Thanks Patrick, that's reassuring to know. I was thinking of trying to find a Sigma 400 f/5.6 APO Tele Macro to go with the 70-200/2.8 EX and 300/4 APO but considering the weight I'd be carrying and the problems I have with teleconverters the Bigma is looking like a better solution. In reality the Sigma 300-800 would be great but funds won't allow. > My only peeve with the lens (and all sigma ex lenses) is that the > lovely sigma EX finish tends to scuff quite easily.
