Hi,
any anyone tried using a 70-200 f/2.8 on a 450D?
i understand about the cropped factor of 1.6x on the 450D which makes it a 112-320? Just wondering will it be a good buy for that camera? or should i be looking at other lenses?
thanks

I'm ordering a Sigma 70-200mm f/2.8 tomorrow and I feel a little better about it after seeing your work with that lens.
