I use this lens on a Canon 50D. I am very pleased. It is sharp and unsharp at the moments i do want it. No problems with back or front focusing. just a very nice lens and better then the canon 28/1.8reviewed September 25th, 2009 (purchased for $543)

5 out of 10 points and not recommendedAffordable, nice IQnot sharp between 200-300, very inconsistent focus accuracy
The Tamron 70-300 performs very impressively well for it's price point. But between 200-300mm the performance is not good at all and does not match up to the competition.reviewed April 20th, 2011 (purchased for $389)
And it is my opinion that my Tamron 70-300mm f/4-5.6 Di VC Lens has a very inconsistent focus accuracy.Making pictures is good when its focus right, but a sharp lens does not deliver sharp subjects if not focused accurately.
