RONKONKOMA, N.Y., - Aug. 1, 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 a revolutionary new, fee-based service that will enable the company’s Global Vision lens owners to change their lens mounts for use on different camera systems.
Starting Sept. 2, Global Vision lens owners can request the Mount Conversion Service to convert their current Sport, Contemporary or Art DSLR lenses to their choice of a Sigma, Sony, Pentax, Nikon or Canon mount. Global Vision category lenses for mirrorless interchangeable lens cameras (MILCs) can be updated to either a micro four thirds (MFT) or Sony E- mount.
In addition to the announcement of the industry’s first Mount Conversion Service, Sigma is also extending the warranty on all of its products - including cameras, lenses and flashes purchased on or after July 1, 2013 - to four years. Previously, warranties varied by product. This enhanced product protection provides Sigma’s customers with more consistency and improved service.
“Professionals and amateurs alike are taking advantage of the many affordable camera options in today’s market; they’re updating their camera bags and exploring new systems and brands,” said Mark Amir-Hamzeh, president of Sigma Corporation of America. “When photographers purchase a lens, it’s often a significant, financial and artistic commitment - and we believe that investment should last a lifetime. Our new Mount Conversion Service and extended warranty are intended to help Sigma users get more enjoyment from our products, regardless of how their approach to photography changes overtime.”
The Mount Conversion Service is limited to all of Sigma’s Global Vision lenses. Current, applicable full-frame lenses include the 120-300mm F2.8 DG OS Sport and 35mm F1.4 DG Art; APS-C crop sensor lenses include the 30mm F1.4 DC HSM Art, 17-70mm F2.8-4 DC OS Macro Contemporary and 18-35mm F1.8 DC Art; and MILC lenses include the 19mm F2.8 DN Art, 30mm F2.8 DN Art and 60mm F2.8 DN Art. Lenses can be converted to any mount of a photographer’s choosing, as long as Sigma has released that product in the requested mount.
Cost of the conversion will range between $80 to $250, plus shipping costs, depending on the focal length of the lens. All lenses will be shipped to Sigma’s US subsidiary in New York, and updated, calibrated and optimized for the new camera system at Sigma’s factory in Aizu, Japan. All lenses that undergo the Mount Conversion Service will be covered under warranty for six months following the update. Teleconverters, USB Docks and other accessories are not eligible for the service.
To request the Mount Conversion Service, please visit your local Sigma subsidiary. Customers in the United States should visit www.sigmaphoto.com.

Adorama has started shipping the Sigma 18-35mm f/1.8 DC HSM Lens (for Canon) to preorder customers. If you're already in line, you can probably expect yours to arrive in the not-so-distant future. ;-)
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.

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 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.
