I photograph mostly people (in action and portraits) and landscapes, and since I bought my 5D II, I have only a 50mm 1.4!
Before I buy a 70-200 II or a 135L, I feel like I need a standard zoom, there's no way to run from it.
The 24-70 II is not an option for me now, sorry guys! I know I should buy it, I know, but I'll buy the 70-200 II for that money later this year.
(I could also buy a 135L and use it with the 50, that would be awesome for portraits, but I think I'd loose some opportunities if I had these two only).
