Sigma has released Firmware v 1.02 for the 18-35mm f/1.8 DC HSM
Autofocus is supported at any aperture value when used with the Canon Digital Cinema Camera EOS C100.
Please Note: Before upgrading the firmware of 18-35mm F1.8 DC HSM A013, please first update your SIGMA Optimization Pro to Ver1.2.0.

B&H Photo has notified us that they once against have limited stock of two new highly sought after Sigma lenses.
Both lenses are still only available in limited numbers.

Bryan at TDP has completed his review of the highly anticipated Sigma 18-35mm f/1.8 DC HSM Art lens. His only knocks against it are the lack of OS (which isn’t a huge deal) and the limited range on APS-C. However, the uniqueness and performance of this lens should overcome both of those negatives if you’re looking for something in that range.
“It is easy to overlook any focal length range deficiencies when getting an f/1.8 max aperture available over the entire focal length range. Not only is this the widest aperture zoom lens, but it is also the widest aperture 18mm lens. Full frame sensor camera owners have typically enjoyed about 1 stop of high ISO noise benefit and background blurring capability over APS-C/1.5x/1.6x format sensor camera owners. But, full frame camera owners do not have a zoom lens wider than f/2.8 available to them. The Sigma 18-35mm f/1.8 DC HSM “Art” Lens is a bit of an equalizer in this comparison.”‘

More magic from Sigma coming?
The last year or two from Sigma has been a pretty good one. A lot of highly regarded lenses have been released that come in at pretty great prices compared to the competitors.
We’re told Sigma is working on a 24-70 f/2 OS HSM for full frame cameras. We’re told they want to give a full frame zoom option faster than f/2.8 that rivals the APS-C 18-35 f/1.8 DC HSM. There was no word on what pricing would be, but it would definitely come in under the Canon EF 24-74 f/2.8L II.
We’re told this could be a Photokina 2014 lens. Next year is going to be a big one for Canon & Sigma by all indications.
From DXO Mark
The folks at DXOMark have tested the new Sigma 18-35 f/1.8 DC (APS-C) HSM lens and found to be extremely sharp. It turns out that it’s the sharpest APS-C lens that they have ever tested. The performance rivals that of Canon’s 24-70 f/2.8L II lens.
“Although it is unlikely a user would buy several full-frame wide-angle lenses specifically for an APS-C format camera, the fact remains that the Sigma 18-35mm f/1.8 DC HSM is an outstanding performer optically.
If we want to be picky, the Sigma lacks image stabilization and the zoom range isn’t as wide as some rivals, but at $799 the lens is remarkable….”

RONKONKOMA, NY, Apr. 18, 2013 — Sigma Corporation of America (www.sigmaphoto.com), a leading researcher, developer, manufacturer and service provider for some of the world’s most impressive lines of lenses, cameras and flashes, today 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 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.
