Photokina 2006: Sigma has announced another digital-only lens, the new 18-200 mm F3.5-6.3 DC OS lens. This compact lens offers a big 11x zoom range in combination with Sigma's own Optical Stabilizer. Just like the 18-50 mm DC lens this one features aspherical and low dispersion elements as well as multi-layer coating to reduce flare and ghosting. On the downside it is slow (F6.3) at telephoto (you can't have everything at this price). On a digital SLR with a 1.5x FOV multiplier this lens provides an equivalent field of view of 27-300 mm on a 35 mm camera.
Sigma 18-200 mm F3.5-6.3 DC OS lens

Two SLD (Special Low Dispersion) glass elements and two aspherical lenses provide excellent correction for all types of optical aberrations.
The Sigma Corporation is please to announce the new 18-200mm F3.5-6.3 DC OS lens. This high zoom ratio lens is exclusively designed for digital SLR cameras and is capable of covering a wide range of focal lengths from wide angle to telephoto. It is equipped with Sigma’s own unique technology OS (Optical Stabilizer) function. This function uses two sensors inside the lens to detect vertical and horizontal movement of the camera and works by moving an optical image stabilizing lens group, to effectively compensate for camera shake. It automatically detects movement of the camera and compensates for camera shake when shooting moving subject such as motor sports. Two SLD(Special Low Dispersion)glass elements and two aspherical lenses provide excellent correction for all types of aberrations. The super multi-layer lens coating reduces flare and ghosting. This lens provides superior image quality throughout the entire zoom range. An inner focusing system eliminates front lens rotation, making the lens particularly suitable for using circular polarizing filters and the petal-type lens hood supplied.
