RONKONKOMA, NY--(Marketwire - December 4, 2009) - Sigma Corporation (
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,
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.
