Sigma Art 14-24mm 2.8 DG HSM für Nikon F

The Sigma 14-24mm F2.8 DG HSM Art is a new ultra-wide-angle zoom lens for full-frame and APS-C Canon, Nikon and Sigma DSLR cameras with a constant maximum aperture of f/2.8 available throughout the zoom range. It offers the equivalent angle of view as a 21-36 mm lens on an APS-C system (depending on the exact crop factor). The Sigma 14-24mm F2.8 DG HSM Art is comprised of 17 elements in 11 groups including three Fluorite Low Dispersion (FLD), three Special Low Dispersion (SLD), and three aspherical elements, including one 80mm high precision molded glass aspherical element, and it features a rounded 9 blade diaphragm which creates an attractive blur to the out of focus areas of the image. It has a minimum focusing distance of 26cm / 10.24in and a maximum reproduction ratio of 1:5.4, silent high-speed AF performance, full-time manual focusing, enhanced weather-proof construction, and Sigma's Super Multi-Layer Coating to reduce flare and ghosting. The Sigma 14-24mm F2.8 DG HSM Art lens retails for £1399 / $1299 in the UK and the US, respectively.

The Sigma 14-24mm f2.8 Art is one of the best ultra-wide angle zoom lenses for Canon and Nikon DSLRs, and is also an option for Sony mirrorless owners via an adapter. It can produce very sharp and undistorted images but you have to stop down on the short end to reduce the effect of astigmatism and field curvature (at least on my copy). It comes with the option to adapt the lens to different mounts plus it has a very thorough weather sealing. It is large and heavy and does not offer a filter thread but that is par for the course with all ultra-wide large aperture zooms. Highly Recommended.
