RONKONKOMA, NY--(Marketwire - September 14, 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 the new 70-300mm F4-5.6 DG OS lens.
This compact, telephoto zoom lens provides an extremely long zoom range
that can capture an array of subject matter spanning from portrait to
sports photography. In fact, with smaller chip cameras from Canon, Nikon,
Sony and Pentax, this large-aperture lens' focal length grows to the
equivalent of about 105-450mm.
The 70-300mm F4-5.6 DG OS is also equipped with Sigma's unique Optical
Stabilization (OS) technology, which is Sigma's exclusive anti-shake
feature offering this lens 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, coupled with its
9-blade diaphragm and Special Low Dispersion (SLD) glass, has led Sigma to
rate this lens as one of its best in optical performance.
"This is typically the first lens a new photographer would purchase after
mastering his or her 'kit' or standard lenses and, for the most part, this
is the only accessory lens they would need," said Mark Amir-Hamzeh, general
manager of Sigma Corporation of America. "The 70-300mm's range is simply
amazing and its compact nature, along with the OS system, make it
convenient for travel and hand-held, telephoto photography."
The SLD glass element in the 70-300mm F4-5.6 DG OS provides correction for
all types of aberrations and is supplemented by the Super Multi-Layer
Coating's reduction of flare and ghosting, while providing high contrast
images throughout the focal range. The lens' rounded 9-blade diaphragm also
creates an attractive blur in the out-of-focus areas of the photograph.
With regard to its compact construction, the lens is measured at a length
of five inches, with a maximum diameter of three inches and a weight of
just 21.5 ounces. The 70-300mm F4-5.6 DG OS lens' minimum focusing distance
is 59.1 inches throughout the entire zoom range and it has a maximum
magnification ratio of 1:3.9, making it ideal for close-up photography.
The 70-300mm F4-5.6 DG OS comes with a large lens hood to block out
extraneous light and reduce internal reflection, and is currently available
in Sigma, Canon, Nikon (D), Sony (D) and Pentax mounts for $599 MSRP in
stores nationwide.
