sigma mounts for $899

Pre-orders are open now with delivery expected in the beginning of December 2015.

"... the world's first FULL FRAME f/2 zoom lens..." - 18-35/1.8 is not full frame lens.

Bartosz Dittmar's picture

Yeah, but the 24-35mm f/2 is full frame :)

I am thinking about this for my Canon, but not sure about biting, because I'm also considering moving over to a mirrorless system. I like the specs on this lens though.

Yup, I'll probably be selling my Nikkor 28mm 1.8G to replace it with this bad boy. Can't wait to see its performance first though.

Okay, this made my day. My preorder is in and I'll get mine before you do!

What a tease. Where's the 85mm plz

This is a straight-up astro lens. I can't think of any other real primary use for this. Regular landscape photographers use tripods and stop down.

Nikon users also have an *amazing* 20mm f/1.8 lens that is a couple hundred bucks less. This is a very cool technical exercise and IS a big deal for astronomy, but I'm not sure who this is for otherwise.

I would love to see its performance, and more importantly the coma before I call it an astrophotography lens.

This seems strange having so recently released the 24mm Art. What am I missing here?

Kyle Medina's picture

It's a niche lens, astrophotography.

As awesome as this lens is. Does this mean they'll finally shift to a 85/100/135/200 Art finally. So many people have been waiting for one of those.

The 120-300 is an awesome bit of kit but it's bigger and heavier than my 85mm and 135mm combined

Can't wait to rent this bad boy!
