Hot on the heels of the Sigma SD15 announcement, Sigma UK has unveiled the suggested retail price of the new 17-50mm f2.8 EX DC OS HSM standard zoom lens. Designed for DSLR cameras with APS-C sized sensors, the lens incorporates two FLD glass elements whose performance is equal to that of fluorite glass. The inner focusing system eliminates front lens rotation, making the Sigma 17-50mm f2.8 particularly suitable for use with the supplied petal-type lens hood and circular polarising filters, while the Hyper Sonic Motor makes for fast and quiet focussing. Available now in Canon fit, the lens will also come in Sigma, Nikon, Sony and Pentax versions shortly. The suggested retail price is £649.99.

Sigma Imaging (UK) Ltd is pleased to announce that the suggested retail price of the new 17-50mm f2.8 EX DC OS HSM lens is £649.99. This new lens is available now in Canon fit and will be available shortly in Sigma, Nikon, Sony and Pentax fit.

This large aperture standard zoom lens is designed for digital SLR cameras and incorporates Sigma’s efficient OS function.  This lens covers a focal length from 17mm wide angle and offers a large aperture of F2.8 throughout the entire zoom range, making it ideal for many types of photography such as portraiture and landscapes.  The OS (Optical Stabiliser) function offers the use of shutter speeds approximately 4 stops slower than would otherwise be possible. 

Two FLD (“F” Low Dispersion) glass elements, which have performance equal to fluorite glass, plus two glass mold and one hybrid aspherical lens, provide excellent correction for all type of aberrations.  The Super Multi-Layer Coating reduces flare and ghost. 

Incorporating HSM (Hyper Sonic Motor), the lens provides fast and quiet AF.  The lens has a minimum focusing distance of 28cm (11”) throughout the entire zoom range and a maximum magnification ratio of 1:5.  The rounded 7 blade diaphragm creates an attractive blur to the out of focus images.  The inner focusing system eliminates front lens rotation, making the lens particularly suitable for use with the supplied petal-type lens hood and circular polarising filters.

* Vignetting will occur if the lens is used with digital cameras with image sensors larger than APS-C size or 35mm SLR cameras. * For Pentax and Sony mount, when the OS function of lens body is used, please turn the stabilizer function of camera body off.  * It is not possible to use the built-in OS function and AF of this lens with Pentax ist *series and the K100D.
