From Sigma:
 
Sigma Corporation Announces Pricing and Availability of 24-35mm F2 DG HSM Art Lens
 
Market’s first F2 full-frame zoom available in late July for $999
 
RONKONKOMA, NY — July 16, 2015 – Sigma Corporation of America, a leading DSLR lens and camera manufacturer, today announced that the new Sigma 24-35mm F2 DG HSM Art lens will become available in late July for the street price of $999.
 
The 24-35mm F2 DG HSM Art lens is the market’s first full-frame zoom that allows photographers to carry one fast aperture lens that can do the work of three popular fixed focal length lenses – the 24mm, 28mm and 35mm. It includes an optimized autofocus (AF) algorithm for smooth, fast, and accurate focusing, a manual focus (MF) override functionality, and is made of Thermally Stable Composite (TSC) reducing its size and weight.
 
Built upon the impressive versatility offered by Sigma’s 18-35mm F1.8 DC HSM Art lens, the new 24-35mm continues the Art line tradition of top optical performance that’s comparable to Sigma’s 24mm F1.4 DG HSM Art and 35mm F1.4 DG HSM Art. It offers optimized lens power distribution, and minimizes spherical aberration, axial chromatic aberration and field curvature. The Sigma 24-35mm F2 DG HSM Art lens also features a video-friendly, inner focusing system that eliminates front-lens rotation, enhancing the lens' stability as well as a Hyper Sonic Motor (HSM) that ensures a silent, high-speed AF function.
 
“The combination of fast, constant aperture and zoom versatility will make this lens exceptionally popular for photographers who crave the convenience of wide angle zooms, paired with the performance of fast, wide primes,” said Mark Amir-Hamzeh, president of Sigma Corporation of America. “The Art lenses have raised the bar for total imaging performance, and this lens is going to make a lot of photographers very happy.”
 
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. It 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.
 
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

Sigma 24-35mm f/2 DG HSM Art Lens
From Sigma:
 
The Sigma Corporation is pleased to announce that we are going to introduce the SIGMA 24-35mm F2 DG HSM | Art, the world's first large-aperture full-frame wide-angle zoom lens offering F2 brightness throughout the zoom range.
 
While offering the premier optics of the Art line, this lens covers 24mm, 28mm and 35mm focal lengths. Incredible performance overturns the conventional perception of a zoom lens.
 
SIGMA was determined to create a zoom lens that offers the same brightness and resolution as a fixed focal length lens: in other words, the highest level of optical performance. The result of this challenge was the SIGMA 18-35mm F1.8 DC HSM | Art, the world’s first zoom to offer a fast F1.8 aperture value throughout the zoom range. Building on this concept, SIGMA has developed the new SIGMA 24-35mm F2 DG HSM | Art for 35mm full frame sensor. It allows photographers to carry one lens to do the work of three fixed focal length lenses, a 24mm, 28mm and 35mm — with F2 brightness and top optical performance. One package delivers flexible functionality and high convenience. In particular, at the 24mm and 35mm focal lengths, this lens offers the performance that is equivalent to that of two prime lenses in the Art line. Instead of changing one high-performance fixed focal length lens for another, simply zoom. This is a new zoom lens for 35mm full frame sensor SLRs that offers the quality of a fixed focal length lens at various angles of view.
 
Key features
 
1. The world’s first large-aperture full-frame zoom lens offering a wide open aperture of F2 throughout the zoom range
A large-diameter zoom lens covering the full frame image sensor. Optical performance equivalent to a fixed focal length lens throughout the entire zoom range. These are the concepts the SIGMA 24-35mm F2 DG HSM embodies. It covers three of the most commonly used prime lenses, 24mm, 28mm and 35mm all in one lens. In order to achieve an attractive bokeh effect at wide aperture, we have developed the world's first zoom lens for the 35mm full frame sensor with an F2 aperture value throughout the zoom range.
 
