Sigma 28mm f/1.4 DG HSM Art Lens for Nikon
A favored wide-angle prime, the Nikon F-mount Sigma 28mm f/1.4 DG HSM Art Lens is a versatile lens with a classic broad field of view that suits everything from street shooting to landscape photography. Impressively bright, the fast f/1.4 maximum aperture is ideal for working in low-light conditions and also offers greater control over the depth of field for isolating subject matter. An advanced optical design is employed, which uses both low-dispersion glass and aspherical elements to reduce chromatic and spherical aberrations for greater clarity and sharpness. A Super Multi-Layer Coating is also featured and suppresses ghosting and flare for improved contrast and color accuracy.
In addition to its optical merits, this 28mm f/1.4 also sports a Hyper Sonic Motor to produce quick, smooth, and quiet autofocus performance with full-time manual focus override. The physical design features a brass bayonet mount, which offers rigidity and mounting precision along with a seal to guard against dust and moisture. Additionally, a rounded nine-blade diaphragm contributes to a pleasing bokeh quality.
Two F Low Dispersion (FLD) and three Special Low Dispersion (SLD) elements are featured in the optical design and help to reduce color fringing and chromatic aberrations for improved clarity and color accuracy
Three aspherical elements are used to help limit distortion and spherical aberrations and also contribute to greater overall sharpness and accurate rendering
Super Multi-Layer Coating has been applied to lens elements in order to minimize lens flare and ghosting and contribute to producing contrast-rich and color-neutral imagery, even in backlit conditions
