Sigma AF 18-200mm f/3.5-6.3 DC OS (Optical Stabilizer) Zoom Lens for Nikon Digital SLR Cameras
Saturday, October 31st, 2009Sigma AF 18-200mm f/3.5-6.3 DC OS (Optical Stabilizer) Zoom Lens for Nikon Digital SLR Cameras Review

I bought this lens for my son’s wrestling tournaments and was not disappointed. Even indoors without a flash it was fast enough for great shots when they weren’t moving too fast. Reviews said the Canon and Tamron superzooms have better IQ, but they cost 0 more, and I wasn’t ready to spend that.
I’m keeping the lens on the camera more and more, only changing for my 50mm 1.4 for portraits or when I need the best IQ.
For a single walkaround lens, for the money, I don’t think it can be beat.

Sigma AF 18-200mm f/3.5-6.3 DC OS (Optical Stabilizer) Zoom Lens for Nikon Digital SLR Cameras Overview
The Sigma 18-200 F3.5-6.3 DC OS HSM Lens incorporates an Optical Stabilizer function and is exclusively designed for digital SLR cameras. It is perfectly suitable for low-light conditions; whether indoors, at dusk, or in the telephoto range. This system uses two sensors inside the lens to detect vertical and horizontal movement of the camera, and effectively compensates for camera shake by moving an optical image-stabilizing lens group. It also automatically detects panning movement of the camera and compensates for camera shake when shooting moving subjects such as motor sports. SLD (Special Low Dispersion) glass and aspherical glass provide excellent correction for all types of aberrations. This lens has a minimum focusing distance of 45cm (17.7″) throughout the entire zoom range and has a maximum magnification of 1:3.9. Since the inner focusing system means the front of the lens does not rotate, optional circular polarizing filters and the supplied petal-type hood can easily be used. A magnification scale is displayed on the lens barrel, ensuring ease of use. A zoom-lock switch mechanism is provided to prevent the lens from creeping due to its own weight. 69.3 - 7.1 degrees (Sigma SD format) angle of view 7 Diaphragm Blades F22 Minimum Aperture 45cm / 17.7 Minimum Focusing Distance 1 - 3.9 Maximum Magnification Petal Lens Hood Fully compatible with All Nikon Digital SLR cameras including the D40 and D40x Dimensions - Diameter 79mm x Length 100mm Weight - 21.5 ounces (610 grams)
Sigma AF 18-200mm f/3.5-6.3 DC OS (Optical Stabilizer) Zoom Lens for Nikon Digital SLR Cameras Specifications
The Sigma 18-200mm high-zoom-ratio lens is designed exclusively for Nikon digital SLR cameras and is capable of covering a wide range of focal lengths, from wide-angle to telephoto. Two Special Low Dispersion (SLD) glass elements and two hybrid aspherical lenses correct for all types of aberrations, letting Sigma house the extended-range super-zoom lens in a compact and lightweight body that measures 70mm in diameter and 78.1mm long and weighs a mere 14.3 ounces. The new lens coating, meanwhile, reduces flare and ghost–a common problem shared by many digital cameras–while also creating an optimum color balance. Other details include a minimum focusing distance of 45cm (17.7) at all focal lengths, a high zoom ratio of 11:1, and a maximum magnification of 1:4.4.
The lens design incorporates an inner focusing system that prevents the front of the lens from rotating, making it particularly suitable for using circular polarizing filters and petal-shaped lens hoods. In addition, the overall length of the lens never changes during focusing, making the lens convenient to handle and easy to use. Finally, the lens’s zoom lock switch eliminates “zoom creep” during transport–a convenient addition when traveling. The lens, which includes a metal mount, is backed by a one-year warranty.
