I bought a Kipon tilt-shift adapter to use with my Nikon lenses on my Fuji camera. Unfortunately, this adapter only had base tilt (instead of axis tilt), and only has lateral shift instead of rise and fall. Like old Nikon tilt-shift lenses, you can't rotate the tilt and shift axis independently, but unlike the old Nikon tilt-shift lenses, you can't modify the adapter to tilt and shift (rise) in the same direction.
This is bad. If you do base tilt, you also do some shift, which you then can't shift back (rise) to get back to the original composition.
If you plan to keep the sensor plane perpendicular to the ground, I don't see how you can use this system with tilt. I think it's impossible.
If you plan to tilt the camera, you can use the system, but it's a monumental PITA. First, you'll get converging lines and looming, so better get used to that, but worse, you can't compose. Each time you tilt the lens, you change your framing, and then you tilt the camera to compensate, and then need to tilt the lens again. You get an ambiguous composition, and it's very hard to achieve critical focus. At least I can't seem to do it (but I find it very easy on a real view camera with axis tilt).
Any tips?
