I saw Tamron has more rebates out right now. Got my first one on rebate...this makes it enticing to look at more toys...

Just chiming in as others have said--spectacular value; I bought this from Newegg over a year ago Along with a Canon T2i), and it is still performing flawlessly; It is a joy to use; The Image Stabilization (IS) is truly as good as everyone says it is.

It wasn't free

I bought this for my new D7000. pictures are very sharp even at 300mm and very great bokeh effect. I was considering the nikkor 70-300mm. But I am glad that I bought this. I borrowed the nikkor 70-300mm from my friend and compared this and nikkor. GO TAMRON.

The 70-300mm lens from Tamron offers a lot of zoom in a reasonably priced lens, delivering sharp images.

Near-silent autofocus; Very good image stabilisation; Sharp images at shorter focal lengths (70-150mm

Zoom movement is very firm; Unattractive bokeh
