Sigma has introduced a new ultra-wide-angle zoom lens for the ART series, which offers a maximum aperture of F2.8 over the entire focal length range of 14-24mm (full-format) and is supposed to reproduce the image without distortion. Thanks to new manufacturing techniques, Sigma is able to produce aspherical lenses from precision-blank pressed glass with a large diameter (up to 80mm) -- one of the first elements (of 17 in 11 groups) to be built into this lens, which, according to the manufacturer, is primarily responsible for the optimized image quality.
The zoom lens is protected against dust and splash water and measures 96.4mm (diameter) x 135.1mm at a weight of 1,150g. The close-up limit is 26 to 28 cm, the aperture consists of nine lamellas. The Sigma 14-24mm F2.8 DG HSM | Art will be released for Canon EF, Nikon F (FX), Sigma SA and will be compatible with Sigma´s MC-11 Sony E-Mount converter. When and at what price is still open.
Keep in mind that the ART series is designed for photography; the lens is not stabilized and the ultrasonic motor (HSM) works "almost silent". However, Sigma explicitly offers a new front-change service for multi-camera VR videography -- the tulip-shaped lens hood is replaced by a round component, so that nothing juts into the picture during a 360° setup.
