Sigma Announces 24-35mm F2 DG HSM Art
Fastest full frame zoom in its class
By PF Staff in Photo Industry News on Jun 19, 2015
Sigma has just officially announced the latest member of its premium "Art" lens series: the 24-35mm F2 DG HSM. This short wide-angle zoom— designed for full frame cameras— offers a class-leading maximum aperture of F2. It is similar in concept to last year's Sigma 18-35mm F1.8 Art, which was designed exclusively for APS-C cameras.
The 18-35mm was the world's first APS-C DSLR zoom lens with an aperture faster than F2.8. The 24-35mm sets another record by being the first zoom with this kind of speed to cover the full frame image circle. Ever since Sigma revealed the Global Vision approach, the company appears to have been dedicated to standing out among its competitors by offering unique optical designs that are not available elsewhere. "There’s nothing like this lens on the market today; we’re thrilled to arm photographers with yet another unique, innovative and versatile lens that features the incredible image quality that has become the hallmark of our Art line," said Mark Amir-Hamzeh, president of the US branch of Sigma Corporation.
Focal lengths in the 24 to 35mm range are ideal for street shooting, landscapes, and astrophotography.
This lens will be available in Canon, Nikon, and Sigma mounts as early as July, 2015. No price information has yet been revealed. Sigma has made no official indication of plans to produce a Pentax K-mount variant of the lens, though it is possible that it will reconsider once the Pentax full frame DSLR starts shipping later this year.
Sigma is currently the only third-party lens manufacturer that offers recent autofocus lenses for Pentax cameras. The other manufacturer, Tamron, still sells several older designs. Both brands' products remain competitive with first-party offerings. Learn more about current Sigma lenses in our many in-depth reviews:

RONKONKOMA, N.Y.-- Sigma Corporation of America, a leading DSLR lens and camera manufacturer, today announced the Sigma 24-35mm F2 DG HSM Art lens, the market’s first full-frame zoom lens offering a wide-open, constant aperture of F2 throughout the zoom range. Pricing and availability are pending.
“There’s nothing like this lens on the market today; we’re thrilled to arm photographers with yet another unique, innovative and versatile lens that features the incredible image quality that has become the hallmark of our Art line.”
With the development of this latest Global Vision Art lens, Sigma was determined to develop a zoom for 35mm full-frame sensor cameras that enables the same sharpness and resolution as a fixed focal length lens. To do this, the company’s engineers built upon the concept of Sigma’s ground-breaking 18-35mm F1.8 DC HSM Art lens, which is designed for APS-C cameras and is the first zoom to offer a fast F1.8 aperture value throughout the zoom range. The 24-35mm F2 DG HSM Art allows photographers to carry one lens that can do the work of three popular fixed focal length lenses – the 24mm, 28mm and 35mm — with F2 brightness and top optical performance comparable to Sigma’s 24mm F1.4 DG HSM Art and 35mm F1.4 DG HSM Art.
“Now, rather than switching between three high-performance, fixed focal length lenses, photographers and videographers can simply zoom and know that the results will be of prime caliber,” said Mark Amir-Hamzeh, president of Sigma Corporation of America. “There’s nothing like this lens on the market today; we’re thrilled to arm photographers with yet another unique, innovative and versatile lens that features the incredible image quality that has become the hallmark of our Art line.”
The new 24-35mm lens incorporates the latest Sigma technology, including an optimized autofocus (AF) algorithm for smooth, fast, and accurate focusing, as well as manual focus (MF) override functionality. As with many Sigma Global Vision lenses, Thermally Stable Composite (TSC) compound material is used, which has a high affinity to metal parts, consistently performs well at extreme temperatures, and reduces the size and weight of the lens. In addition, its Super Multi-Layer Coating reduces flare and ghosting, and provides sharp and high-contrast images, even in backlit conditions. It’s ideal for close-up shooting, portraits and deep-focus landscape photography.
The Sigma 24-35mm F2 DG HSM Art lens will also feature:
- Large-diameter, aspherical lens elements, which require advanced technologies to produce, one “F” Low Dispersion (FLD) glass, and seven Special Low Dispersion (SLD) glass elements with two aspherical lenses. The advanced optics and optimized lens power distribution minimizes spherical aberration, axial chromatic aberration and field curvature, resulting in outstanding optical performance
- A video-friendly, inner focusing system that eliminates front-lens rotation, enhancing the lens' stability and allowing use of circular polarizing filters
- A Hyper Sonic Motor (HSM) that ensures a silent, high-speed AF function. Smoother AF is achieved when the this AF algorithm is optimized
- Full-time MF by rotating the focus ring of the lens while auto focusing
- A nine-blade, rounded diaphragm creates an attractive blur to the out-of-focus areas of the image
- Specifications: Lens construction containing 18 elements in 13 groups; a weight of 33.2 ounces; a diameter and length of 3.4 inches by 4.8 inches, respectively; a minimum aperture of F16; and angle of view (35mm) of 84.1° to 63.4°; minimum focusing distance of 11 inches; and a maximum magnification ratio of 1:4.4
This lens is compatible with Sigma’s USB DOCK, which allows photographers to update the lens’ firmware, adjust focus points and customize full-time MF function settings by using Sigma's Optimization Pro software. Sigma’s exclusive Mount Conversion Service, which enables users to easily convert the lens’ camera mount between supported versions, is also available for a fee. The lens will be available in Sigma, Canon and Nikon mounts. Timing, pricing and availability will be announced at a later date.
As with all new lenses under the Global Vision categories, every 24-35mm will be tested using Sigma’s own modulation transfer function (MTF) measuring system, “A1,” in the company’s factory in Japan. Other lenses in the Art line include: 35mm F1.4 DG HSM, 30mm F1.4 DC HSM, 18-35mm F1.8 DC HSM, 24-105mm F4 DG OS HSM, 50mm F1.4 DG HSM, 24mm F1.4 DG HSM, 19mm F2.8 DN, 30mm F2.8 DN and 60mm F2.8 DN.
