Utilising optical technology from Sigma’s Aizu factory,  the new lens includes three FLD glass elements, three SLD glass elements, and three aspherical lens elements, including one large-diameter aspherical element.  Effective distribution of these high-refractive-index glass elements further enhances the corrective effect of the FLD and SLD glass. This optical system minimizes transverse chromatic aberration and other optical aberrations, resulting in outstanding high-resolution image quality.

The new lens is dust- and splash-resistant, with special sealing at the mount connection, manual focus ring, zoom ring, and cover connection.  The front of the lens is protected by a water- and oil-repellent coating that makes cleaning easy.  The lens also supports high-speed, high-accuracy autofocusing along with full-time manual over-ride that  allows the lens to be switched to manual focus simply by rotating the focus ring. The 9-blade rounded diaphragm creates an attractive blur in the out-of-focus areas of the image.

Sigma claims the new lens will be free of distortion, while providing a constant maximum aperture of  f/2.8 throughout its zoom range. The design of the lens, plus Sigma’s Super Multi-Layer Coating, minimises flare and ghosting when shooting in strong incident light sources such as backlighting.  The supplied lens hood helps to block out extraneous light, which can have a negative effect on image rendering.

The new lens will be offered in mounts for Sigma, Nikon and Canon cameras. The Nikon mount version includes an electromagnetic diaphragm mechanism. The Canon mount lens is compatible with the Canon Lens Aberration Correction function.  Pricing and availability have yet to be announced.

Sigma has also announced a new Front Conversion Service which will allow the petal-type hood of the 14-24mm F2.8 DG HSM | Art lens to be modified to a round structure that will provide greater freedom in multi-camera VR videography. The new front also helps prevent the lens from interfering with other lenses or from casting a visible shadow. The use of this service has no impact on the validity of the product warranty. Charges will apply for conversion. For further information, visit  http://www.sigma-global.com/en/about/world-network/.
