Sigma 14-24mm F2.8 DG HSM Art

Manufacturer description: The Sigma 14-24mm F2.8 Art is a full-frame ultrawide zoom lens that will be available for Canon, Nikon and Sigma mounts, as well as offering full compatibility with Sigma's MC-11 adapter for Sony E-mount. Being an Art lens, the 14-24mm F2.8 is designed to a very high standard, featuring low distortion, an array of specialty lens elements, and it should exhibit great sharpness for cameras with 50 megapixels and up. The 14-24mm F2.8 also comes with splash and dust sealing, and Sigma has made available a front-mount conversion service, to swap the petal-style hood to a round one for better compatibility with VR setups.
