I got the lens last week, and I'm not quite positive about it. Neither do I hate it. I want to mainly shoot wide angle panoramas, and I had high hopes that because of the shifting, my later stitching would be a snap, without having to correct frame-to-frame distortions. I already have previously overcome the parallax error by using a custom L-shaped piece of steel to have any lens' optical center on the center of the tripod, and not the camera on the center of the tripod. I'm sure my words are not right, but you understand..Of course with the TS-E I don't need that custom piece.
Anyhow, since a TS-E lens should naturally overcome parallax errors (right?), turns out it doesn't fix the problem of the lens-specific distortions.
What I want to say is that at 24mm, the lens obviously has barrel distortion. That distortion screws up stitching. (What to do?)
BUT, out of maybe 7 trials, one panorama was just fine.
I now don't know whether I should return this lens, and maybe get a 45mm TS-E instead.
If this is too naiive of a post, I apologize, but I tried researching the lens online, and found little info, and of course found no original size panos to check for it's distortions.
Can you spot any stitching errors in this pano? I didn't have to make any corrections here:

(HUGE FILE WARNING)
I also had to underexpose the midlle shot (out of three)..
In general, does anyone know of a good resource concerned with ts-e lenses?
Thanks a lot..