2. Outstanding optical performance of the fixed focal length lenses in SIGMA’s Art line
The SIGMA 24-35mm F2 DG HSM builds on the concept of the SIGMA 18-35mm F1.8 DC HSM | Art, the world’s first zoom lens to offer F1.8 brightness throughout the zoom range. Thanks to the outstanding optical performance, the lens provides the quality of high performance fixed focal length lenses in the Art line
 
3. Covering the range of three fixed focal length wide-angle lenses
Delivering excellent functionality and convenience, one lens offers the equivalent quality of three high-performance fixed focal length lenses at F2 brightness: 24mm, 28mm and 35mm. With a minimum focusing distance of 28cm and a maximum magnification ratio of 1:4.4, this lens is suitable for close-up shooting, portraits with an attractive bokeh and deep-focus landscape photography. Photographers have access to the angle of view equivalent to that of three wide-angle lenses without having to switch them. While achieving the desired background effect can be difficult with a conventional wide-angle lens, the large diameter of this lens allows photographers to open the aperture wide and use the shallow focus to achieve stunning results.
 
4. Incorporating SIGMA’s latest technologies
To realize a large-diameter zoom lens for full frame cameras with F2 brightness, SIGMA designed each and every part with uncompromising care and quality. The lens incorporates large-diameter aspherical lens elements, which require advanced technologies to manufacture, one FLD (“F” Low Dispersion) glass and seven SLD (Special Low Dispersion) glass elements, of which two are aspherical lenses. The advanced optics and optimized lens power distribution minimize spherical aberration, axial chromatic aberration and field curvature, resulting in outstanding optical performance. Even at widest aperture, this lens delivers breathtaking image quality.
 
5. Convenient handling
The inner focusing system eliminates front lens rotation, enhancing the lens' stability and allowing use of Circular Polarizing filters. This specification is particularly convenient for shooting video.
 
Other features
 
Minimum focusing distance of 28cm
With a minimum focusing distance of 28cm and a maximum magnification ratio of 1:4.4, this lens is excellent for close-up photography.
 
Designed to minimize flare and ghosting
From an early stage in the lens design process, flare and ghosting have been measured to establish an optical design resistant to strong incident light sources such as backlighting. The Super Multi-Layer Coating reduces flare and ghosting and provides sharp and high contrast images even in backlit conditions. The included lens hood can be attached to block out extraneous light, which can have a negative effect on rendering performance.
 
Hyper Sonic Motor ensures High AF Speed
The HSM (Hyper Sonic Motor) ensures a silent, high-speed AF function. By optimizing the AF algorithm, smoother AF is achieved. Also, this lens offers full-time MF by rotating the focus ring of the lens while auto focusing. Without changing the AF/MF Focus Mode Switch, it allows faster focus adjustment.
 
Rounded Diaphragm
The 9 blade-rounded diaphragm creates an attractive blur to the out-of-focus areas of the image.
 
Brass bayonet mount
This lens incorporates a brass bayonet mount which has both high accuracy and durability. A special treatment to reinforce its strength is applied to the surface giving it greater strength and making it highly resistant to long-term use.
 
Applicable for the Mount Conversion Service
As an experienced lens manufacturer that has been creating a diverse range of interchangeable lenses, we have started the innovative "Mount Conversion Service". With this chargeable service, the mount of your current SIGMA lenses can be changed to another mount of your choice. It gives new life to your favorite lenses when you wish to use them on a different camera body.
 
Art line delivers high-level artistic expression
SIGMA is organizing all its interchangeable lenses into three product lines; Contemporary, Art, and Sports, where each line has a distinctive concept. Designed with a focus on sophisticated optical performance and abundant expressive power, our Art line delivers high-level artistic expression. With the astonishing rendering performance that meets the highest standard, along with landscapes, portraits, still-lifes, close-ups, and general snaps, they are perfect for the kind of photography that unleashes the inner artist. Ideal for studio photography, they offer just as much expressive scope when capturing architecture and starry skies and many other scenes.
 
Customization and flexible adjustment for convenience or a specific purpose is possible. SIGMA USB DOCK that is designed exclusively for the new lens line-ups.
With the optional SIGMA USB DOCK, you can update your lens firmware, adjust focus points and customize Full-time MF function settings as well as the timing to operate the Full-time MF function. By attaching this lens to a SIGMA USB DOCK, which is connected to a computer, the dedicated software "SIGMA Optimization Pro" offers various types of customization and adjustment.
 
New product lines from SGV concepts that are setting new benchmarks for image quality.
 
Design Concept
With the new product lines, supplied hoods incorporate rubber for the connected part. Lens caps and AF/MF switches are also newly designed in order to improve usability. For the internal parts, various metals and a new material called TSC (Thermally Stable Composite), which works well with metal, are located to achieve products with high accuracy. The lens barrel includes the year of release, engraved for users to recognize when the lens was released.
 
