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.
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.
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.
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.
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”.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.

COLOGNE, Germany, Sept. 17, 2012 – 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 family-owned and operated company’s Sigma Global Vision from an invite-only event at photokina 2012 in Cologne, Germany.
This announcement explains the restructuring of the Sigma lens lineup into three new categories, the launch of a new lens in each of those categories, the development of a new quality control inspection and measurement system for the lenses, and the design of new software and a USB docking station that will enable photographers to update and adjust their lenses to suit their personal preferences.
“We’re moving in a new direction that simplifies the lens selection process for photographers and helps them realize the full potential of the DSLR system,” said CEO Kazuto Yamaki. “In addition to making it easier for photographers to find the right lens, we’re empowering them with more control over their equipment, while furthering our commitment to them by establishing a higher expectation for the quality of the lenses we produce.”
New lens categories and new lenses
Starting immediately, all newly produced interchangeable lenses from Sigma will be designed for and organized into one of three product categories: Contemporary, Art and Sports. Each line has a clearly defined concept to guide shooters in the selection of the right lens for their photographic interests.
Contemporary – These lenses incorporate the very latest technology and keep size and weight to a minimum, without compromising their advanced optical performance or utility. High-performance, versatile, compact and superbly portable, these lenses will be largely comprised of standard zooms, telephoto zooms and high-magnification zooms for an array of photography, including landscape and travel photography, and casual portraiture.
Art – These lenses are developed with an emphasis on artistic touch and are designed to meet the expectations of users who value a creative, dramatic outcome. Along with landscapes, portraits, still-life, close-up and casual snaps, these lenses are perfect for the kind of photography that unleashes the inner artist. Ideal for studio photography, they offer just as much of an expressive scope when capturing architecture, starry skies, underwater shots and many other scenes. This category will be comprised of many focal lengths and designs, such as large-aperture prime lenses, wide-angle lenses, ultra wide-angle lenses, and macro and fisheye lenses.
Sports - With their high-level optical performance and expressive power, these lenses can capture fast-moving subjects, even at distance. This line also offers a variety of functions to aid the photographer in challenging conditions and scenarios. Besides sports photography, the lenses are also ideal for nature shots featuring birds, wild animals and other creatures, and for the capture of aircraft, trains, race cars and more. The Sports line is also unique in that users can adjust the lenses’ focus speeds and the focus limiters via a button on the lens. The Sports category will be comprised of telephoto lenses, telephoto zoom lenses, super telephoto lenses, super telephoto zoom lenses, and more.
The creation of these new categories comes with the introduction of three new lenses:
17-70mm F2.8-4 DC MACRO OS HSM – This new Contemporary lens is designed for cameras with an APS-c sensor and covers a range equivalent to 25.5 to 105mm on a 35mm camera. An upgrade to its predecessor, which was released in December 2009, this general purpose lens offers a new design and a more compact build.
35mm F1.4 DG HSM – This Art lens provides photographers with a state-of-the-art alternative to the more conventional 50mm. This lens’ axial chromatic aberration is minimized, which renders a cool and smooth out-of-focus image. At low apertures, it can perform like a wide-angle lens; when opened up to F1.4, it will provide background bokeh and make the subject pop like a mid-range telephoto lens.
120-300mm F2.8 DG OS HSM – With redesigned mechanics and performance, this Sports lens is an update from its predecessor released in February 2011. This high-performance lens eases difficult shooting conditions by offering a maximum focal length of 300mm and a wide-open aperture of F2.8. This lens, like the other Sports category lenses to come, is dust and moisture resistant, and allows users to adjust the focus speed and the focus limiter via a button on the lens.
New user-control tools and software, and new quality control measures
The new Sigma Optimization Pro software and USB Dock are designed exclusively for the new lenses within the new product lines. They will enable Sigma users to connect their lenses to their computers to update lens firmware and fine-tune focus parameters via easy-to-use, on-screen controls.
All of these new lenses will also be subject to Sigma’s new, proprietary modulation transfer function (MTF) measuring system called “A1.” Named in honor of the company’s sole production base, the Aizu factory in Aizu, Japan, the A1 system will allow inspectors to verify previously undetectable high-frequency details in each lens before it is shipped.
“We used to measure lens performance with a MTF measuring system using conventional sensors, but this new A1 system uses our own 46-megapixel Foveon direct imaging sensors,” said Yamaki. “We view this new method of performance evaluation as being incredibly important, not only because we owe it to our customers, but because we owe it to ourselves. We’ve spent more than 50 years perfecting our design and manufacturing processes, and now we deliver a complete package by closing the loop on that commitment to quality by adopting a more stringent verification process.”
