I purchased this lens after my old one jumped down the stairs(don't ask). Basically, most of the previous reviewers have it bang on. It is a good solid telephoto lens that is ideal for most general uses. At this price you cannot go wrong. If you intend on photographing serious wildlife with dim light or extremely fast sports then you probably realize a more expensive VR (stabilization) lens would be what you are looking for. I shoot air shows an it is great for that. Also, with my D80, a DX machine the 70mm makes a nice portrait lends as it is light and not too intimidating for the model.
