我而家用緊40D+17-40 f4 想買24-105
如果放17-40來買24-105會唔會浪費呢?
定係努力儲錢買24-105呢?
之後我都會買70-200 F4

你賣咗１７﹣４０mm，咁冇咗１７﹣２３mm嗰段，２４mm用喺４０D上唔夠wide喎。

Keep 17-40, and buy 70-200.

17-40mm is wide angle Len
24-105mm is standard zoom Len
That are totally different Lens.
I also prefer you keep the 17-40mm and buy 70-200mm f/2.8L
