Sigma continues to one-up everyone by releasing faster lenses than the OEMs have available. With the new 20mm F1.4 ART, Sigma has a lens that’s two-thirds of a stop brighter than Nikon’s 20mm F1.8G ED and a full two stops brighter than Canon’s 20mm F2.8 USM.

The lens is made of 15 elements in 11 groups, including two large double aspherical elements that make such a fast aperture at such a wide angle possible. There’s 9 rounded aperture blades for smooth out-of-focus elements and a fixed lens hood that requires a special lens cap. And if you’re not a fan of the plastic lens cap, there’s a metal one available separately.

The 20mm F1.4 ART is designed with the latest high-resolution cameras on the market in mind. The width and large aperture might make it a good choice for astrophotography, for example. The lens expected to arrive in December with Canon EF, Nikon F and Sigma mounts for a MSRP of $1249.95.

The New “F1.4” joins SIGMA’s Art line. The Sigma Corporation is pleased to announce the SIGMA 20mm F1.4 DG HSM―the world’s first F1.4 ultra-wide-angle lens for full-frame DSLRs.SIGMA has extensive experience in leveraging its advanced design capabilities and leading-edge technologies to craft large-aperture prime lenses that bring out the full potential of ultra-high-megapixel DSLRs. As its latest achievement in this category, SIGMA has created an ultra-wide-angle lens with F1.4 brightness. With a focal length of 20mm and F1.4 aperture, this lens delivers outstanding large-aperture brightness and bokeh, delivering unprecedented visual experiences. Allowing the photographer to leverage the perspective provided by the wide-angle and the shallow depth of field provided by the large aperture, this lens is ideal not only for such ultra-wide-angle subjects as landscapes and starry skies, but also for snapshots in low light, indoor photography, portraits with a natural bokeh effect, and much more.
