Sigma Releases World’s First 20mm f/1.4 lens
Sigma has launched a new lens for ultra-high-megapixel DSLRs and ILCs to get the best images possible out of high-end cameras.
Called the Sigma 20mm f/1.4 DG HSM Art, the lens features a 59mm large double aspherical lens that uses the same technology seen in the Sigma 12-24mm F4.5-5.6 EX DG Aspherical HSM and the 18-35mm F1.8 DC HSM Art.
The 20mm f/1.4 lens uses two FLD (F Low Dispersion) elements and 5 SLD (Special Low Dispersion) elements to greatly reduce transverse chromatic aberration. This allows a high contrast, sharp image without any kind of color smearing, and the Super Multilayer Coating helps minimize flare, ghosting, and surface reflections, leading to improved color accuracy.
The minimal distortion makes the lens ideal for landscapes, interiors, and also architecture, but its aperture also allows for great portraits with blurred backgrounds and bokeh effect.
The use of the Hypersonic Motor (HSM) allows for silent, high-speed autofocus, but also gives the option for manual focus without the need to switch with a button.
To improve the lens’ external quality, a Thermally Stable Composite has been used in the construct. Not only does this allow for operation at higher temperatures and prevention of thermal shrinkage/expansion, it also makes the lens much lighter.
As with other Sigma lenses, the 20mm f/1.4 DG HSM Art will be compatible with the Sigma USB Dock, allowing you to tweak individual units for optimum precision.
The lens will be available in November for $899, and supports Canon EF, Nikon F, and Sigma SA cameras.
