Looking to get into more landscape / cityscape / nature photography. Until now, I've mainly been using my equipment for indoor events. I've been reading John Shaw's books to familiarize myself with outdoor photography. He seems to emphasize telephoto lens just as much as wide angle lenses.
As far as wide angle lenses go, I'm probably going to go with the EF-S 10-22, as I'm committed to staying with my 30D at least another year. Beside that, the images I see from that UWA are stunning.
As far as the 70-200 lenses go, I'm in a bit of a quandary. The only one I have had experience with is the 70-200 f4 IS, and it is indeed an amazing lens. I haven't had much time with the f2.8's, but I definitely see the value of the extra stop of light in the 24-70, as well as excellent bokeh.
I'm limiting myself to around $1700 on this purchase, so should I get the 10-22 and the:
70-200 f4 IS
or save up and get the 70-200 f2.8 IS
