I have read quite a few reviews on the Tamron lens and the Sigma lens mentioned in the subject line. However, I am not sure which one to choose from. They both seem to offer a good value or should I say versatility. My camera is a Canon 40D and I do have a Canon 28-135mm IS USM and a Sigma 10-20mm lens plus a Canon 50mm f/1.8.
