This is the textbook example of what the TS-E 17 is designed for: close-up photos of tall buildings.
Of course, that's not all it can do, and it's not all it can do really, really, well. But it's basically its primary purpose.
If you're thinking of doing this sort of thing -- or of similar sorts of close-up shots of very big things (including mountains and trees) where you don't want any geometric distortion -- then this is the lens for you. If you have other types of photography in mind, this probably isn't the lens for you.
I've checked my metadata and 50% of my pictures shot with the 16-35 are at the very wide end. I've added a few examples which I believe work nicely. I have not added examples which do not work because of falling lines. What I obviously try to do is frame at 16mm thus that the falling lines are as limited as possible. With the 16-35 this can lead to mediocre results due to corner unsharpness (see picture 8814 showing the limits of this 'technique'). Not all of these picutres are potential TS-E candidates, of course. Picture 3938 for example surely isnt... Again, all pictures at 16mm
