Sigma announces full-frame 14-24mm F2.8 DG HSM Art lens

Sigma has announced a new 14-24mm F2.8 HSM Art lens for full-frame Canon, Nikon and Sigma DSLRs. This ultra-wide zoom has three FLD and three SLD glass elements, plus an 80mm 'high precision molded' aspherical element. The lens is sealed against dust and moisture and has a nine-blade aperture, minimum focus distance of 26cm (10") and a weight of around 1.2 kg (2.5 lb).

While the 14-24 comes with a petal-shaped hood, Sigma will offer a 'front mount conversion service' that will replace it with a circular hood, which is preferable when capturing content intended for VR use.

Living up to its Art designation, the 14-24mm has been designed with 50MP sensors in mind. It claims to minimize distortion to 1% or lower when focused to infinity, and the Canon mount version of the lens works with Canon's in-camera lens aberration correction. Each 14-24mm F2.8 comes from Sigma's Aizu, Japan factory.

Pricing and availability information will be released at a later date.

Press Release

Sigma Announces Brand New 14-24mm F2.8 Art Lens

February 9, 2018 - Sigma Corporation today announced the brand new 14-24mm F2.8 DG HSM Art wide aperture zoom lens. In addition to the new Global Vision full-frame lens model, Sigma also announced a new front conversion service for the 14-24mm F2.8.

Outstanding Art Lens Performance
Designed for 50-megapixel plus cameras, the 14-24mm F2.8 DG HSM Art achieves the legendary Art lens sharpness with three FLD glass elements, three SLD glass elements, and three aspherical lens elements, including one 80mm high precision molded glass aspherical element. With near zero distortion (less than 1%) and minimal transverse chromatic aberration, flare and ghosting, the new Sigma 14-24mm offers constant F2.8 brightness throughout the zoom range and delivers optimal image quality at every focal length and shooting distance. The high-speed, high-accuracy autofocus allows photographers to capture incredible, in-the-moment images.

Rugged Design
In addition to outstanding optical performance, the 14-24mm F2.8 DG HSM Art features the Sports line level dust- and splash-proof design with special sealing at the mount connection, manual focus ring, zoom ring and cover connection, allowing for the lens to be used during varying weather conditions.

Versatile Camera System Mount Support
The new Sigma 14-24mm F2.8 DG HSM Art lens supports Canon, Nikon and Sigma mounts and works with Sigma’s MC-11 Sony E-mount converter. The Nikon mount features brand new electromagnetic diaphragm, whereas the Canon mount is compatible with the Canon Lens Aberration Correction function.

Pricing and availability for the Sigma 14-24mm F2.8 Art lens will be announced later.

Front Mount Conversion Service for Sigma 14-24mm F2.8 DG HSM Art
Addressing the rising popularity of multi-camera productions, especially using ultra wide-angle lenses in shooting virtual reality (VR) content, Sigma has introduced its Front Conversion Service. Converting the petal-type hood of the 14-24mm F2.8 DG HSM Art to an exclusive round component allows for the lens to be used in various VR scenarios without the risk of interfering with other lenses in the VR rig or undesired shadows in the content.

The availability of this fee-based service for Sigma 14-24mm F2.8 Art will be announced at a later date.
