It's a great lens. I really like mine, but wish I would have gone for the 17-50. If I need anything near the 50 range, I have my 50 1.4, 85 1.8, or 70-200L that I'd much rather use. The only thing that pisses me off about Tamron is that they put their zoom ring on backwards! I hate switching from the 28-75 and the 70-200! They turn the wrong way!
