Fast f/1.4 Aperture Wide Angle. The Sigma 28mm f/1.4 DG HSM Art for Nikon’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 and street photography. Using a DX-format camera? You’ll have a focal length equivalent to 42mm.

High-Quality Optics. As a part of Sigma’s Art lens line, this lens goes through Sigma’s rigorous A1 testing to ensure high image quality. Three aspherical elements help to eliminate sagittal coma flare, distortion, and axial chromatic aberration, while two “F” Low-Dispersion elements work in unison to correct for chromatic aberrations throughout the entire focusing range while ensuring high image sharpness, clarity, and contrast. The Super Multi-Layer Coating minimizes lens flare and ghosting, helping to provide high 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.

Dock Compatible. This lens is compatible with the Sigma USB Dock for Nikon F Lenses, allowing you fine-tune certain parameters through the Sigma Optimization Pro software.
