I'll be visiting England and Scotland next September and need your advice on which lenses to bring. I don't want to carry too much weight, but don't want to miss photo-ops of a life time either. I was thinking of bringing my 40D with a 17-55 and my Rebel XT with a 70-300. I'm sure I'll need the low light capabilities of the 17-55 for inside cathedrals and such, but will I get much use out of the 70-300? We'll be visiting all of the usual tourist places like London, Stonehenge, Lochness, some churches and castles. Any help would be greatly appreciated.
