X 100. I have this lens and use it extensively for work, indoor and outdoor scene documentation. I am very happy with the quality of the optics and as a one lens does it all package. The VR function is very helpful, particularly when you don't want a flash in reduced light situations. I consider not having to carry around multiple lenses a plus and I don't have to worry about dust getting inside the camera/lens (major plus).
On the downside, it is a slightly larger/heavier then a lot of standard lenses (minor negative). Also, when shooting at significant downward angles, you have to hold the lens barrel to prevent creep (minor/major negative).
The lens is pricey and can be beat by specific application lenses, but for my use it was the best way to go.
