Ultimate standard lens’ now available in Canon, Nikon, Pentax, Sony and Sigma mounts

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 its newly upgraded 17-70mm F2.8-4 DC Macro OS HSM lens.

This large aperture, standard zoom lens contains state-of-the-art enhancements, including the company’s own Optical Stabilization (OS), anti-shake technology that offers the use of shutter speeds approximately four stops slower than would otherwise be possible. Once again, 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.

This lens’ predecessor, the 17-70mm F2.8-4.5 DC Macro HSM, was deemed a “Best Buy” recommendation for photographers wishing to purchase a standard zoom lens as part of the Canadian Association for Photographic Art’s (CAPA) “Best Lens of the Year” awards.

“Aside from the OS technology, which is key when shooting with mid-range and high-end class DSLRs, this lens stands apart from the crowd because of its impressive zoom range,” said Mark Amir-Hamzeh, general manager of Sigma Corporation of America. “It has a 4x zoom range that is equivalent to 24-105mm lenses in full-frame formats. That, coupled with the OS technology and a macro function, makes it the ultimate standard lens for serious photographers who want top-notch image quality and functionality at an affordable price.”

With a large aperture of F2.8 on the wide end and F4 at the tele end, as well as a macro function with a minimum focusing distance of 8.7 inches and a maximum magnification ratio of 1:2.7, this lens is ideal for a wide range of photography. The lens’ Hyper Sonic Motor (HSM) also ensures a quiet and high speed auto focus, while its rounded, seven-blade diaphragm creates an attractive blur to the out-of-focus areas to provide the optimal Bokeh effect. The inner focusing system eliminates front lens rotation, making the lens particularly suitable for using the supplied petal-type lens hood and circular polarizing filters.

Three aspherical lenses and one Extraordinary Low Dispersion (ELD) glass element provide excellent correction for all types of aberrations when shooting with this lens. Additionally, the Super Multi-Layer Coating reduces flare and ghosting to produce high-contrast images.

The 17-70mm F2.8-4 DC Macro OS HSM lens is currently available in Sigma, Canon, Nikon (D), Sony (D) and Pentax mounts for $680 MSRP in stores nationwide.

Super Multi Coating reduces flare and ghosting that tends to occur when using digital SLR cameras.

When used with a 35mm or full-frame digital SLR camera, this ultra wide angle zoom lens offers 122 degree super wide angle of view along the diagonal axis.

Sigma will always be guaranteed a place in the history books as pioneers of the wide-angle zoom lens. Our advanced super wide angle technology was developed far earlier than any of our competitors.
Sigma designed and produced the first wide-angle zoom lens, the «zoom gamma 21-35mm F3.5-4.2», in 1979. The wide-angle zoom category didn’t even exist before this date. The market comprised only standard and telephoto zoom lenses with most people believing that wide angle zooms were impossible to develop. However Sigma’s advanced design and pioneering technology went on to prove them wrong and strongly influence subsequent product development.

Optimized for Digital SLR Cameras
Four Special Low Dispersion (SLD) glass elements are provided for effective compensation of color aberration, which is a common problem with super-wide angle lenses. Three Aspherical lenses, including two molded glass aspherical lens elements, offer excellent correction for linear distortion as well as all types of aberration. It is an ideal lens for Digital SLR Cameras as well as film SLR cameras.

HSM (Hyper Sonic Motor)
Equipped with Hyper Sonic Motor (HSM) for Sigma, Nikon and Canon.
It is easy to revert to Manual Focus by simply turning the focusing ring and overriding the AF. An inner focus system provides high performance and convenience. The non-rotating lens barrel perfectly suits the matched petal shaped lens hood.

Minimum focusing distance of 28cm/11in. at all focal lengths.
12-24mm F4.5-5.6 EX DG lens offers a minimum focusing distance of 28cm/11in. at all focal lengths.
The super-wide angle’s useful range of view offers the photographer greater freedom of expression.

Fixed Petal-type hood is incorporated
This lens is equipped with a fixed Petal-type hood to obtain a superior extraneous light-blocking effect.
