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.”

From Sigma Corporation of America: 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. B&H

From Sigma Corporation of America:
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.

is reporting that one of two existing preproduction Sigma 180mm f/2.8 OS Lenses has gone missing at CES.
Sigma staff were reportedly "mystified" when they discovered the lens missing on the second morning of the show.

One of the tasks that I am far behind on is adding sample pictures to the site. To begin addressing this issue, I have added a batch of sample pictures to the site
Many Canon EOS DSLRs and many lens brands and models are represented in this batch. I hope to add many more pictures in the near future.
Be sure to read the tips and other comments below each picture.

In a noticed issued today, Nikon Corporation has indicated that it has filed a patent infringement lawsuit against Sigma:
Nikon Corporation filed a patent infringement lawsuit in Japan
Nikon Corporation (KIMURA Makoto, President, Tokyo, hereafter referred to as "Nikon") filed a patent infringement suit against Sigma Corporation (hereafter referred to as "Sigma") to Tokyo District Court on May 25, 2011. Nikon's lawsuit seeks an injunction against Sigma's manufacture and sale of infringing interchangeable lenses with vibration reduction for single lens reflex cameras, along with damages for past infringement.
Nikon has invested considerable resources in the form of research and development over a period of many years. Such investments have created intellectual property that are important business assets of Nikon and have enabled Nikon to continuously provide the products and services that satisfy its customers requirements.
Although Nikon attempted to resolve Sigma's patent infringement through negotiation, a non-adversarial resolution could not be reached. Consequently, Nikon concluded that filing a lawsuit was the only way it could protect its intellectual property.
