Sigma 20mm 1.4 Art
According to our informations a new Sigma 20mm 1.4 Art wide angle lens is coming in the near future. The field of view is 94.5° on Full frame cameras.
This focal length is very interesting. The lens has 9 aperture blades. With the bright f/1.4 aperture it is not a light lens, the weight of the lens is 950g (2.09 lbs.)
The optical design is 15 lens elements in 11 groups which means it is not a simple lens. If Sigma can keep the quality of it’s latest lenses like the Sigma 35mm f/1.4 Art , Sigma 50mm f/1.4 Art or the Sigma 18-35mm f/1.8 Art it will be a HOT SELLER.
The story, I guess will be about how sharp the corners are, and the huge vignetting, which is expected for such a lens, but Sigma included 2 FLD and 5 SLD (!) glass in the optical design to make things happen. For those who has no information about the newest Sigma Art lenses, these lenses put Canon, Nikon lenses to shame even wide open. See my reviews at above links about these lenses, very few lenses out there to compete with these quality. Pin sharp f/1.4 performance, which is simply not existed before. For example at 50mm no other product can be even close to Sigma.
But this 20mm has very strong rivals namely the Wonderful Nikon 14-24mm f/2.8 and the new Canon 11-24mm f/4. Sigma’s big benefit is the price, because both of these lenses play in the more expensive region. The Sigma costs 899 USD, while the Nikkor 14-24 f/2.8G is 1997 USD, the new Canon 11-24mm f/4 is 3000 USD.
The lens will be available in Canon EF, Nikon F, and Sigma SA mounts.
Sigma 20mm 1.4 Art price

Sigma 20mm 1.4 Art release date
The lens will be available from November 2015 according to our information.
