Has anyone got/used this lens? Opinions..... Please? :hugs: I want a fast lens with a good zoom for outdoor action shots.... cars/some aviation etc... will this do the trick? If not what is recommended around the £300/400 mark? I'm sort of guessing that for a lens that will really suit what I want I should be holding out for the likes of the EF70-200mm f2.8 L for the fast autofocusing? I dont object to saving for a little while.... Sorry for the bazillion questions... I'm lens baffled no matter what I read!
