I've heard that is THE lens to have. My friend wants me to buy one so she can "use" it. I already have a 70-300 IS, but the f2.8 is probably a better bet. Your 70-200 is an L lens, right?
Man that is the setup right there. If or when you decide to do a full wrap on that Xb that thing will be a full rolling billboard. Nice job :applause: on what you already have!!
