Sigma 18-35mm f/1.8 DC HSM Lens
From Sigma:
 
RONKONKOMA, N.Y., — June 14, 2013 — 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 that its new Sigma 18-35mm F1.8 DC HSM Art lens will arrive in the United States early July for the street price of $799.
 
As the market’s first zoom lens to achieve a maximum aperture of F1.8 throughout the entire zoom range, the 18-35mm was created for DSLR cameras with APS-C size sensors, which translates to a focal range of 27-52.5mm on a 35mm camera. This lens will be available early July in Sigma and Canon mounts, with Nikon, Sony and Pentax mounts to follow.
 
“Sigma users are really excited about this lens. They’ve been watching the new Art line very closely – and their reaction to our initial announcement of this lens has been fantastic,” said Mark Amir-Hamzeh, president of Sigma Corporation of America. “More than 50 years of innovating with photography equipment has helped us build new generation lenses like the 18-35mm F1.8. We’re confident that photographers who focus on landscape, portrait, still-life, studio, close-up and casual shots will love this lens.”
 
The 18-35mm F1.8 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 F1.8 lens features 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. The lens’ Super Multi-Layer Coating reduces flare and ghosting and provides sharp and high contrast images, even in backlit conditions. Sigma’s Hyper Sonic Motor (HSM) ensures a silent, high-speed AF function, while its nine-blade, rounded diaphragm creates an attractive, round bokeh at large-aperture settings.
 
The 18-35mm F1.8 lens is also compatible with Sigma’s new USB Dock, which is available for the street price of $59, enabling photographers to update lens firmware and adjust focus parameters from their computers.

Sigma 120-300mm f/2.8-4 DG OS HSM Lens
From Sigma:
 
Global Vision products hit shelves in US early May
 
RONKONKOMA, N.Y., — April 24, 2013 — 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 pricing and availability of the Sigma USB dock and the company’s newly redesigned 120-300mm F2.8 DG OS HSM from the Global Vision Sport lens category.
 
The updated 120-300mm F2.8 DG OS HSM lens will be available in early May for the street price of $3,599 in Sigma and Canon mounts. The USB dock, which is compatible with lenses from Sigma’s new Global Vision lineup, will also be available in early May for the street price of $59.
 
“As the first lens of our Sports lineup to become available, we’re glad to continue the next round of our Global Vision lenses with the 120-300mm F2.8,” said Mark Amir-Hamzeh, president of Sigma Corporation of America. “Our USB dock is the first in the industry of its kind, and we’re confident that it will be a ground-breaking product in helping photographers as they work.”
 
With redesigned mechanics and performance, this Sports lens is an update from its predecessor released in February 2011. With a maximum focal length of 300mm and a wide-open aperture of F2.8, this lens eases difficult shooting conditions. It is dust and moisture resistant, and allows users to switch between two custom settings created via the USB dock. The 120-300mm lens has been redesigned and quality-control tested with Sigma’s proprietary modulation transfer function (MTF) “A1” measuring system as part of Sigma’s new Global Vision category restructuring. Under the new Sports category, the lens also has the manufacturing year stamped on the barrel.
 
The Sigma USB dock, an industry first, works in conjunction with Sigma Optimization Pro (SOP) software to connect a photographer’s lens to their personal computer and the internet to update firmware and other parameters. The AF speed, focus limiter and OS function are also customizable for Sports lenses, such as the 120-300mm F2.8 DG OS HSM. Upon arrival of the products, SOP will be available via a downloadable copy online here. A video demonstration of SOP software is available here.

Sigma 18-35mm F1.8 DC HSM Len
From Sigma:
 
Sigma Corporation announces world's first F1.8 constant aperture zoom lens
 
New 18-35mm F1.8 DC HSM features Global Vision Art lens design
 
RONKONKOMA, NY — 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 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.

Sigma 17-70mm f/2.8-4 DC Macro OS HSM
 
From Sigma:
 
The Sigma Corporation is pleased to announce the release of the new SIGMA 17-70mm F2.8-4 DC MACRO OS HSM / DC MACRO HSM, the large-aperture APS-C standard zoom lens with a focal range that covers all your everyday needs along with macro functionality.
 
The most important features for a standard zoom lens for digital single lens reflex camera is to achieve high image quality, to meet the needs in various occasions and to be handy and compact.
 
The SIGMA 17-70mm F2.8-4 DC MACRO OS HSM will clear away all the general concerns, such as a short minimum focusing distance, not a long enough focal length for telephoto shooting and a small aperture value. Mainly used for general-purpose photography, this everyday lens covers a range equivalent to 25.5-105mm on a 35mm camera. It’s surprisingly compact in size for a large-aperture lens that opens up to F2.8. Great for treasured snapshots of travel or family occasions, it also handles shots that are a little bit more creative. Designed to be the kind of lens you carry around with you all the time, it delivers simplicity and is so user-friendly it’s sure to satisfy even the most demanding of users.
 
