Don't forget TILT

Is there a substantial benefit to having a shift lens for a DSLR, as opposed to adjusting perspective in post-processing?

(Bonus points for examples!)

Aside from "shift", a tilt-and-shift lens also offers "tilt". This can be used to change the angle of the focal plane and affects the depth of field relative to the plane that your subjects reside on. This cannot be simulated with software. True that people have used gradient blur to approximate a reduced depth of field (the "miniaturization" effect), but the result is not quite the same. Impossible to simulate increased depth of field.

Tilt-and-shift lenses have the disadvantage of requiring additional setup time; more so if you're using tilt. This is not quite conducive to a grab-and-go shot.

BTW, the Canon TSE-17mm is an incredible lens.
