Opinions?: Tamron XR Di or Sigma 28-300 for Dig Rebel
Just looking to get a decent TOPSIDE lens for general use, but there are few opinions on the Tamron XR Di, and some that I've read saying the Sigma is cheaper ($100 less +/-)and has better optics (and metal lens mount).
Just looking for any points of comparison, and my expectations are in line with the price range the lenses fall in.
Thanks for your input.
