Query: Tamron AF 75-300mm for Canon Rebel XTi DSLR

We bought this lens for my wife's Canon Rebel XTi DSLR. The 35mm film equivalent of this 75-300mm lens is 112-450mm.This lens is outstanding in every way. It has great build quality and a nice ergonomic feel. The focusing is pretty fast and it is able to autofocus accurately even at low light situations. It produces sharp pictures at all focal lengths with excellent detail and color balance. The lens hood is an added bonus.At this low price for a lens I looked for flaws, but could not find any. I have to agree with the other reviewers that the axiom "you get what you pay for" does NOT apply to this lens.
