Lord it will be used like a prostitute on pay day.There are better lenses yes but they cost ridiculous money, at that price point its bang on, fine piece of L glass.
One word of caution though, think very hard about the amount of use it'll get before you part with the readies, L series lenses are all well and good but if they're hardly going to see the light of day (groan) then I'd consider standard glass.
