After announcing the Sigma 24-35mm f/2 DG HSM Art lens at the beginning of this summer, Sigma has now further strengthened its superb Art series with another innovation - Sigma 20mm f/1.4 DG HSM Art.
This Japanese giant claims that the new Sigma 20mm f/1.4 DG HSM Art is the world's fastest 20mm wide-angle prime lens so far. It is designed for full-frame cameras and it will be compatible with Canon EF, Nikon F, and Sigma mounts.
When it comes to its optical construction, the 20mm f/1.4 DG HSM Art consists of 15 elements in 11 groups, two of which are FLD (F Low Dispersion), and five of which are SLD (Special Low Dispersion), thanks to which the lens deals exceptionally with lateral chromatic aberrations. There is also one double aspherical element, 59mm in diameter, which the company says is traditionally very difficult to construct, and which is intended to maintain accurate drawing. Moreover, the lens elements are overlaid with Sigma's Super Multi-Layer Coating, which keeps flare and ghosting under control, and in return brings high-contrast images even in backlight conditions.
The lens also boasts a 9-blade rounded diaphragm, which results in an attractive blur in the out-of-focus areas of the image, as well as a HSM (Hyper Sonic Motor), which provides silent, but high-speed autofocus. As far as the dimensions and weight of the lens are concerned, they are 90.7 x 129.8 mm, and 950g, respectively.
Bearing in mind its properties, this wide prime lens is aimed at shooting landscapes, starry skies, architecture, but also portraits, close-ups, indoor photography, etc.
The Sigma 20mm f/1.4 DG HSM Art will be available starting from November, and its price will be $899.99.
