Have decided to go for the 70-200mm f.4 lens as I havent heard one single word said against it but now the IS version is coming out what do you guys out there think, is the IS version worth the extra money? I see Warehouse Express have it marked up for £990 that is double the price! And do you think the price of the USM only version will go down in price now this newer version has come out? It isnt a heavy lens and should be easy enough to handhold. The new lens will be used for travel and general everyday stuff. I am happy to pay out for IS if you think it is the right way to go
