Sigma reveals 18-200mm F3.5-6.3 II DC OS HSM with ‘FLD’ glass

Sigma has released version II of its 18-200mm F3.5-6.3 DC OS HSM superzoom lens. The latest version adds Sigma’s FLD glass, the ‘fluorite-like’ glass co-developed with Hoya and features a revised design (it now features a narrower body and 18 elements in 14 groups, rather than the 13 groups of its predecessor). The lens will be available for Canon, Nikon, Sigma, Pentax and Sony systems (without optical stabilization on the last two mounts). MSRP will be $720.

SIGMA 18-200mm F3.5-6.3 II DC OS HSM

The Sigma Corporation is pleased to announce the release of the SIGMA 18-200mm F3.5-6.3 II DC OS HSM. This 11.1x high zoom ratio lens is designed exclusively for digital SLR cameras, incorporates Sigma’s original OS (Optical Stabilizer) function and offers a broad shooting range from wide angle to telephoto.

The SIGMA 18-200mm F3.5-6.3 II DC OS HSM is the successor to the SIGMA 18-200mm F3.5-6.3 DC OS/ HSM which was launched in June 2007. The lens is ideal for travel photography with a compact construction and length of just 87.7mm. This lens features FLD (“F” Low Dispersion) glass elements, which have the performance equal to fluorite glass, and SLD (Special Low Dispersion) glass elements providing excellent correction of color aberration. Aspherical lenses give excellent correction for all types of aberration and distortion. The Super Multi-Layer Coating reduces flare and ghosting, ensuring high quality images throughout the entire zoom range. Sigma’s OS (Optical Stabilizer) system offers effective correction of approximately 4 stops, enabling easy handheld photography. HSM (Hyper Sonic Motor) ensures quiet, high-speed auto focus and the inner focus system eliminates front lens rotation, making the lens particularly suitable for using the supplied petal-type lens hood and circular polarizing filters. The rounded 7 blade diaphragm creates an attractive blur to the out of focus areas of images.

* Sony and Pentax mounts do not incorporate Optical Stabilization

* FLD glass is the highest level low dispersion glass available with extremely high light transmission. The optical glass has a performance equal to fluorite glass which has a low refractive index and low dispersion compared to current optical glass. It also benefits from high anomalous dispersion. These characteristics give excellent correction for residual chromatic aberration (secondary spectrum) which cannot be corrected by ordinary optical glass and ensures high definition and high contrast images.
* Vignetting will occur if the lens is used with image sensor larger than APS-C size or 35mm SLR, and APS Film SLR cameras.
* For Pentax mount, auto focus will not be available on Pentax ist* series and K100D.
* The appearance and specification are subject to change without notice.

Sigma Corporation shares pricing, availability for three weather-resistant lenses

Sigma Corporation of America (www.sigmaphoto.com), a leading researcher, developer, manufacturer and service provider of some of the world’s most impressive lines of lenses, cameras and flashes, has announced the pricing and availability for three lenses that incorporate the company’s new, weather-resistant design.

The Sigma APO 120-300mm F2.8 EX DG OS HSM and APO MACRO 150mm F2.8 EX DG OS HSM were first introduced at Photokina in September 2010. Those lenses will be available for purchase in late February and the end of March for the U.S. manufacturer’s suggested retail price (MSRP) of $4,700 and $1,600, respectively.  In April, they will be joined by a weather-resistant update to another old favorite, the 12-24mm F4.5-5.6 II DG HSM, for the U.S. MSRP of $1,400. All lenses will be released in Nikon and Canon mounts first, and will be available in Sigma, Pentax and Sony mounts shortly thereafter.

“We’ve updated these popular lenses with our latest technology and design, while maintaining their compact size,” said Mark Amir-Hamzeh, president of Sigma Corporation of America. “The 120-300mm and the 150mm are now optically stabilized (OS), and all three lenses contain our new, weather-resistant design, which will offer protection from water and dust. These are fantastic upgrades to already-great lenses.”

In addition to sharing the pricing and availability of these three lenses, Sigma Corporation has also revealed plans for its DP2x, APO 50-150mm F2.8 EX DC OS HSM, and MACRO 105mm F2.8 EX DG OS HSM. The DP2x is a successor to the DP2 that will now include Analog Front End (AFE) and high speed auto focus, and the new 50-150mm will replace its predecessor and offer Sigma’s proprietary OS technology. The new Macro 105mm is an upgrade that includes the company’s Hyper Sonic Motor (HSM) and OS technologies, as well as the new, weather-resistant design. Pricing and availability for these products have not yet been announced.

In the meantime, Sigma is sharing more details about the three new, weather-resistant lenses that will be available in the coming months:

  • Sigma’s new 12-24mm F4.5-5.6 II DG HSM is an update to the 12-24mm F4.5-5.6 EX DG ASP HSM, which has been a photographer favorite since it was first introduced in 2002.

