Fast f/1.8 Aperture Wide Angle. The Sigma 14mm f/1.8 DG HSM Art’s bright f/1.8 maximum aperture, wide-angle perspective, and fast, flexible performance make it excellent for low-light outdoor shooting and astrophotography. You can also use this lens on APS-C mount cameras, on which it’ll provide a 22.4mm equivalent focal length.

High-Quality Optics. As a part of Sigma’s Art lens line, the 14mm f/1.8 goes through rigorous testing to ensure high image quality. Four aspherical elements help to eliminate distortion and spherical aberrations. Three “F” Low-Dispersion elements and four Super Low-Dispersion glass elements correct for chromatic aberrations and color fringing while ensuring high image sharpness, clarity, and contrast. The Super Multi-Layer Coating minimizes lens flare and ghosting, helping to provide high contrast in strong lighting.

Hyper Sonic Motor Autofocus System. The autofocus system provides fast, smooth, and quiet operation in a broad range 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. The 14mm f/1.8 offers a 10.6-inch minimum focusing distance.
