I purchased this lens few months back because I wanted something light while travelling.
I normally used to travel with the Nikkor 17-55 and the Nikkor 80-200. The problem with this setup is:
a) I lose the focal range from 55 to 80mm
b) The combined weight of both these pro-grade lenses is more than what I lift in the gym during my daily workout.
In this respect, the 18-200 is the perfect travel lens. You get all the range that you would need in a small and light package, and you don't have to worry about changing lenses. The VR (Vibration Reduction) technology works as expected allowing hand-held shots at low shutter speeds of upto 1/15th of a second (a bit lower if you use proper technique).
It has it's disadvantages obviously. It a pretty slow lens with max aperture ranging from f3.5 to f5.6. This means, that when the lens is extended to it's full 200mm, the max aperture is f5.6 which makes it difficult to focus - plus the fact that you need good lighting to get useful pictures.
But even with it's limitations, this is the lens I will be packing for all my future travels.
Until I upgrade to a FX format camera body.
