I am convinced, I sell the 70-200 I, and I buy the 70-200II. As you said Bryan the version I is one of my favorite lens, and I was waiting for your review to decide. I tried to compare the 135 f2 on the ISO12233 Chart, both at f2.8, I have the impression that the new 70-200 is as sharp as the prime. Am I right?[:P]
