Sigma 18-200mm f/3.5-6.3 DC OS HSM For Nikon

The Sigma 18-200mm f/3.5-6.3 DC OS (Optical Stabilizer) HSM Lens offers an "all-in-one" super-zoom lens solution, from wide-angle to long telephoto. It provides the equivalent focal range of approx. 27-300mm when used with a Nikon digital SLR camera(*). This lens has now been updated with the OS (Optical Stabilizer) system, which minimizes image blur caused by camera shake, and offers the equivalent of shooting at a shutter speed 2-3 stops faster. This allows handheld telephoto zoom shooting even in poorly lit conditions.

The 18-200mm's optical design incorporates aspherical lenses and SLD (Special Low Dispersion) glass, which provides the utmost correction for all types of aberrations. It also enables this extended super-zoom lens to be housed in a compact and lightweight construction.

DC lenses are exclusively designed for digital SLR cameras. The image circle (rear of lens) is sized to match the smaller dimensions used for the image sensor on digital cameras. As a result these lenses are also more compact and lightweight, and are better matched to digital SLR cameras.

- The OS system uses two sensors inside the lens to detect vertical and horizontal movement of the camera. It 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.

- The HSM (Hyper Sonic Motor) system ensures quiet and high-speed auto focusing with full time manual focus override. Incorporation of the HSM feature allows it to autofocus with all Nikon DSLR cameras, including the D40 series.

- Two Special Low Dispersion (SLD) elements and three hybrid aspherical lenses provide high quality images throughout the entire zoom range.

Super Multi Layer (SML) coating reduces ghost and flare.

The lens design incorporates an inner focusing system, which prevents the front of the lens from rotating, thereby making it particularly suitable for use with circular polarizing filters and petal shaped lens hoods.

A magnification scale is displayed on the lens barrel for each focal length, ensuring ease of use.
