This post is too funny. I just posted something similar the other day with the announcement of the Sigma 120-300mm! I want to see the Canon 70-200mm f/2.8L II w/1.4X go up against that Sigma. Put all three in one review and it would be very interesting to see all of the results!!!!!!! (In this case I am betting on the Canon kickin some %&@!!!!!!
