Featuring lens elements made with "F" Low Dispersion glass to minimise distortion, chromatic aberration, and flare, the Sigma 12-24mm f4 Art DG HSM Lens has a design that guarantees outstanding image quality from the centre to the edges of images. This super-wide-angle zoom lens is the 3rd-generation 12-24mm lens from Sigma. Its constant f4 aperture makes it 1-stop brighter than similar lenses.
