Maybe, maybe not. On the left is a shot cropped to the FOV of 17mm on your XSi (27mm equivalent on FF). On the left is the original shot at theequivalent of 10mm on your XSi (16mm on a 5DII).

Both are nice shots, I think, but they tell a different story. Especially in tight spaces, sometimes you need that ultrawide. In the temple above, there wasn't much room to back up and achieve the shot I wanted (i.e. a shot without a crowd of tourists in the foreground).
