Everything the photographer expects from an ultra-wide angle zoom - and even more.

A pioneer of ultra-wide angle zooms, SIGMA launched the first in 1979: the SIGMA ZOOM GAMMA 21-35mm F3.5-4. Since then, we have continued to create ultra-wide angular zooms, always incorporating the best of our technologies. In 2003, we introduced the SIGMA 12-24mm F4.5-5.6 EX DG, the first ultra wide-angle zoom lens for full-frame digital SLRs. In 2011, we launched a new, enhanced version, the SIGMA 12-24mm F4.5-5.6 II DG HSM. SIGMA 12-24mm F4.5-5.6 II DG HSM. It offered a wider angle of view than the human eye, allowing the user to enjoy a wide angle range with incredible perspectives. Today is the 3rd generation, the SIGMA 12-24mm F4 DG HSM | Art that perpetuates this tradition with high image quality and ergonomics at a new level.

The ultimate in ultra wide-angle performance

Today, SIGMA presents an ultra wide angle zoom perfect for the era of very high resolution cameras. The SIGMA 12-24mm F4 DG HSM | Art offers optimal image quality from the center to the corners, minimal distortion, and a small focus distance. To achieve this quality without compromise, SIGMA has used all its optical and technological expertise. Special materials such as low dispersion glasses play a key role, as does SIGMA's ability to manufacture a very large diameter aspherical lens.
Outstanding image quality - from the center to the edges of the image

Photographers expect from a wide-angle lens an image quality that is remarkable from the center to the edges, without any distortion. Such a performance is particularly appreciated in architectural photography. The new SIGMA 12-24mm F4 DG HSM | Art benefits from the expertise accumulated by SIGMA in the manufacture of aspherical lenses and incorporates several high precision molded aspherical lenses. It also features an FLD ("F" Low Dispersion) glass element that performs as well as fluorite, all in an optimized optical design that minimizes distortion, transverse chromatic aberration, and flare. coma. The result is a stunning image quality on the entire frame.
