At $1,299, the Sigma 14-24mm f/2.8 DG HSM Art lens is about $600 cheaper than the Nikon 14-24mm f/2.8G and $700 cheaper than Canon's similar 16-35mm f/2.8L III. Meanwhile, it's also specifically designed for high-resolution, 50-megapixel cameras and features similar professional weather-proofing features as its competitors' high-end, wide-angle zooms. Both the Nikon and Canon versions feature the latest lens technologies respectively supported by each brand, such as Nikon's electromagnetic diaphragm and Canon's Lens Aberration Correction function. Additionally, the new Sigma lens will be available in the Sigma SA mount.
The new Sigma lens also focuses a full inch closer than its competitors' lenses at a minimum focusing distance of 10.2 inches compared to 11 inches. However, it is also 10- to 30-percent heavier than its counterparts with more elements than either, including three fluorite low dispersion, three special low dispersion, and three aspherical elements in its design. All of these lenses feature nine-bladed, rounded apertures.
