Hey everyone!!! I was just wondering if anyone has had the chance to try out the EF-S 17-55 f/2.8 IS and what they thought about it? I'm looking for a wider lens to complete my set for now. Right now I have the 28-135 kit lens that came with my 50d, 50mm 1.4, and 70-200mm L f/2.8 non-IS. Thanks in advance!
