A favored wide-angle prime, the 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 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.
