After it was stolen, I "replaced" it with the Olympus Zuiko 35mm f/2.0 lens. I wasn't thrilled that I was introduced to barrel distortion. So I never really took a liking to that lens, and I kept thinking I should get the shift lens... not at all for the shift feature... but because I had the impression it was bound to be rectilinear.
It depends on how it was designed of course. One always hopes a shift lens is designed with architecture in mind, meaning it would be well corrected for distortion, but it depends on the lens. Take the Nikkor PC-E lenses for example. The 85mm and 45mm are virtually distortionless as expected (particularly in the 85mm focal length). The 24mm has visible barrel distortion near the edges. The Canon 24mm TSE-II on the other hand has virtually zero distortion.
