Sigma has officially announced the 20mm f/1.4 DG HSM lens for full-frame DSLR cameras.
Sigma 20mm f/1.4 DG HSM Art lens design comes with a robust physical construction. Comprised of 15 elements in 11 groups, the lens design includes both “F” Low Dispersion (FLD) and Special Low Dispersion (SLD) glass to significantly reduce chromatic and spherical aberrations, as well as limit distortion for clean, sharp, and evenly illuminated imagery.
A rounded nine-blade diaphragm helps to produce an attractive out-of-focus quality.Petal-shaped lens hood helps to reduce lens flare when working in strong lighting conditions and also offers some protection to the front element of the lens.
The lens is constructed using a Thermally Stable Composite (TSC) material, along with traditional metals, for greater precision and use in wide temperature variations.