Special Features:

  1. Contemporary line can handle all sorts of photo opportunities
    Sigma is organizing all its interchangeable lenses into three product lines; Contemporary, Art and Sports. Featuring the very latest technology, and combining optical performance with compactness, the Contemporary line covers a wide range of needs. Incorporating the very latest technology in these lenses, Sigma has solved the difficult problem of keeping size and weight low without compromising optical performance. The SIGMA 17-70mm F2.8-4 DC MACRO OS HSM is the first product from the Contemporary line. Featuring a wide zoom range, the lens has a focal range equivalent to 25.5-105mm on a 35mm lens.
  2. Excellent for macro photography
    This lens’ minimum focusing distance is 22cm and the maximum magnification ratio is 1:2.8. At 70mm, the working distance becomes 5.52cm. When it comes to telephoto, it can shoot pictures with a similar sensation to a macro lens. Also, without the need to change the lens, it enables photographers to take a close up pictures of subjects such as jewelry and flowers. In order to secure a clear field of view, the design of this lens is very thorough, even down to the precise position of the engraved letters on the lens.
  3. 30% Smaller Than Conventional Models
    For a which is used lens used in everyday situations, the small size makes a big difference. By incorporating a smaller OS unit and optimizing the structure and power distribution of optical elements, the lens barrel has now become more compact. In order to ensure high accuracy of the product, the new compound material TSC (Thermally Stable Composite), which has high affinity to metal parts, is introduced for the lens barrel. It results in better durability of the parts and smaller zoom rings and scale rings. The dimension of this lens is 30% smaller than our conventional models.
  4. Superior Image Quality Throughout The Entire Zoom Range
    This lens incorporates 2 FLD (“F” Low Dispersion) glass elements, which have performance equal to fluorite, 1 SLD (Special Low Dispersion) glass element and 3 aspherical glass lenses including double sided aspherical lens. By optimizing the power alignment of the lens, both chromatic aberration of magnification and axial chromatic aberration have been corrected. From infinity to macro, it achieves superior image quality through entire zoom range. This lens offers extraordinary expressive power and is capable of surpassing the requirement of the rigorous checking process of our new MTF measuring system “A1”.
  5. Large maximum aperture of F2.8
    The aperture value is F2.8 at the wide end (17mm), and is F4 at the telephoto end (70mm). The bright viewfinder aids focusing and composition of images. The fast apertures also offer useful functions such as fast shutter speeds to prevent an object from being blurred and ensuring a smooth bokeh in the background.

Other Features:

  • Optical Stabilizer - Sigma’s own unique OS (Optical Stabilizer) function is incorporated. It offers effective correction of approximately 4 stops, which makes it possible to compensate for camera shake even in macro range photography where a small blur can be easily identified.
     
    *1. The closer the lens is to the object, the less effective the OS function is.
    *2. For Sony and Pentax, OS function is not incorporated.
  • Flare and ghosting conscious design - In order to achieve high rendering on this flagship lens, flare and ghosting were thoroughly measured from an early stage to establish an optical design which is resistant to strong incident light such as backlight. The Super Multi-Layer Coating reduces flare and ghosting and provides sharp and high contrast images even in backlit conditions.
  • Incorporating Rounded Diaphragm - The 7 blade-rounded diaphragm creates an attractive blur to the out-of-focus areas of the image.
  • Hyper Sonic Motor - The HSM (Hyper Sonic Motor) ensures high speed and quiet AF as well as full-time manual focus override by rotation of the focus ring. With the enhanced AF algorithm, smoother AF is achieved.
  • Brass made bayonet mount This lens incorporates a brass made 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.
  • Ease of use - The new product lines incorporate rubber for the attachment part of the provided lens hood. For better usability, the design of the lens cap and AF / MF changeover switch has been improved.
  • Newly developed “USB DOCK” exclusively for new product lines - Based on these new lines, we have developed special software (SIGMA Optimization Pro) that can update the lens firmware and adjust parameters such as focus.
  • Evaluation with Sigma’s own MTF measuring system “A1” - We used to measure lens performance with 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. The SIGMA 17-70mm F2.8-4 DC MACRO OS HSM will all be checked using this “A1” before they are shipped.
  • “Made in Japan” - All Sigma's manufacturing – right down to molds and parts – is carried out under an 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 120-300mm f/2.8-4 DG OS HSM
 
From Sigma:
 
The Sigma Corporation is pleased to announce the release of the new SIGMA 120-300mm F2.8 DG OS HSM, the telephoto zoom lens that achieves superior performance redesigned to meet photographers' needs.
 