Evaluation with SIGMA's own MTF measuring system "A1"
We used to measure lens performance with an MTF measuring system using conventional sensors. However, we've now developed our own proprietary MTF (modulation transfer function) measuring system (A1) using 46-megapixel Foveon direct image sensors. Even previously undetectable high-frequency details are now within the scope of our quality control inspections. All SIGMA 24-35mm F2 DG HSM lenses will all be checked using "A1" before they are shipped.
 
Made in Japan
All SIGMA's manufacturing – right down to molds and parts – with a few exceptions, are carried out under a single integrated production system, entirely in Japan. We are now one of the very few manufacturers whose products are solely "made in Japan". We like to think our products are somehow imbued with the essence of our homeland, blessed as it is with clean air and water, and focused, hard-working people. We pride ourselves on the authentic quality of SIGMA products, born of a marriage between highly attuned expertise and intelligent, advanced technology. Our sophisticated products have satisfied professionals and lovers of photography all over the world, because our manufacturing is based on genuine craftsmanship, underpinned by the passion and pride of our experts.

Sigma 24mm f/1.4 DG HSM Art Lens
RONKONKOMA – April 9, 2015 – Sigma Corporation of America, a leading researcher, developer, manufacturer and service provider of some of the world's most impressive lines of lenses, cameras and flashes, is pleased to announce that the Technical Image Press Association (TIPA) has select two Sigma products for the TIPA Awards 2015. The 18-300mm F3.5-6.3 DC MACRO OS HSM Contemporary lens has been lauded Best Entry Level DSLR Lens, and the recently released 24mm F1.4 DG HSM Art lens won Best Expert DSLR Prime Lens.
 
With more than 25 years of experience in the industry, the TIPA organization has a worldwide membership of 27 photo and imaging magazines from 16 countries across five continents. When TIPA member magazines began the TIPA Awards, their goal was to develop an award that would showcase the best photography, imaging products and services introduced to the market during the past year. According to TIPA, only products that the General Assembly think deserve recognition are considered in the voting process.
 
“On behalf of Sigma Corporation, we are honored to have two Sigma lenses receive TIPA awards this year, and be recognized by such a far-reaching organization,” said Mark Amir-Hamzeh, president of Sigma Corporation of America. “We’re especially proud to be acknowledged as a company that continues to produce leading-edge technology in the photo industry. The addition of the 24mm F1.4 and 18-300mm F3.5-6.3 lenses to our Global Vision lineup demonstrates how Sigma is continuing to redefine expectations and improve the experience for our loyal users.”
 
As the ninth addition to Sigma’s iconic Global Vision Art line-up, the 24mm F1.4 DG HSM Art lens is designed for full-frame DSLRs, and when used on digital cameras with an APS-C size sensor, it effectively becomes a 38mm. The 24mm excels at indoor photography in low light, thanks to the combination of exceptional focal plane sharpness, and gorgeous bokeh rendered by nine rounded-aperture blades. The lens features both "F" Low Dispersion (FLD) glass and Special Low Dispersion (SLD) glass in a design of 15 elements in 11 groups to minimize chromatic aberration of magnification, especially at the edge of the image field. It also has the ability to achieve a maximum magnification of 1:5.3 with a minimum focusing distance of 9.8 inches.
 
The 18-300mm F3.5-6.3 DC MACRO OS HSM Contemporary lens is designed exclusively for APS-C camera sensors and features a 16.6x high-ratio zoom lens that equates to a 27-450mm zoom range. It incorporates four “F” Low Dispersion (FLD) glass elements, which have performance equal to fluorite, in addition to one Special Low Dispersion (SLD) glass element. This enables the lens to minimize the chromatic aberration, especially toward the telephoto-end, and provide clear image quality with high color fidelity. Also, this lens comes with a newly developed optical stabilization (OS) system, ensuring better compensation.
 
Both lenses are compatible with Sigma’s Mount Conversion Service and Sigma’s USB dock, allowing photographers to update the lens firmware and change focus parameters.

Sigma TS-81 Arca-Swiss Compatible Tripod Foot
From Sigma:
 
We are pleased to announce the development of TRIPOD SOCKET TS-81 that is the optional lens foot which can be attached to the SIGMA 150-600mm F5-6.3 DG OS HSM | Sports.
 
