Sigma 18-200mm f/3.5-6.3 DC Lens for Nikon Digital SLR Cameras 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 70mm (2.8″) diameter, and 78.1mm (3.1″) in length, and weighing just 405g/14.3oz. 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 45cm (17.7″) 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.
Customer Review: love it!
I’m not an experienced photographer, but this lense (and my Nikon D40) make me feel like I am!! I love this lense. For the money, it’s fabulous!! The only thing that drives me crazy, is that it is manually focused exactly opposite from my old (crummy) lense, but I’m adjusting.
Customer Review: Reeeaaally hard to beat for $170!
Did some comparisons to the Nikon 18-200 and, while this is missing some features (anti-shake, a little lower f rating at the zoom end, etc), it’s really hard to beat for $170. Image comparisons show this lens, while not quite up to the Nikon, were excellent. It was on par or better than my Nikon 18-70. Focuses well and is relatively solid in build.
