Fast f/1.4 Aperture Wide Angle. The Sigma 20mm f/1.4 DG HSM Art’s fast f/1.4 aperture enables great low-light performance, wide-angle images, and shallow depth of field. The wide-angle perspective is popular for landscape, nature, interior, and architectural photography. Using a crop-sensor camera? You’ll have a focal length equivalent to 30mm.
High Build and Image Quality. As a part of Sigma’s Art lens line, the DG HSM goes through Sigma’s rigorous A1 testing, ensuring high image quality. A pair of aspherical elements helps to eliminate sagittal coma flare, distortion, and axial chromatic aberration. Two “F” Low-Dispersion elements and five Super Low-Dispersion glass elements correct for chromatic aberrations throughout the entire focusing while ensuring high image sharpness, clarity, and contrast. The Super Multi-Layer Coating minimizes lens flare and ghosting, helping to provide high contrast and color accuracy.
Hyper Sonic Motor Autofocus System. Provides fast, smooth, and quiet operation in a wide variety of shooting situations. You can also manually override the autofocus motor at any time by rotating the focusing ring, giving you quick fine-tuning ability.
