It weights in at 2.84 lb. So even if you don't get good pictures with it, you will at least build your upper body strength carrying this beast around.
This week, I got my first opportunity to use this lens. The occasion being the Independence day celebrations at the Indian Embassy. The lens was perfectly suited for the occasion. The zoom range meant that I could take portraits such as this.

At the same time, the wide aperture allowed me to throw background out of focus. Even when the lens is kept wide open at F2.8, it is beautifully sharp.
At $900, this is not a cheap lens, but at the same time, it is the best bargain Nikon has on offer for this range. The other alternative is the 70-200 AF-S VR which costs almost twice as much (approx. $1700). Optically, both lenses are about the same. The more expensive version provides faster and silent focusing, and the VR (Vibration reduction) features means that you can shoot hand-held, which is very difficult with my lens. My solution is to use a $70 Manfrotto monopod, which gets the job done.
