Summary: I purchased a used version and couldn't be happier. It was "used" a few times by a Nikon Professional Services Pro a half dozen times and arrived in mint condition with no signs of use. The Nikon soft case it came in was the replacement by Nikon because the original was recalled for problems. I put it on my D810 and it autofocuses with Nikon's latest versions of the 1.4, 1.7, and 2.0 teleconverters, contrary to the claim in the product literature.
Summary: This was my first super telephoto lense. I have used the 70-200 for a couple of years for indoor sports. This lense is crazy good. Focus is super fast and crips. I needed this lense for outdoor sports and a 2x teleconverter on the 70-200 just wouldn't focus or keep the light right. Now I know why these lenses call for a premium price. You get what you pay for and so far I have shot about 15000 pictures and love it.
Summary: The Nikon AF-S VR G 200-400 mm f/4.0 zoom is a pro lens by any means. You may also call it a "tool", so you should buy it if you have a job in mind for it. I bought mine for airplane and airshow photography. I have a Nikon 300 mm f/2.8 prime lens that I use a lot and it is excellent for me under most circumstances, but there are times when a fixed focal length lens is less than optimal. At most airshows the photographer's move relative to the airplanes is limited.
Summary: This is a large and heavy lens with lots of features. It appears to be well constructed. I have only taken a few photos with it, but so far it isn't as sharp as expected. The photos were taken on a tripod with very little chance of excessive vibration. The Vibration Reduction was turned on and the shutter speed was fast. The purchase price is a LOT of money to spend on something that doesn't produce perfectly sharp photos. I am using it on my D300 for nature photography.
Summary: I just returned from shooting the 2010 olympics in Vancouver. This lens ended up being one of my go-to lenses. Obviously versatile with a nice zoom range and plenty fast. Great at the nordic skiing venue and sliding tracks but also a nice slalom and GS lens. Very sharp, sharper at 200 than my brand new 70-200. I used the 1.4 converter on it and it looked great. Autofocus is fast if a little noisy/clunky compared to my 500 4.0.
An absolute jewel of a lens... if you only buy one long lens, it should be this one.

Summary: Conventional wisdom says that primes (lenses of a fixed focal length without the ability to zoom) have better optical quality than zooms, and that's almost always true. But in a few rare cases, zooms can be better than the available primes (see Nikon's incredible 14-24/2.8 for an example), and in others the difference in quality is so small that it becomes functionally irrelevant. So it is with this lens.
Summary: I absolutely love the lens. It's sharp thru out its entire focal range and is quick to zoom in on what ever the subject may be. I use it for shooting sports action, so it's the best lens I've shot with thus far...
