Sigma Has Announced An Incredibly Fast 20mm f/1.4 Full-Frame Lens

Sigma has added yet another lens to their higher-end Art series, this time a wide angle full-frame 20mm that opens up to an f/1.4 aperture.

It's rare to find really wide angle full-frame still lenses even remotely this fast, so the fact that Sigma has gotten this to an f/1.4 (and under $1,000) is pretty amazing. Most 20mm lenses are around an f/2 or f/2.8, with Nikon making a particularly speedy 20mm f/1.8. There isn't a giant difference between f/1.4 and f/1.8, but the fact that all of the prime lenses in the Art series have consistent f1/.4 apertures is fantastic, and this one should fit nicely with the 24mm f/1.4, 35mm f/1.4, and 50mm f/1.4 lenses already in the series. This 20mm will come in Canon EF, Nikon F, and Sigma SA mounts.

Here are the specs:
