I have a Nikon 70-200mm f/2.8 VR and here is a review why these type lenses cost as much as they do...
click meTaken from
www.kenrockwell.comThe reason the 70-200mm VR costs ten times what other equally sharp lenses might cost are because the 70-200 VR also offers:
1.) Fast f/2.8 speed for low light, soft backgrounds and action-stopping shutter speeds.
2.) Built tough: all metal except for rubber gaskets and bumpers.
3.) Built to last: many markings are engraved to outlast all of us.
4.) Fast, quiet AF with a silent wave motor. You won't scare sensitive subjects as other AF lenses might.
5.) Instant manual-focus override: just grab the focus ring at any time
6.) Vibration reduction so you can leave the tripod at home.
7.) Three AF-Lock buttons to lock focus when pressed and held. These are extremely handy once you learn to use them.
8.) Better bokeh than most other Nikkor lenses.
This 70-200mm f/2.8 VR is one of the two lenses used by most professional photographers every day. The other lens is usually a wide zoom on a second body. <--- (This is the setup I usually do.. my D700 with the 70-200 f2.8 or a 50mm f1.8 and my D70 with an 18-55mm f2.8 )
