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.

Sigma Dock Compatibility. This lens is compatible with the Sigma USB Dock for Canon EF Lenses (separate rental item), allowing you to adjust certain parameters through the Sigma Optimization Pro software.
