Sigma's latest version of their 17-70mm lens, now including a HSM auto-focus motor. A compact lens with great optical qualities, it can be used for a wide variety of subjects and it is an ideal large aperture standard zoom lens for digital SLR cameras featuring APS-C size image sensor What Sigma says about it: Minimum focusing distance of 20cm (7.9") and maximum magnification of 1:2.3 - This lens has a minimum focusing distance of 20cm (7.9") throughout the entire zoom range. Maximum magnification of 1:2.3 enables close-up photography like a macro lens. It has a 3cm (1.2") working distance between the lens and subject and it is very convenient for taking close-up pictures.
Reduced Ghosting and Flare - The new multi layer lens coating and lens design reduce flare and ghost, which is a common problem with digital cameras and also creates an optimum color balance through the entire zoom range.
Aspherical lens elements & SLD lens - A Special Low Dispersion (SLD) lens and two aspherical lens elements provide excellent correction for all types of aberrations and produce a high level of optical performance throughout the entire zoom range.
F2.8mm (at 17mm focal length) - This lens offers a large aperture of F2.8 at 17mm wide angle and performs superbly even in relatively low light conditions indoors or at dusk.
Inner focusing system - Because the front of the lens does not rotate, circular polarizing filters and a petal-type hood can easily be used. An inner focusing system eliminates front lens rotation, making the lens particularly suitable for using the petal-type lens hood supplied and also circular polarizing filters.
Magnification scale - A magnification scale is displayed on the lens barrel, ensuring ease of use.
Zoom lock switch mechanism - A zoom lock switch mechanism is provided to prevent the lens from creeping due to its own weight, and to avoid the danger of the lens receiving a shock while it is being carried.
HSM (Hyper Sonic Motor) for Nikon Mounts Only - The Incorporation of HSM is capable of autofocusing with all Nikon DSLR cameras.
