The first and fastest of its kind Truly a revolutionary product, the Sigma 18-35mm 1.8 DC HSM is the first wide-angle to standard zoom lens to achieve a large aperture of 1.8. Designed specifically for APS-C sized sensors, the Sigma 18-35mm 1.8 translates to 27mm-52.5mm on 35mm camera. With a continuous speed of F1.8, Sigma is currently developing the fastest zoom lens for APS-C cameras with the Sigma 18-35. The focal length range should range from 18-35 millimeters, which corresponds to a 35mm equivalent of 27-53 millimeters for APS-C sensors.

Sigma issued an update to their previous press release on their lenses compatibility with the Nikon Z7 mirrorless camera (see also Tamron’s and Tokina’s compatibility notices):

Thank you for purchasing and using our products.

We would like to share results of our further investigations regarding the operating conditions of the Nikon “Z7” and SIGMA’s interchangeable lenses for Nikon mount.

When SIGMA’s interchangeable lenses in the current product lineup, listed below, are used in combination with the Nikon “Z7” and their “Mount Adapter FTZ”, both AF and AE operate without any issues.
Furthermore, lenses which incorporate Optical Stabilizer (OS) will work to maximum effect when both the lens’s OS and the in-camera stabilization are switched on simultaneously.

Phenomena particular to 4 lenses were confirmed after our announcement of September 28th

Firmware Sigma 18 35mm F/4

After careful investigation, we confirmed some phenomena particular to 4 products listed below.
Regarding a firmware update for the SIGMA 24-35mm F2 DG HSM Art, 50mm F1.4 DG HSM Art and 85mm F1.4 DG HSM Art, we are going to announce them at a later date.

■ 24-35mm F2 DG HSM Art
[Phenomenon]
It may occasionally stop recording while shooting video.
[Future Course of Action]
It is planned to be resolved by a firmware update.

■ 50mm F1.4 DG HSM Art
[Phenomenon]
When starting to shoot with the subject completely out of focus, the response to the AF operation is intermittent. It is necessary to release several times or to turn the focus ring once to release.
[Future Course of Action]
It is planned to be resolved by a firmware update.

■ 85mm F1.4 DG HSM Art
[Phenomenon]
It may occasionally show overexposure when narrowing down the aperture from F5.6 while shooting.
[Future Course of Action]
It is planned to be resolved by a firmware update.

■ APO 800mm F5.6 EX DG HSM
[Phenomenon]
Please focus using MF, since it is difficult to achieve sufficient focusing accuracy.
[Future Course of Action]
There is no plan for a firmware update.

When the lenses listed below are used, due to product specifications, the in-camera stabilization cannot be turned off. In addition, the Auto Power Off function cannot be used. Please manually turn the power [OFF] after shooting.

(From Sigma lens literature) Sigma Corporation of America, a leading researcher, developer, manufacturer and service provider for some of the world's most impressive lines of lenses, cameras and flashes, has announced the Sigma 18-35mm F1.8 DC HSM Art lens, the market’s first zoom lens to achieve a maximum aperture F1.8 throughout the entire zoom range.

This revolutionary, wide aperture, standard zoom lens is created for DSLR cameras with APS-C size sensors, which translates to a focal range of 27-52.5mm on a 35mm camera. With a minimum focusing distance of 11 inches, and a maximum magnification ratio of 1:4.3, the 18-35mm is ideal for landscapes, portraits, still-life, studio, close-up and casual photography.

“Exceptionally fast apertures were previously unavailable in zoom lenses, so photographers turned to several prime lenses in a session to get bright images at various focal lengths. We’re incredibly excited to be the first manufacturer to bring the F1.8 standard zoom to the market and to provide photographers with a new level of creativity and convenience, with the outstanding image quality at the core of the new Sigma Global Vision,” said Mark Amir-Hamzeh, president of Sigma Corporation of America.

Amir-Hamzeh added that because developing a large aperture wide angle zoom lens can prove to be technologically and optically challenging, often resulting in various distortions, aberrations and field curvature, Sigma has tapped into its long history as a lens pioneer to overcome those issues in this new generation lens.

“Our experience with the wide angle designs of our 12-24mm F4.5-5.6 II DG HSM and our 8-16mm F4.5-5.6 DC HSM, and our research and development in our Aizu factory have prepared us for this technological advancement,” he said. “Our wide, glass-molded aspherical lens and the incorporation of Special Low Dispersion (SLD) glass have optimized power distribution of the optical elements and compensated for various aberrations, as well as curvature of field at the widest angle. We’re extremely proud of this achievement.”

The 18-35mm is the latest addition to the company’s Art line of lenses, designed under the new Global Vision. The Global Vision lenses have a sleek new design with the manufacturing year stamped on the barrel, and are categorized by use into one of three groups: Art, Contemporary and Sports. The Art category delivers high-level artistic expression through sophisticated and abundant expressive power.

The new 18-35mm lens incorporates Sigma’s improved AF/MF switch and the use of Thermally Stable Composite (TSC) compound material, which has a high affinity to metal parts, consistently performs well at extreme temperatures, and reduces the size and weight of the lens. It is also compatible with Sigma’s new USB Dock, which will be available in coming months, enabling photographers to update lens firmware and adjust focus parameters from their computers.

Convenient handling is achieved with internal focusing and zooming, which prevents changes to the size of the lens. Additionally, the front part of the lens does not rotate, so special filters like circular polarizers can be used.

The 18-35mm lens’ Super Multi-Layer Coating reduces flare and ghosting and provides sharp and high contrast images, even in backlit conditions. The petal-type hood that is supplied with the lens will provide extra protection from flare and ghosting. Sigma’s Hyper Sonic Motor (HSM) ensures a silent, high-speed AF function and the optimized auto focus algorithm results in smooth focusing and full-time manual focusing capability. Lastly, the nine-blade, rounded diaphragm creates an attractive, round bokeh at large-aperture settings.
