It can be used with wide variety of subjects and it is an ideal large aperture standard zoom lens for digital SLR cameras featuring APS-C size image sensor. This lens has a minimum focusing distance of 7.9" (20cm) throughout the entire zoom range. Maximum magnification of 1:2.3 enables close-up photography like a macro lens. The new lens design and multi layer lens coating reduce flare and ghosting, which is a common problem with digital cameras. 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. This lens offers a large aperture of F2.8 at 17mm wide angle and yet it is compact, with an overall length of 82.5mm (3.2") and diameter 79mm (3.1"). It performs superbly even in relatively low light conditions indoors or at dusk. The lens design incorporates an inner focusing system, which ensures fast AF speed as well as prevents the front of the lens rotating, making it particularly suitable for use with circular polarizing filters and petal shaped lens hoods. This lens is also equipped with Zoom Lock Switch that eliminates "Zoom Creep" during transportation.| Product Description | Sigma zoom lens - 17 mm - 70 mm | | Lens System | Zoom lens | | Mounting Type | Canon EF | | Lens Aperture | F/2.8-4.5 | | Focal Length | 17 mm - 70 mm | | Optical Zoom | 4 x | | Min Focus Range | 20 cm | | Focus Adjustment | Automatic, manual | | Lens Construction | 12 group(s) / 15 element(s) | | Special Functions | Macro, zoom | | Filter Size | 72 mm | | Length | 8.3 cm | | Weight | 455 g |
