Sigma APO 70-200mm F2.8 EX DG OS HSM lens

Press Release:

Sigma has announced that its new, optically stabilized APO 70-200mm F2.8 EX DG OS HSM lens, which contains the company’s new “F” Low Dispersion (FLD) lens glass, is now available in the United States for the MSRP of $2,470.

The APO 70-200mm F2.8 EX DG OS HSM lens was first announced at the PMA International Convention in February and is currently available in Canon mounts. It will soon be available for purchase in Nikon, Sigma, Sony and Pentax mounts. This second-generation lens is designed for use with full-frame, DSLR cameras and may also be used with smaller, APS-c size sensors with a corresponding effective increase in focal length of 100-300mm with most cameras.

This new addition to Sigma’s lineup of more than 50 lenses covers a medium telephoto range of focal lengths from 70mm to 200mm with a large, maximum aperture of F2.8 throughout the entire zoom range. It’s revered for its incorporation of Sigma’s unique Optical Stabilization (OS) technology, which allows photographers to use shutter speeds approximately four stops slower than would otherwise be possible, while maintaining its predecessor’s compact dimensions. Moreover, the lens offers two modes of optical stabilization: The first is for general photography and the second is specifically designed for panning with moving subjects. Sony and Pentax shooters who are accustomed to the anti-shake system in their cameras are able to choose between that internal function and the lens’ OS capabilities.

“The 70-200mm has historically been a very popular lens in our collection of telephoto zoom lenses,” said Mark Amir-Hamzeh, general manager of Sigma Corporation of America. “With its large aperture, it’s impressively sharp in low-light situations and its zoom range makes it a versatile option for photographers and photojournalists on the go. It’s truly one of those all-occasion, must-have lenses.”

The 70-200mm F2.8 EX DG OS HSM also features Sigma’s Hyper Sonic Motor (HSM) technology, which ensures quiet and high-speed auto focus and full-time manual focus capability. The lens has a minimum focusing distance of 55.1 inches throughout the entire zoom range and a maximum magnification ratio of 1:8. The rounded, nine-blade diaphragm creates an attractive blur to the out of focus images. This lens is equipped with a petal-type hood and, for APS-C size image sensor cameras, it comes with a dedicated hood adapter that expands to the length of the lens hood.

The lens has two of Sigma’s new FLD glass elements. This is the highest level, low dispersion glass available and it has extremely high light transmission with a performance equal to fluorite glass. The new 70-200mm also has three Special Low Dispersion (SLD) glass elements for excellent correction of color aberration and Super Multi-Layer Coating to reduce flare and ghosting.
