Tamron or Sigma

[keybq]

well i just got back from the local camera shop they had the tamron one.I tryed it on my 40D and well it kills my old lens so far thats a plus i am still looking for a shop to try the sigma. But yea thanks for all the help. And the tamron did not seem that bad. Now if the sigma focuses even faster than that i will be amazed.

It will blow your socks off if you think the tamron is fast.
