The pictures below illustrate the focal length range from wideangle to telephoto:

Huge 11x focal length range; ideal general purpose and travel lens; Excellent image stabilization system; consistently delivering three to four stops benefit; Good central sharpness at all focal lengths (but inconsistent corners; Attractive rendition of out-of-focus regions of the image; Improved...

Poor sharpness across much of the frame at 18mm and wider apertures; Pronounced barrel distortion at wideangle; and pincushion distortion around 50mm; High levels of chromatic aberration at either end of the zoom range

Huge 11x focal length range, ideal general purpose and travel lens ; Excellent image stabilization system, consistently delivering three to four stops benefit; Good central sharpness at all focal lengths (but inconsistent corners); Attractive rendition of out-of-focus regions of the image ; Improved build quality in comparison to the 18-55mm and 55-250mm kit lenses; Well-placed zoom lock switch ;

Poor sharpness across much of the frame at 18mm and wider apertures; Pronounced barrel distortion at wideangle, and pincushion distortion around 50mm; High levels of chromatic aberration at either end of the zoom range;

Designed to provide a wide zoom range in a compact and lightweight form factor, Canon's EF-S18-200mm f/3.5-5.6 IS telephoto zoom lens can only be used with cameras that have 'APS-C-sized' image sensors.

This is an excellent all around lens (vacation lens). I bought this as a kit for my EOS 50D. As a kit lens I would say it's one of Canon's best kit lenses and very comparable to the cheaper 55-250 in IQ and performance. The build quality is what beats the 55-250 by a long shot.

Great walk around lens; Very sharp at 200mm; good build quality; quiet micro motor AF

Barrel distortion at 18mm; CA at 50mm range; slow AF in low light at 200mm

To sum up, the Canon 18-200mm ƒ/3.5-5.6 IS offers slightly better performance than we're accustomed to seeing with vacation lenses, with image stabilization thrown into a very portable form factor.

Canon is often at the forefront of technological advances but for whatever reason they are the last of the Mohicans regarding their entrance into this specific market segment. This is insofar surprising because these affordable "super" zoom lenses are THE hot sellers in the entry-level segment with...

The Canon EF-S 18-200mm f/3.5-5.6 IS Lens features an awesome focal length range (one that completely covers the needs of many photographers) and an excellently-performing IS system in a nicely-sized body.

I purchased this lense because I trust the quality of Canon products. I especially like the image stabilizing function on it. My camera and this lense are a perfect pair.

Durable; Good Value; High Quality
