Summary: If you want to get an ultra zoom, which despite their problems in quality arr useful if you want to carry only one lens, most people's first choice is the Nikon 18-200mm; if you can find one and afford it. The second is Tamron's 18-250mm lens.
Summary: After I bought the D50--my first DSLR--I went on the hunt for a good all-around lens. I was upgrading from a fixed lens system with 10X optical zoom, so I would settle for nothing less than a lens with 10X zoom equivalent.
Summary: Nikon has discontinued this lens, which is a shame. It is lightweight, sharp, and makes a perfect walk around lens for any full frame (FX) Nikon DSLR like the D700. I bought mine used, for more money that it originally sold for new. Ken Rockwell gives this lens very high marks.
Summary: This is an excellent general purpose lens. This lens is always on my D80 camera. Whether I want to shoot group of people close up or pull in a shoot from farther away, this lens will do it all. For longer shots I use a 70 - 300mm on special occasion, but normally I use the 28 - 200mm.
Summary: If you are like me, you really can't afford the 18-200MM VR Lens. Besides, the VR lens is sold out everywhere at this time. This 28-200 lens is really spectacular. Forget about people talking about barrel distortion, keystoning, etc. The images really speak for themselves.
Summary: This lens gets along very well with my N75. I wanted a versatile lens that could go from wide-angle to telephoto, and that is exactly what this lens does. It is also extremely lightweight, extremely sturdy, and produces that classic Nikon background blur.
Summary: I read about this lens in the Nikon D7100 guide by well respected No.1 Camera guide author David Busch. He described it as one of the best lenses he had ever bought. Ken Rockwell also sings it's praises but says it is superseded by Nikon 18-200mm VR.
