April 19, 2018 – The Sigma Corporation is pleased to announce it has won two TIPA World Awards 2018 for its wide-aperture ultra-wide-angle 14-24mm F2.8 DG HSM Art zoom lens and its large-diameter 24-70mm F2.8 DG OS HSM Art zoom lens suitable for any shoot.

TIPA’s Best DSLR Wide Angle Zoom Lens Award for Sigma 14-24mm F2.8 DG HSM Art:

A Perfect Match for Today’s High-Resolution Cameras

Mountable on Canon, Nikon and Sigma cameras, and compatible with the Sigma MC-11 Sony E-mount converter, the Sigma 14-24mm F2.8 DG HSM Art lens delivers a high level of sharpness with near zero distortion, along with high-speed and high-accuracy AF that matches up perfectly with today’s high-resolution cameras. The lens contains three FLD (“F” Low Dispersion) glass elements, three SLD (Super Low Dispersion) glass elements, and three aspherical lens elements, including an 80mm high precision molded glass aspherical element. It has special sealing at numerous points for dust- and splash-proof protection. Thoroughly modern, the Nikon mount features a brand new electromagnetic diaphragm; the Canon mount is compatible with the Canon Lens Aberration Correction function.

14mm

Center sharpness is high through from f/4 to f/11, with f/16 and f/22 being adversely affected by diffraction. The edges aren't quite as sharp as the center, with f/5.6-f/11 producing the sharpest results.

24mm

Centre sharpness is very good through from f/4 to f/11, with f/16 and f/22 being adversely affected by diffraction. The edges aren't quite as sharp as the center, with f/5.6-f/11 producing the sharpest results.

February 23, 2018 – Sigma Corporation of America, a leading still photo and cinema lens, camera, flash and accessory manufacturer, today announced that the latest addition to its Sigma Global Vision lens offerings, the 14-24mm F2.8 DG HSM Art, will be available in mid-March for $1,299.00 USD through authorized US retailers. 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 that set a new standard in the era of outstanding high-resolution.

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.

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.

Welcoming a new ultra-wide-angle lens to the Art line

Leveraging major manufacturing advances at the Aizu factory, SIGMA is now producing ultra-high-precision moulded glass aspherical lens elements as large as φ80mm and incorporating them in new products. This premier optical technology promises to set a new standard for excellence in ultra-wide-angle lenses.

For the Art line, SIGMA began development simultaneously of two ultra-wide-angle lenses offering the key focal length of 14mm: one prime, and one zoom. In 2017, the company launched the SIGMA 14mm F1.8 DG HSM | Art as the ultimate ultra-wide-angle prime lens. This lens offers outstanding image quality in combination with F1.8 brightness.

Now SIGMA is introducing the 14-24mm F2.8 DG HSM | Art as the ultimate ultra-wide-angle zoom. While minimising distortion, this lens offers outstanding F2.8 brightness throughout the zoom range and delivers top-level image quality at every focal length and every shooting distance. For these reasons, it is the definitive wide-aperture ultra-wide-angle zoom lens.

Key features

• Outstanding Art line image quality
• Compatible with Canon Lens Aberration Correction
• Professional specifications
• Introducing the new Front Conversion Service

Designed to team up with 50-megapixel-plus cameras and offer top-level optical performance throughout the zoom range, the 14-24mm F2.8 DG HSM | Art incorporates 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 minimises transverse chromatic aberration and other optical aberrations, resulting in outstanding high-resolution image quality.

The first element in the optical system is a large-diameter aspherical lens. Optimising the power distribution of this and the other lens elements minimises distortion to 1% or lower.* As a result, points of light appear as points without streaking from the centre of the image to the edge, and the light volume is also abundant throughout the frame. In addition, simulations performed from the design stage onward have helped minimise flare and ghosting. In combination, these technologies ensure excellent ultra-wide-angle performance.

At infinity focus

The Canon mount lens is compatible with the Canon Lens Aberration Correction function. Matching the optical characteristics of the lens, this function performs in-camera correction of peripheral illumination, chromatic aberrations, distortion and more, further enhancing image quality.

Like SIGMA's Sports line lenses, the 14-24mm F2.8 DG HSM | Art features a highly effective dust- and splash-proof structure with special sealing at the mount connection, manual focus ring, zoom ring, and cover connection, allowing photographers to work in all types of weather. In addition, the front of the lens is protected by a water- and oil-repellent coating that makes cleaning easy. The high-speed, high-accuracy autofocus helps photographers react in an instant to get those special shots.

Today's virtual reality creators favour multi-camera videography that leverages the capability of ultra-wide-angle lenses. Addressing this trend, SIGMA is offering the new Front Conversion Service, in which SIGMA converts the petal-type hood of the 14-24mm F2.8 DG HSM | Art lens to an exclusive round component. This altered front structure allows the lens to be deployed with 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.

Start of service: TBD
