It's true that the 17mm isn't as sharp as the 24mm, but the 17 is the sharpest of Canon's UUWAs and it is more than adequate. Sharper than the 14mm and much sharper than the 16-35. You won't be disappointed. And for a rental fee of 1000, it makes sense to buy it outright. I've heard that the Ziess 15 might be a tad sharper, but I've never tried it, and at those focal lengths, I'd rather have the movements anyway.
If you're using the movements to fix the perspective you won't have much freedom to stitch, so a wider lens is more useful in this case. If you need to fix the perspective at 24mm, try using the extender. I've never shot with the extender but have verified that it fits. In the end, you'll likely end up with both ts-e 17 and 24. =)
Yes, the 17mm seems to very sharp and to be able to use it on a landscape might be very useful I think. And for interior. With the 1.4x I can achive the 24mm aswell, but maybe not as tack sharp as the 24 TSE itself. But sharpness isn't everything and on that level I can do some post-sharpening aswell I think.
The Ziess 15mm, that isn't a Tilt Shift though?
