Have decided to go for a 70-200 f.4 Lens. Have not heard one single word said against it. The problem is now there is the new IS version coming out which is the one to go for in your opinion? The lens can be handheld easily so is IS really a must? Warehouse Express have it up for £990! I am happy to pay the extra but wondered if it would be that beneficial. The lens will be used for travel and everyday use. Also would the USM version come down in price now there is a newer version coming out? :h?:
