 Sigma 18-125mm F3.5-F5.6 DC lens launch : Sigma announces the launch of the new Sigma 18-125mm F3.5-5.6 DC. This Sigma 18-125mm F3.5-F5.6 DC zoom lens was exclusively designed for use with digital Single-Lens Reflex (SLR) cameras and has 6.9x high magnification zoom ratio. A Special Low Dispersion (SLD) and two pieces of aspherical glass elements produce high level of optical performance through the entire zoom range and also this has resulted in a compact, lightweight lens that features a length of 77.7mm (3"), maximum diameter of 70mm (2.7"), weight of 385gr (13.5oz) and filter size of just 62mm. The new lens coating reduces flare and ghost, which is a common problem of digital cameras and also creates an optimum color balance.
