Sigma 14-24mm f/2.8 Art DG HSM Art lens, Nikon F

Sigma 14-24mm F2.8 A DG HSM Art ultra-wide-angle lens

The Sigma 14-24mm F2.8 A DG HSM Art is a continuous f/2.8 aperture lens from Sigma. It's a stunning option for those shooting landscapes or architecture. The lens is part of the prestigious Art series, which is finely designed with FLD, SLD and aspherical elements to minimise chromatic aberrations and keep distortion at bay. Super Multi-Layer coating on the lens surface keeps reflections and haze at bay, resulting in images that are colourful and contrasty.

In addition to the photographic delights, the Sigma 14-24mm F2.8 A DG HSM Art lens also has technology worth mentioning. The lens features a Hyper Sonic motor that ensures fast and quiet autofocus operation with full-time manual override. The lens has a rounded 9-blade aperture for smooth bokeh. It closes at f/22 and has a shortest focusing distance of 26 cm. And as the cherry on the cake, a weatherproof brass mount keeps water and dust out when shooting in harsh conditions.

The Sigma 14-24mm f/2.8 Art DG HSM cannot be fitted with standard filters because the front element protrudes from the lens body. However, there is a solution to this problem, namely NiSi has manufactured an external filter-clip for this particular lens. The lens is also compatible with Sigma USB dock to update the lens firmware and fine-tune its features.
