Question: I am looking for a lens to take outstanding swimming pictures. In general the light is bad and I am far away in the stands.  Will this lens work?
Document: I tried the lens on two D300 camera bodies with the same results.The only thing I have noticed is that the lens doesn't fit as tight as the DX lens in the mount on the camera.The Nikon DX 18 - 200mm lens that came with the camera works like a champ.Update:I ordered another lens from Amazon and I'm pleased to say that after 500 pictures the lens is still working like new!!!! Maybe it was a bad lot but so far so good!
I've had this lens for about a month now and have been getting used to it. My initial impression is that this is a phenomenal lens that is living up to its reputation and other reviews. The quality of the portraits I took with this using a D90 is super sharp and one of the best ones. It is actually difficult to take bad pictures with this lens. I am waiting for my D800 which should arrive next week and can't wait to try this on that body.
You still have to nail your shots, but when you do, they look better with this lens than virtually all of my other lenses (which in fairness cost much less than this one). About the only bad thing I can say is that it's not something I use all the time and it's very heavy (but if you're looking at one, you already know it's heavy). It's a fast lens and it focuses fast, even in low light.
That's what I call this lens. I'm an amateur, so I feel as though I shouldn't be reviewing this. What I DO know is that every time I use this lens, the pictures come out looking so much better than with my kit lenses. I have subsequently moved to full frame (D800) just to take advantage of it, and haven't looked back. I am glad to have purchased this one.
Looking forward to working this lens,  Initial thoughts on first pictures is that the lens is fast, in low light with good DOF.
Since this is new, this lens will be a keeper for a long long time....I am amazed at how the drifter gave one star to this outstanding lens.......if you look at the many 5 star rating on this lens...I wonder if the drifter got a bad copy of what?????? This is one heck of a lens period! !
Nikon on the other hand, that's 2/3 strikes, with the first being the D600 dust issues.UPDATE 07.31.13Well, I haven't had any problems since the first lens I received and can conclude it must have just been a bad case of luck. The lens I currently have is outstanding and can't imagine not having this lens in my bag. I love the focal length and the sharpness of the image, even while shooting in hand.
This is by far one of Nikon's best pieces of glass. Superb quality, and outstanding performance. While a little heavy, it's by far the best zoom for my Nikon. I paired it with the TC 17E teleconverter, and WOW! All I can say is &#34;Buy this lens&#34;!
I called the local Nikon Dealer, asked him about this lens and expressed my concern that it is not really a 200mm from near distance. He said "that is the bloggers saying. This is an outstanding lens if you can afford it"  Knowing about the reviews on Amazon and assurance from the local dealer, I bout this lens. Tested and compared the reach with my 75-300 lens at about 9 ft.away from the camera. Sure enough, it is about 150 instead of 200.
It is expensive, but if you have the money, get the lens. If you decide like I have to upgrade to an FX format camera this lens will serve you well.Here is my biggest recommendation, if you are going on Safari, 300mm is about the SHORTEST lens that will work. I found myself wanting more OFTEN. I would recommend going to 500mm if you are looking to shoot wildlife.
Answer: This is an outstanding, fast lens used by photojournalists, sports photographers, and enthusiasts the world over. It is one of three zooms carried by nearly every Nikon-shooting professional. it would depend on several factors: your camera body, is it APS or Full Frame, what is it's resolution (if you want to crop), and how well does it control digital noise at high ISO. Also, the actual distance you are from your subject. This lens should meet most of your expectations. If it doesn't, you might need a much more expensive, longer lens, say a 300mm.
