Summary: I purchased this lens for my new 30D after being happy with my Sigma 28-300 3.5-6.3 on my Pentax K110. Got 25 test shots out of it and was really excited about what I saw. Got to the field for a game and it quit focusing in AF and MF. Sent it back and spent the extra for a Canon L.Now I dont want to spend the money on a 24-70 2.8 Canon L, so I am looking at the Tamron since I've lost faith in Sigma.