It is compatible with the Arca Swiss quick release plate and the clamp. The deliberately designed length of its rail provides the flexibility to adjust the center of gravity making it balance perfectly, even while zooming or using accessories, such as a tele converter and battery pack. Consideration has been given to the portability and transportation of the lens when Tripod Socket TS-81 is attached. The lens hood can still be reversed and the lens stored in its original padded case, even with the Tripod Socket TS-81 attached. Incorporated into the Tripod Socket are safety stopper screws to prevent the lens from falling. There are 2 sizes of screw holes, 1/4 and 3/8, making it compatible with tripods other than Arca Swiss, too. When it is compared to the supplied tripod socket, it offers more space between the lens and device, and the change of grip has improved the usage as a handle for carrying.
 
Launch Date & Price: TBD
 
Note: The TS-81 Tripod Foot is not yet available for preorder. We will advise when it becomes available.

Latest Global Vision Art lens offers highest-quality optical performance in its class
 
YOKOHAMA, Japan — February 10, 2015 – Sigma Corporation of America, a leading researcher, developer, manufacturer and service provider of some of the world's most impressive lines of lenses, cameras and flashes, today announced the new Sigma 24mm F1.4 DG HSM Art lens, the ninth Global Vision lens to join the company’s iconic Art line-up. The announcement comes at the start of the CP+ Camera and Photo Imaging Show 2015, which begins on Feb. 12 in Yokohama, Japan.
 
The much anticipated 24mm F1.4 Art wide angle lens is designed for full-frame DSLRs, and when used on digital cameras with an APS-C size image sensor, it effectively becomes a 38mm. The lens is ideal for capturing a variety of photography subjects, including cityscapes, mountain ranges, astrophotography and weddings and is great for videography work as well. The 24mm also excels at indoor photography in low illumination thanks to the combination of exceptional focal plane sharpness, and gorgeous bokeh rendered by nine rounded aperture blades. The lens achieves a maximum magnification of 1:5.3 with a minimum focusing distance of 9.8 inches. The 24mm incorporates both "F" Low Dispersion (FLD) glass and Special Low Dispersion (SLD) glass in a design of 15 elements in 11 groups to minimize chromatic aberration of magnification especially in the edge of the image field. Moreover, the optimized power layout includes aspherical elements that are positioned in the rear of the lens for improved wide open performance. This helps to ensure minimal distortion through the correction of axial chromatic aberration and sagittal coma flare. The new lens element design also delivers excellent peripheral brightness.
 
“The Sigma Art lenses are recognized by photographers for world-class performance, and the new 24mm F1.4 DG HSM will be a significant contribution to our selection of fast aperture prime lenses which is quickly becoming a strong force in the industry” said Mark Amir-Hamzeh, president of Sigma Corporation of America. “Sigma is redefining the expectations of fast-aperture full-frame prime lens performance, especially wide-open, and the results the 24mm F1.4 will deliver will be up to the exacting standards set by the 35mm F1.4 DG HSM and 50mm F1.4 DG HSM .”
 
Other updates to this lens include a new full-time manual focusing mechanism that switches to manual focusing, simply by rotating the focus ring, even when AF is being used, first introduced on the 50mm Art. This allows the photographer to make focus adjustments quickly and easily. As with all new lenses under the Global Vision categories, every 24mm will be tested using Sigma’s own 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, 19mm F2.8 DN, 30mm F2.8 DN and 60mm F2.8 DN.
 
The 24mm F1.4 is compatible with Sigma’s USB dock, allowing photographers to update the lens’ firmware and change focus parameters as well as manual focus over-ride using Sigma's Optimization Pro software. It is also compatible with Sigma’s Mount Conversion Service. The lens will be available in Canon, Nikon and Sigma mounts, and timing, pricing and availability will be announced at a later date.
 
Ordering the Sigma 24 Art Lens
 
Hopefully the fulfillment process for this lens is more expediant than we are currently experiencing with the 150-600 Sports and 24-105 Art lenses. While many lenses are introduced to relatively low demand, my expectation is that this is not one of them.
 
B&H has the Sigma 24mm f/1.4 DG HSM Art Lens in Canon, Nikon and Sigma mounts on their site, but preorders are not currently being accepted.
