SigmaSigma 17-70 mm wide angle lens : The Sigma corporation is pleased to announce the new Sigma 17-70 mm f/2.8-4 DC Macro OS HSM wide angle lens. The large aperture wide angle lens offers an aperture of f/2.8 at the 17 mm focal length and is ideal for many situations such as portraits, sports, macro and general photography. The optical stabilizer (OS) functions offers the use of shutter speeds approximately 4 stops slower than would otherwise be possible. For Sony and Pentax mount, the built-in OS functions of the Sigma 17-70 mm wide angle zoom lens can be used even if the camera body is equipped with an anti-shake function. The compensation for camera shake is visible in the view finder, so you can easily check for accurate focus.

Improved AF speed with Sigma wide angle lens
The maximum aperture of f/2.8 produces an attractive background blur and improves autofocus speed. The Sigma 17-70mm DC Macro HSM wide angle lens has a minimum focusing distance of 22 cm (8.7in) throughout the entire zoom range and maximum magnification ratio of 1:2.7, making it ideal for close-up photography. Three aspherical lenses and one ELD (Extraordinairy Low Dispersion) glass element provide excellent correction for all types of aberrations.

Sigma 17-70 mm DC Macro OS HSM wide angle lens offers quit auto focus
High image quality is assured throughout the entire zoom range. The Super Multi-Layer Coating of the Sigma wide angle lens reduces flare and ghosting and provides high contrast images. The incorporation of HSM (Hyper Sonic Motor) ensures a quiet and high speed AF. The Sigma 17-70 mm wide angle lens has a rounded 7 blade diaphragm which creates an attractive blur to the out of focus areas of the image. The inner focus system eliminates front lens rotation, making the lens particularly suitable for using the supplied petal-type lens hood and circular polarizing filters.
