• An ultra-wide zoom lens with a constant f/2.8 aperture, the 14-24mm f/2.8 DG HSM Art Lens from Sigma is an outstanding option for architectural and landscape shooters with full-frame Sigma SA cameras. A part of the esteemed Art-series of lenses, a sophisticated optical design is used that incorporates three FLD, three SLD, and three aspherical elements to help reduce chromatic aberrations and keep distortion under control. A Super Multi-Layer coating has also been applied to suppress lens flare and ghosting for accurate color fidelity and high contrast.

  Complementing the imaging capabilities, the lens sports a Hyper Sonic Motor to produce quick, smooth, and quiet autofocus performance with full-time manual focus override. The lens features a rounded 9-blade diaphragm that gives a smooth look to out-of-focus areas, which stops down to f/22, and offers a minimum focus distance of 10.2". Finally, a weather-sealed brass bayonet mount helps keep water and dust away from your equipment when shooting in rugged conditions.

  • Constant f/2.8 maximum aperture for working in low-light conditions, stops down to f/22.
  • Three Fluorite Low Dispersion (FLD), three Special Low Dispersion (SLD), and three aspherical elements in the design help reduce color fringing and chromatic aberrations for improved clarity.
  • A 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.
  • Front lens element has been treated with a water- and oil-repellent coating to benefit working in harsh environmental conditions.
  • Nine-blade rounded diaphragm contributes to a smooth and pleasing bokeh quality.
