I have this lens on order myself and intend to do a full review as soon as I get it. Unfortunately there are so far no signs of it coming to Canada. In fact a Canon rep even said he’s ‘not expecting it this month’ which is somewhat worrying as B&H is expecting to begin shipping theirs next week. I have to buy mine in Canada to take advantage of my CPS discount otherwise I would have just gone with B&H. video via CanonRumors
