Sigma Corporation recently introduced the new 17-50mm F2.8 EX DC OS HSM lens. This large-aperture, standard-zoom lens 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 billed as an “ultra compact lens” with an overall length of just 3.6 inches.
The new lens 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.
Sigma claims the OS function offers the use of shutter speeds approximately four stops slower than would otherwise be possible. The company adds that only they have 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.”
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.
