A very nice purchase Roger.
The 24-105L is one of my most used lens, very very handy lens and great quality for the zoom range.
I've heard a lot of great reports about the 100mm Macro, another great lens.
I've got the 180mm L macro and love it.
A good macro lens in the kit is essential and you've made a great choice.
Let us know how you go with the 500D !
