Summary: The lens is great, once I got it somewhere else. Be aware that Amazon might send you a lens that has been used by another customer, then returned for being defective (or whatever reason). The first one I ordered arrived and had obviously been opened and handled. The Nikon box had been cut open and retaped closed. The plastic around the lens had also been opened. So I called and requested a brand new, unopened replacement. They assured me that they would send a new one.
Summary: I have hesitated using this glass because we have 400mm 2.8 pool lenses that I've always used. I've either been too tight or too loose, but the frustration is being too tight. You can never crop out, of course. So recently I've started looking at different approach to shooting. During our first post season series in Arlington, I chose to grab the 200-400mm, instead.
Summary: I have owned this lens for a few months now. I still am amazed at how clear and crisp the pictures are. I have had the wonderful opportunity of photographing NFL teams, many local high school teams, and the United States Olympic Wrestling Trials in Iowa. The clarity of the pictures made me look so good.
Summary: I have had this lens now for about 4 weeks. I use it for wild life photography in Rocky mountains. I also use the Nikon 80-200, 80-400 and Sigma 50-500. This lens is as sharp as the 80-200 but with much better reach. First and foremost the lens dose what Nikon claim it dose. Here are some things to think about if your considering this lens. This is a large and very heavy lens. and it gets heaver as the day goes by.
Summary: The 200-400mm is sharp, fast to focus and great vr. Many people say that it is heavy, well is heavy, but not too heavy that made impossible carry in a hand hold. I walked 6 km with this lens on my hand, also in a rainforest, here in Brazil and don´t get any problem. I have a tripod for the 200-400mm, because the wildlife photography have some moments that you stay in a place for several hours, and this is a sittuation to use the tripod.
Summary: This was a lens that I had decided to purchase for a long time after several recommendations from other photographers. It is fast glass! Accepts Nikon teleconverters (current series only) and has a built in filter holder. Holder is same size as the 600 mm lens one and therefore you can interchange filters, including the circular polarizer. It is large and heavy but reasonable sharpness obtained with fast speeds when handheld and with VRII turned on.
