The Sigma 12-24mm f/4.0 DG HSM Art lens is an ultra-wide-angle zoom lens that is perfectly suited for the era of high-resolution digital cameras. It delivers optimal image quality from the center to the edges, significantly minimizes distortion, and features an exceptionally low minimum focusing distance. With its impressive imaging performance, this lens is not only excellent for landscape photography, portraits, still life, close-ups, and snapshots, but it also opens up unprecedented creative perspectives for artistically ambitious photographers. The results are striking, whether capturing architecture, starry skies, or many other scenes. The use of SLD (Special Low Dispersion) and FLD glass elements ensures excellent correction of the most common optical errors throughout the entire zoom range. Ghosting is effectively suppressed thanks to the Super Multi-Layer (SML) coating. As a result, you get brilliant, color-neutral images.
