Fast f/1.4 Aperture Wide Angle. The Sigma 24mm f/1.4 DG HSM Art for Canon’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, nature, interior, and architectural photography. Using a APS-C sensor camera? You’ll have a focal length equivalent to 38.4mm.

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. A pair of aspherical elements helps to eliminate sagittal coma flare, distortion, and axial chromatic aberration. Three “F” Low-Dispersion elements and four Super Low-Dispersion glass 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. As part of Sigma’s Global Vision series, 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.
