I am heading to Beijing next month. First time to Beijing, and probably the last time, that's why I don't want to miss any good shots.
Let's get straight to the point, I have the 40D, 24-70 f/2.8L and the 580EX II. I am just wondering if the 24mm will be too long for scenery? Do I need an ultra-wide angle? If so, (as you can see, I wanted one already:oops, which lens: Canon 10-22 or Sigma 10-20?
edit: I am also eying on the Tokina 12-24, too. Just wonder if 12mm is wide enough for scenery?
