Thanks guys.
But I can't help but wonder if there isn't too much overlap between the lenses I already have. I mean, between the 5D and 30D, the combo 17-40 and 24-105 cover anything between 17mm and 168mm.
On the other hand, the 70-200 can cover anything between 70mm and 320mm on those camera's and upto 448mm with a 1.4TC.
Maybe I should sell the 24-105, but it's such a nice walkaround on the 5.
Ahhh... see? I am driving myself nutters.
