This lens is cheap. Both in price and construction. With that in mind, it is a good product. Pictures are sharp, as the glass is of the typically great quality. The vr works adequately.

A really good all-around lens. If I had to take only one lens on vacation, this would be it. The combination of wide angle and zoom make it very versatile. Some reviewers have complained of lens creep - the model I received had a manual lock that prevented creep, but you have to unlock it every time...

The IS function works good as long as you're not over-caffeinated, I imagine a system built into the camera body works better though; Decent focusing speed and low-light performance; Great zoom and wide angle.

Heavy; Obvious vignetting; Obvious spherical aberration, Power consumption is high with the IS switched on, and ***the IS does not seem to shut off when you turn the camera off!*** I have to shut off the IS independently; of the camera power.

This is Canon's first foray into the superwide to telephoto class of lenses. It still needs some work As the title implies, this lens does a lot, too much in fact. It suffers from the problems associated with long zooms: pincushion and barrel distortion, and the edges aren't very sharp at most...

Just to add to a previous review - the zoom actually can be locked so that it does not extend when being worn around the neck - this makes the lens magnificent for a full days action. This is the favourite lens in my collection and normally is resident on the body for general use.

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.

A great walkabout and travel lens at a very useful focal length range, this one produces amazing pictures, needless to say. The zoom range is exceptional too. It also features a built-in Optical Image Stabilizer with automatic panning detection feature. A class Canon lens.

If you are not ready to post the review in your site then I will make a video of the faulty lens which was sold by canon e store with bill and details in YouTube and let people new the truth.

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

Being an EF-S design this zoom is one of only a handful of lenses in Canons range that is suitable for use only on APS-C digital SLRs. Buyers who might be thinking of upgrading to a full-frame body in the future could be tempted to steer away from this lens for that very reason but there is no...

I bought my 550D with the twin lense kit which included a 18-55 and a 55-200. I only ever used the 18-55 but then 12 months ago I bought the 18-200 lense! It is much more versatile and the 18-200 lense travelled with me all through the US and UK on a two month journey and performed wonderfully.

Superior build quality; Super-sharp images
