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. Less

Optically sharp, but focus errors at 200mm on distant objects

by tcchou71 , Jul 2, 2008
Pros: Small, compact. Good optics for such a wide range.
Cons: Soft corners at 18mm wide open. Canon version must be focused parfocally above 135mm.

This reviewer recommends this product.

Review: Epinions doesn't allow embedded photos, which is a shame for camera/lens reviews where the photo is the final product. Hence, I've posted a photo-enhanced summary of this review on my Geocities site:

Good, depending on what you want to do with it

by tesimpson , Mar 12, 2007
Pros: Lightweight, one lens for everything, good warranty
Cons: High zoom length causes fuzzy pics, frequent vignetting if aperture set by camera
This reviewer recommends this product.
Review: I purchased this lens a few months ago, because I wanted to have an all-around lens that would work with my Nikon digital SLR camera. The pictures in the mid-range to wide-angle (18mm-150mm) came out wonderfully. The pictures were sharp, no visible...
