The Canon EF-S 18-200mm f/3.5-5.6 IS is a compact, lightweight super-zoom lens for use exclusively with Canon's APS-C format DSLRs, on which it offers an equivalent focal length range of 29-320mm. It features an Optical Image Stabilizer for up to 4 stops of effective correction, but disappointingly its USM focus motor is of the micro-motor type, so full-time manual focus is not possible. Although this is a decent lens which offers undeniable versatility, those seeking the ultimate in technical image quality should consider third-party alternatives.

This lens has to be accepted for what it is: a general purpose solution which allows the photographer not to worry about fiddling around changing lenses when out traveling, but which makes inevitable optical compromises to achieve this goal. The superb image stabilizer extends the capability of the lens still further, allowing you to keep the lens stopped down to optimum apertures for longer as light levels drop.
Good for: General-purpose use, such as travelling, where the wide zoom range and effective image stabilization combine to give a very useful package
Not so good for: Critical work, where the compromises necessary to maintain the zoom range become clearest - particularly CA and distortion.
