PRESS RELEASE: Sigma 18-200mm F3.5-6.3 DC OS
11.1 times high magnification zoom ratio lens is exclusively designed for digital SLR cameras, and equipped with OS (Optical Stabilizer) function.
The Sigma Corporation is please to announce the launch of the new 18-200mm F3.5-6.3 DC OS lens.
This 11.1 times high magnification 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 also automatically detects movement of the camera and compensates for camera shake when shooting moving subjects such as motor sports.
SLD（Special Low Dispersion）glass and three aspherical lenses provide excellent correction for all types of aberrations. The super multi-layer lens coating reduces flare and ghosting.
High image quality is assured throughout the entire zoom range. This lens has a minimum focusing distance of 45cm (17.7") at all focal lengths, and has maximum magnification of 1:3.9, making it ideal for close-up photography. 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.