Sigma 17-50mm F2.8 EX DC OS HSM

Sigma Corporation of America has announced that the Sigma 17-50 F2.8 EX DC OS HSM is now available. The lens, originally announced at the PMA exhibition in February 2010, offers a faster, image stabilized alternative for APS-C users wanting to upgrade from their kit lens. It is now available in Canon mount with Pentax, Sony, Nikon and Sigma-mount versions expected ‘in the coming weeks.’ The lens will sell with a recommended price of $980.

Sigma 17-50mm F2.8 EX DC OS HSM

Ultra compact, large-aperture, standard zoom packs OS functionality and new, FLD glass

Sigma Corporation, 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 the release of its new 17-50mm F2.8 EX DC OS HSM lens.

This large-aperture, standard-zoom lens, which was first introduced in February at Photo Marketing Association International, is designed for small chip, APS-C digital cameras and incorporates Sigma’s Optical Stabilization (OS) functionality and new, FLD glass. The 17-50mm F2.8 EX DC OS HSM is an ultra compact lens with an overall length of just 3.6 inches.

The 17-50mm F2.8 EX DC OS HSM covers a focal length from a 17mm wide angle, has a minimum focusing distance of 11 inches throughout the entire zoom range and a maximum magnification ratio of 1:5. The lens is currently available in Canon mounts at all authorized Sigma dealers for the MSRP of $980, and it will be available in Nikon, Sigma, Sony and Pentax mounts in the coming weeks.

The OS function offers the use of shutter speeds approximately four stops slower than would otherwise be possible. Only Sigma has made it possible for Pentax and Sony shooters to utilize an anti-shake system in either the lens or the camera body. The compensation for camera shake is visible in the view finder for all mounts, which makes accurate focusing fast and easy.

“This lens is a must-have for any photo opportunity,” said Mark Amir-Hamzeh, general manager of Sigma Corporation of America.  “The fast aperture allows for shooting in low, existing light or at maximum range with a flash. This is an ideal, all-purpose lens for everyday shooting.”

Sigma’s FLD glass, which is used in the new lens, has an extremely high light transmission and anomalous dispersion, making it the top level of low dispersion glass available. With a performance equal to fluorite glass, this optical glass has a low refractive index and low dispersion compared to current optical glass. These characteristics offer excellent correction for residual chromatic aberration (secondary spectrum), which cannot be corrected by ordinary optical glass and ensures high-definition and high-contrast images.

In addition, the 17-50mm F2.8 EX DC OS HSM also offers one hybrid aspherical lens and two glass mold elements for excellent correction of distortion and astigmatism. It has Super Multi-Layer Coating to reduce flare and ghosting with superior peripheral brightness and Hyper Sonic Motor (HSM) to provide quiet and high-speed auto focus, as well as full-time manual focus capability. The lens’ rounded, seven-blade diaphragm creates an attractive blur to out-of-focus areas and its inner focusing system eliminates front lens rotation, making the lens particularly suitable for use with the supplied petal-type lens hood and circular polarizing filters.

The Sigma Corporation is pleased to announce the new Sigma 17-70mm F2.8-4 DC MACRO OS HSM.

This large aperture standard zoom lens offers an aperture of F2.8 at the 17mm focal length and is ideal for many situations such as portraits, sports, macro and general photography. The OS (Optical Stabiliser) function offers the use of shutter speeds approximately 4 stops slower than would otherwise be possible. For Sony and Pentax mount, the built-in OS function of this lens can be used even if the camera body is equipped with an anti-shake function. As the compensation for camera shake is visible in the view finder, the photographer can easily check for accurate focus and ensure there is no subject movement. The maximum aperture of F2.8 produces an attractive background blur and improves autofocus speed.

This lens has a minimum focusing distance of 22cm (8.6 inches) throughout the entire zoom range and maximum magnification ratio of 1:2.7, making it ideal for close-up photography. It is possible to focus as close as approximately 4.7cm from the tip of the lens to the subject making this lens particularly useful for close-up photography.

Three aspherical lenses and one ELD (Extraordinary Low Dispersion) glass element provide excellent correction for all types of aberrations. High image quality is assured throughout the entire zoom range. The Super Multi-Layer Coating reduces flare and ghosting and provides high contrast images. The incorporation of HSM (Hyper Sonic Motor) ensures a quiet and high speed AF. This lens has a rounded 7 blade diaphragm which creates an attractive blur to the out of focus areas of the image. The inner focusing system eliminates front lens rotation, making the lens particularly suitable for using the supplied petal-type lens hood and circular polarising filters.

*Autofocus on Pentax version only available on K10D and newer bodies offering HSM/SDM support.
