This is absolutely stunning.
This is such a fantastic picture! Very sharp and lots of details. I viewed the original size on flickr. If you look very very closely, the right side of the picture seems just a bit softer than the left side, especially the statue thing (I don't know how to call it). Is this something that bothers you? Or, since this lens is so wide this is the limitation of this lens? I am curious because my copy does that too...
Thanks to everyone!
As for the softness, I think the technical review sites (Photozone and the like) show this lens drops off in sharpness quite a bit in the extreme corners. I don't find it an issue at all, because the lens is so wide that whatever is in the corners is already very distorted anyway.
In this case, I cropped a pretty big chunk off the left side of the frame to achieve symmetry so this wouldn't be a good image to judge left to right sharpness...
