Sigma 18-200mm f/3.5-6.3 DC Lens for Canon Digital SLR Cameras
From the Manufacturer
This high zoom ratio lens is exclusively designed for digital SLR cameras and 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 offer the utmost correction for all types of aberrations, and enables this extended range super zoom lens to be housed in a compact and lightweight construction of 70 millimeter (2.8 inches) diameter, and 78.1 millimeters (3.1 inches) in length, and weighing just 405 grams / 14.3 ounces. The new lens coating reduces flare and ghost, which is a common problem of digital cameras and also creates an optimum color balance. This lens has a minimum focusing distance of 45 centimeters (17.7 inches) at all focal lengths and has maximum magnification of 1:4.4.
The lens design incorporates an inner focusing system, which prevents the front of the lens from rotating, making it particularly suitable for using circular polarizing filters and petal shaped lens hoods. The overall length of the lens does not change during focusing, ensuring convenient handling and ease of use. A zoom lock switch eliminates 'zoom creep' during transportation, a convenient addition when traveling.
Note to customers: Vignetting will occur if the lens is used with digital cameras with image sensors larger than APS-C size or 35mm SLR cameras.
