I have the current 100-400mm f/4.5-5.6 L and love it. With a new version coming out I'm thinking of upgrading to it. But how should I go about that to save the most money? Do you think I should sell off the one I have now a month or two before the new one is released and then buy the new one? Any thoughts how how different the new one will be?
