Question: what kind of warranty does it have and from who will it be honor with?
Document: What more is there to say. If you're looking at these reviews you already know this is one of the most awesome lenses on the market! - Came with full 5 year warranty from Amazon.
This lens also makes me move around a bit to be more creative vs. just zoom in and out. * AF-S 24-70mm f/2.8: I use this when I just don't know what kind of pictures I could be taking and need to have zoom & I don't have to move around as much.
(read the Pro statements above) - the negatives that people talk about is actually about themselves. Lens too heavy? go work out! lens too pricey, save up for it! some kind of a technical mumby jumby i dont understand non- normal word usage jargon - i refer you to 1-800-Geek squad, and you can talk to them who has a what and a what.
Expensive but I know this lens will last a lifetime. I can't add to what others have already written, sharp, weather sealed and backed by Nikon's 5-year warranty. I must in any bag.
Photojournalism (I use this term to refer to people shots in and around a city) would be a challenge with this lens. You can see this thing from a mile away and everyone begins getting self conscience about it. On the other hand a simple 50mm 1.8 or 1.4 is my preferred lens for that kind of photography and it does not give me the flexible zoom range that this one does.Conclusion:This is the best lens I own.
Alot of people complained about the distance with this lens and what not. This is my first telephoto lens of its kind (compare to the 55-200mm cheaper lens) and I like what I see. I'm okay with the fact that you have to be at a certain distance and its not a problem that unlike the previous 70-200mm 2.8 vrI where it had more range when focusing at certain distances. This is fine for me and I see more of the good things that bad.
when at 200mm at infiniti, it will be about 200mm. when focused as close as possible, the zoom range shrinks slightly. BUT this should only help, since it won't make a big difference if your trying to do macro or a close face shot. It also makesIf you want it, buy it. Its worth every penny. ( I only wait tables so i don't make that much money so im extra careful with purchases)DO IT
use this 90 percent of the time. Heavy but you dont need a tripod,  Krystal clear image. Great on dx and fx
under low light.
the fact this lens is constant aperture at f/2.8 even at 200mm means you can get some absolutely insane and glorious bokeh / depth of field effect / separation between foreground/background, and really makes your subject POP* the construction and handling is top notch, and despite it being the heaviest and biggest lens in the Nikon triple threat (14-24, 24-70, 70-200), it has the best feel.
Answer: If it is gray, forget about it. If it is USA, up to 5 years from Nikon USA with proof of purchase from an authorized Nikon US dealer.
