The Sigma 12-24mm f/4 Art is Sigma's first ultra-wide-angle zoom in the Art series. Dust- and splash-resistant, the Sigma takes on competitors like Canon's 11-24mm f/4 lens. The lens is built to fit today's high-resolution cameras, with a focus on optical performance.
The lens has 16 lens elements in 11 groups and the optical design of aspherical glass and FLD (F Low Dispersion) glass elements provides very good image quality; both aberration and distortion are reduced from the center of the image to the edges.