Newly designed telephoto zoom lens with Sigma’s own Optical Stabilizer system at street price of $1099
Ronkonkoma, NY, March 30, 2012 – 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 its newly upgraded 50-150mm F2.8 APO EX DC OS HSM telephoto lens is now available for the street price of $1,099.
The 50-150mm F2.8 APO EX DC OS HSM telephoto lens is the successor to the 50-150mm F2.8 APO EX DC II HSM. The updated lens now features Sigma’s own proprietary Optical Stabilizer (OS) technology, which offers the use of shutter speeds approximately four stops slower than would otherwise be possible. The lens design utilizes an inner-focusing and inner-zooming system that provides convenient handling and this, along with the OS feature, makes it favorable for high-performance, handheld, close-up photography. Additionally, the Hyper Sonic Motor (HSM) ensures quiet and high-speed auto focusing, while allowing full-time manual focus capability.
The Sigma 50-150mm F2.8 APO EX DC OS HSM Canon mounts will be available next week, while the Nikon and Sigma mounts are expected to be available by the end of April.
“This lens is a great addition to our lineup of telephoto lenses, and will be a fantastic tool for portrait, landscape and nature photography,” said Mark Amir-Hamzeh, president of Sigma Corporation of America. “This is our tenth telephoto lens with Optical Stabilizer technology and provides another option for photographers looking to produce high-quality images.”
Six SLD glass elements provide exceptional corrections for all types of aberrations and provide high-quality imagery throughout the zoom range. It also has a rounded, nine-blade diaphragm that creates an attractive blur to the out-of-focus areas of the image.
The lens’ Super Multi-Layer Coating reduces flare and ghosting and ensures sharp and high contrast images even at the maximum apertures. The addition of Sigma’s 1.4x EX DG APO and 2x EX DG APO teleconverters produce a 70-210mm F4 autofocus telephoto zoom lens and a 100-300mm F5.6 autofocus telephoto lens, respectively.
Sigma Corporation of America announces the passing of Michihiro Yamaki
Imaging manufacturer’s pioneering CEO, founder led company for more than 50 years
RONKONKOMA, NY, Jan. 27, 2012 – With great sadness, Sigma Corporation of America today announced the passing of Sigma Corporation’s founder and CEO Michihiro Yamaki. He died of liver cancer in Tokyo, Japan, on Jan. 18 at the age of 78.
“We are deeply saddened by this loss,” said Mark Amir-Hamzeh, president of Sigma Corporation of America. “Mr. Yamaki was an industry visionary, and his leadership and enthusiasm has been the driving force behind our company’s innovation for more than 50 years. We’re sending our deepest condolences to the Yamaki family, and our entire Sigma family around the world, during this very difficult time.”
Yamaki founded Sigma Corporation on Sept. 9, 1961 with the development of the first-ever rear attached lens converter. At that time, most photo enthusiasts believed that a lens converter could only be attached to the front of a camera lens and the 27-year-old optical engineer turned conventional optical theory on its head. Sigma Corporation celebrated its 50th anniversary in 2011 with Yamaki still at the company’s helm.
Throughout his years in the photo industry, Yamaki has been focused on producing high-quality, high-performance photographic technology at moderate prices. His goal for the company has always been to make outstanding image quality accessible to all photographers. To this end, he grew the family-owned organization into a leading researcher, developer, manufacturer and service provider of lenses, cameras and flashes. The company is now known as the largest, independent SLR lens manufacturer in the world, producing more than 50 current lenses that are compatible with most manufacturers, including Sigma, Canon, Sony, Nikon, Olympus, Pentax and Sony.
In 2008, under Yamaki’s direction, Sigma Corporation purchased Foveon, a California-based company that’s renowned for developing the X3 image sensor technology. This patented, three-layer image sensor captures all primary RGB colors at each pixel location arranged in three layers to deliver outstanding, high-resolution, high-definition images with impressive three-dimensional detail and rich gradation. Last year, the company announced the arrival of its SD1, a groundbreaking, 46-megapixel direct image sensor camera, offering more megapixels than any other DSLR currently on the market. Sigma Corporation continued its theme of addressing gaps in the industry and the needs of photographers by kicking off 2012 with the launch of its new, Digital Neo (DN) line of lenses for Micro Four Thirds and E-mount camera systems.
In addition to his inventions and photographic foresight, Yamaki made many other contributions to the industry in his 78 years of life. He served organizations such as: the Japan Photographic Enterprises Association, Japan Machinery Design Center, Japan Optomechatronics Association, Photographic Society of Japan, and Japan Camera Industry Institute. He has also been honored with the “Person of the Year” award from The Photoimaging Manufacturers & Distributors Association (PMDA), the “Hall of Fame” award from the International Photographic Council (IPC), and the Golden Photokina Pin for his longtime contribution to the imaging industry.
