EX series large aperture zoom lens designed specially for use with digital SLR cameras with a minimum focusing distance of 20cm.

This lens has a large aperture of F2.8 throughout the entire zoom range, a minimum focusing distance of 20cm (7.9”) and a maximum magnification of 1:3, making it ideal for close-up photography.
Specially designed to suit the characteristics of digital SLR cameras this lens provides a high level of optical performance.Its design incorporates both glass-mold and hybrid aspherical lens technology which offers superior peripheral brightness, extremely high image quality as well as a compact and lightweight construction.

Special Low Dispersion (SLD) and Extraordinary Low Dispersion (ELD) glass elements provide excellent correction of color aberrations. The super multi-layer lens coating reduces flare and ghosting, a common problem with digital cameras. High image quality is assured throughout the entire zoom range. An inner focusing system eliminates front lens rotation, making the lens particularly suitable for using the petal-type lens hood (supplied) plus circular polarizing filters.



The Sigma 18-200mm 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.

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.
