- Lens Construction - 15 Elements in 12 Groups
- Angle of View - 72.4 - 20.2 degrees
- 7 Diaphragm Blades

The lens also offers a large aperture of F2.8 at the 17mm wide-angle setting, yet is notably compact, with an overall length of 3.2 inches and a diameter of 3.1 inches. Plus, it performs superbly even in relatively low-light conditions, such as indoors or at dusk. Users will also appreciate the inner focusing system, which provides a fast autofocus speed while preventing the front of the lens from rotating, making it particularly suitable for use with circular polarizing filters and petal-shaped lens hoods. Also equipped with a zoom lock switch that eliminates "zoom creep" during transport, the lens weighs 16 ounces and carries a one-year warranty.

Sigma Corporation is pleased to announce the launch of the new 17-70mm F2.8-4.5 DC MACRO lens. 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.Features: Large...
