Looking into Tilt-Shift 35mm Lenses

I'm intersted in understandingthe benefit of Tilt-Shift lenses in panoramic photography and have found some interesting links. The DOF control looks fabulous with Perspective Control (PC) lenses.

Here's the link list so far:

1. Roger Eritja's review of the Nikkor Micro 85mm f/2.8 PC lens.
2. Using the 35mm Perspective Control lens (Nikkor Lenses)
3. How Shift Lenses Change your Life (Photo.Net)
4. Some info on the Canon TS-E 90
5. Some interesting discussion on Canon lenses tahat talks about DOF issues as they relate to diffraction.
6. Some more context from Luminous-Landscape on DOF, again Canon Lenses
7. Nice example of the Nikkor 28 PC used to mimic 4x5 formats via Panorama at Photo.net.
