Sigma has announced four lenses for Canon EF, Nikon F and Sigma SA mounts. Top of the list is a redesigned, stabilized 70-200mm F2.8. The 70-200mm F2.8 DG OIS is, as you'd expect, part of the company's Sport range of optics and is likely to offer a less-expensive alternative to OEM 70-200s. We will, of course, be testing its performance as soon as one becomes available.

The new 70-200mm F2.8 DG | S is slightly longer and noticeably heavier than the previous model: at 1805g it's gained 375g (13oz), but then it now features 24 elements in 22 groups, so there's a reason for that.
The lens's tripod plate has grooves to make it compatible with the Arca-Swiss standard.

Meanwhile, the 28mm F1.4 DG and 40mm F1.4 DG are both part of the company's premium 'Art' range that prioritize image quality over price and weight. These two lenses will also be available for the Sony E mount. The new lenses help round-out the series, which now includes a range of prime lenses extending from the 14mm F1.8 DG HSM up to the 135mm F1.8 DG.

The 28mm F1.4 DG adds a semi-wide option to Sigma's impressive range of 'Art' prime lenses.
The 28mm F1.4 DG | Art has a 77mm filter thread, matching that of the 24mm F1.4.
The 40mm F1.4 DG | Art is a near perfect 'normal' lens: a close match for the diagonal length of a full frame sensor. It's been a historically popular focal length, so we're pleased to see its return.
The Sigma 40mm F1.4 DG | Art has an 82mm filter thread.

Finally, Sigma has announced the 60-600mm F4.5-6.3 DG OIS, a monster telephoto lens, also part of its Sport range. Despite the sport designation, we suspect the lens will be used more for birding and airshow shooting.

The Sigma 60-600mm F4.5-6.3 DG | Sport is a substantial beast, even at its 60mm setting.
But that's nothing compared to seeing it at full stretch. It certainly lives up to the 'Bigma' nickname of its predecessor.

As you'd expect, it features a focus limiter, OIS control switch. In addition, there's a 'Custom mode switch' that can be used in conjunction with the Sigma USB Dock to access customized adjustments of the lens's focus and stabilizer behavior.

Sigma Unveils Five New Global Vision Lenses

Sigma’s 28mm F1.4 DG HSM Art, 40mm F1.4 DG HSM Art, 56mm F1.4 DC DN Contemporary, 70-200mm F2.8 DG OS HSM Sports, and 60-600mm F4.5-6.3 DG OS HSM Sports will make their public debut at Photokina 2018

Cologne, Germany – September 25, 2018 – Sigma today announced five new Sigma Global Vision lenses shown for the first time at the 2018 Photokina expo in Cologne, Germany from September 26th-29th in Hall 4.2 on Stands B020, B028I and C029. From wide-angle to hyper-telephoto, the new Sigma Global Vision introductions arrive as some of the most anticipated lenses in the industry, further facilitating artistic expression for photographers.

Sigma 28mm F1.4 DG HSM Art
The new Sigma wide-angle model stands out with its thoroughly corrected magnification chromatic aberration and sagittal coma flare, as well as completely minimized distortion thanks to its optical design. It features water- and oil-repellent coating on the front lens element and its overall dust- and splash-proof structure ensures excellent performance even in the most challenging shooting conditions. The high-speed AF, thanks to the HSM (Hyper Sonic Motor) with an updated algorithm, captures the perfect moment instantly. Available in Sigma, Nikon, Canon and Sony E camera mounts, this lens is a great contender for street photography, as well as shooting landscapes and night skies.

Sigma 40mm F1.4 DG HSM Art
The 40mm F1.4 DG HSM Art is Sigma’s first lens developed originally to live up to the sought-after angle of view and performance standard for a benchmark cine lens. This lens effectively arranges three FLD (“F” Low Dispersion) glass elements and three SLD (Special Low Dispersion) glass elements to correct axial chromatic aberration and magnification chromatic aberration. Designed for exceptional sharpness at maximum aperture, this lens excels at available light photography. With less than 1% distortion and near non-existent sagittal coma flare, this lens demonstrates consistent optical results featuring both 8K-compatible resolution and a beautiful bokeh. It is available for Sigma, Nikon, Canon and Sony E mount camera systems.

Sigma 56mm F1.4 DC DN Contemporary
This lens completes the Sigma large aperture series of portable wide-angle, standard, and telephoto prime lenses in Micro Four Thirds and Sony E mounts. Featuring compact design, light weight and outstanding image quality offered in Sigma’s Contemporary line, this lens stuns with a beautiful bokeh effect and the amount of brightness expected from F1.4 lenses even in the mid-telephoto range for cropped sensor cameras. In addition, this lens is characterized by smooth and quiet autofocus ideal for video shooting. Compatible with the Sony E mount Fast Hybrid AF, it also achieves precise AF tracking. By using the face recognition or eye AF functions of the camera, focus will continuously be on the face or the eye even if the subject moves during the shoot.

Sigma 70-200mm F2.8 DG OS HSM Sports
One of the most anticipated lenses from the Sigma Global Vision line, the Sigma 70-200mm F2.8 DG OS HSM Sports is the new flagship large-aperture telephoto zoom lens that meets the most stringent needs of professional photographers. Robust yet lightweight, the lens’ magnesium body ensures high mobility and its dust- and splash-proof structure together with the water- and oil-repellent coating on the front element ensure safe use even in the most challenging shooting conditions. It also incorporates Intelligent OS with an acceleration sensor and the latest algorithm capable of panning in all directions. The lens’ optical design, incorporating 10 exclusive low-dispersion glass elements, allows for extremely high resolution, from the center to the corners. By optimizing spherical aberration, a smooth and natural bokeh effect is achieved when using the Sigma 70-200mm F2.8 DG OS HSM Sports for portrait photography. The versatility of this lens is demonstrated in various customization options via an AF Function button either through the camera body or Sigma USB Dock. The newest F2.8 large-aperture zoom lens from Sigma comes in Sigma, Canon and Nikon mounts.

Sigma 60-600mm F4.5-6.3 DG OS HSM Sports
The Sigma 60-600mm F4.5-6.3 DG OS HSM Sports is the world’s first 10x optical zoom telephoto lens with a tele end of 600mm. Incorporating 25 elements in 19 groups, excellent and consistent image quality can be achieved throughout the entire zoom range. This lens’ intelligent OS featuring the latest algorithm delivers an image stabilization effect of 4 stops. Its optical design ensures maximum correction of magnification chromatic aberration encountered in hyper-telephoto shooting. This offers both high resolution and consistent edge-to-edge performance throughout the entire zoom range. In addition, when shooting at the focal length of 200mm, the Sigma 60-600mm F4.5-6.3 DG OS HSM Sports can also be used for telephoto macro photography, with a maximum magnification ratio of 1:3.3, thanks to its high rendering performance. Its multi-material build, which incorporates magnesium among other components, ensures durability and enhances portability, allowing for comfortable handling of the 10x zoom lens. The zooming mechanism has been engineered to make both smooth rotation and straight zoom possible. Versatile and robust, the new Sigma hyper-telephoto zoom lens is available in Sigma, Canon and Nikon mounts starting in late October 2018 for $1999 USD.
