That could be true yes. I wasn't going by charts I suppose, but rather, experience. However, wouldn't that be amazing if it were sharper than the 24L? I still won't sell it because I shoot wider than f/2.8 with that lens. But if I can have the 16-35L, 24L, and 24-70L, that will more than cover me for what I shoot. Now, suppose we saw a 35L II and 50L II come out later. Boy, will Canon have a superb lens lineup by then or what, not that they don't already??