Conventionally, large aperture lenses for 300mm F2.8 have been loved by professional users due to their brilliant capability of depiction and bright aperture value. It has established a solid standpoint in the world of photography. Based on the concept that turning a 300mm F2.8 lens into zoom lens would enable photographers to expand the scope of shooting, we have developed 120-300mm F2.8 lenses and released them into the market. It is not simple to decide on a composition with a 300mm lens. Especially for sports and theatrical shows, shooting positions are almost always fixed and changing lenses could lead to missed photographs. By adding a zoom function with the large aperture 300mm F2.8 lens, it no longer requires other interchangeable lenses and rotation of the zoom ring will offer excellent framing. In other words, when conditions are difficult, this high-performance lens gives you more scope to express yourself in the shots you take.
 
Special Features:

  1. Sports line lenses deliver high action-capture performance
    Sigma is organizing all its interchangeable lenses into three product lines; Contemporary, Art and Sports. While offering sophisticated optical performance and expressiveness, our Sports line lenses deliver high action-capture performance, enabling photographers to get exactly the shots they want. With their high-level optical performance and expressive power, these lenses can capture fast-moving subjects, even at distance. This high-performance line also offers a variety of functions to aid the photographer in challenging conditions and scenarios. The SIGMA 120-300mm F2.8 DG OS HSM is the first product from the “Sports” line. Besides sports photography, the lenses are also perfect for nature shots featuring birds, wild animals and other wildlife, and for capture of aircraft, trains, racing cars and more. Another major feature of our Sports line lenses is their wide range of customization functions: using the software provided, all sorts of settings can be tailored to the personal preferences of the photographer.
  2. Dust-proof and splash-proof construction
    For professional purposes, we have achieved excellent durability by incorporating dust-proof and splash-proof parts for joint parts, such as mount attachment, manual ring, zoom-ring, switches for customization and external switch panels. It prevents dust and dirt from entering the lens. Also, the usage of the zoom ring and focus ring is well positioned for shooting situations.
  3. High image quality close to fixed focal length lens.
    This lens incorporates 2 FLD (“F” Low Dispersion) glass elements, which have performance equal to fluorite, 1 SLD (Special Low Dispersion) glass element, and compensate for the color aberration at the utmost. The design also compensates for sagittal coma flare and minimizes the blurring of a point light source in peripheral areas. It offers very high image quality, close to fixed focal length lens.
  4. Incorporation of focus limiter
    Excellent usability is achieved by incorporating inner focusing and zooming that requires no change in the length of the lens for focus and zoom. It is possible to use with a rounded filter, such as a Circular Polarizer, as the front part of the lens is fixed. Due to the focus limiter offering adjustable range of auto focusing, this lens can provide fast focus setting. The USB dock enables users to change the range of the auto focusing at the discretion of users' creativity.
  5. Newly developed “USB DOCK” exclusively for new product lines
    Based on these new lines, we have developed special software (SIGMA Optimization Pro) that can update the lens firmware and adjust parameters such as focus. In addition, the lenses from our Sports line have customizable AF speed, focus limiter and OS function. The “Custom Mode Switch” is the device for further customization on the dedicated lenses.
  6. Ease of use
    Many parts of this lens have been designed for comfortable usage. For example, the design of the zoom ring is concerned with a texture when you hold it, the position of printed letters and the 4 control switches with integration-considered shape of the screws. Included accessories such as the removable lens hood and the newly designed tripod collar with strap ensure added ease of use.

Other Features:

  • Flare and ghosting conscious design - SIGMA’s Super Multi-Layer Coating reduces flare and ghosting. It provides sharp and high contrast images throughout the entire zoom range.
  • Excellent in handheld photography for telephoto shooting - This lens incorporates the OS system which offers the use of shutter speeds approximately 4 stops slower than would otherwise be possible, ensuring the excellent use in handheld photography for telephoto shooting. The OS system has two modes - OS mode 1 is suitable for general photography, and OS mode 2 is best for panning shots of subjects such as planes or racing cars. It is possible to adjust the OS using the optional USB DOCK.
     
    * This lens cannot be used with film SLR cameras with the exception of the Nikon F6, Canon EOS-1v.
  • Quiet and Fast AF - The HSM (Hyper Sonic Motor) ensures high speed and quiet AF as well as full-time manual focus override by rotation of the focus ring. With the enhanced AF algorithm, smoother AF is achieved. The full time manual, which offers further adjustment after focusing with AF mode, is possible. By using USB Dock, you can change and adjust the AF speed at your convenience.
  • Incorporating Rounded Diaphragm - The 9 blade-rounded diaphragm creates an attractive blur to the out-of-focus areas of the image.
  • APO Tele-Converter (Optional) - The addition of Sigma's 1.4x EX DG APO or 2x EX DG APO TELE CONVERTER produces a 168-420mm F4 AF telephoto zoom lens or a 240-600mm F5.6 AF telephoto zoom lens respectively.
  • Brass made bayonet mount - This lens incorporates a brass made 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.
  • 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. The SIGMA 17-70mm F2.8-4 DC MACRO OS HSM will all be checked using this “A1” before they are shipped.
  • “Made in Japan” - All Sigma's manufacturing – right down to the molds and parts – is carried out under an 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.
