Hey everyone,


Really quick, I am buying a f/2.8 zoom for my 50D and it's between the EF-S 17-55mm f/2.8 ISand theEF 24-70mm f/2.8L. I am 90% on the EF-S 17-55mm f/2.8 IS but the only reason I ask is because eventually I am going to upgrade to a full frame camera. The thing is that I can't say when I am going to upgrade so my thoughts are to buy what I need now and worry about the future later. Your thoughts???
