I have a Kipon tilt/shift for Leica-R on an XE-2. I tried using a Leica 28mm (ver. 1) and it works fine, though when fully shifted there's a lot of distortion on the edges etc. but that's expected.
Now I'm trying a Leica Zoom, a more recent lens from ~2004. It seems like a terrific lens, but there's something that impedes the adapter's shift mechanism, restricting the range to only half of the full range. Tilt range is not affected.
Has anyone encountered this issue? I'm wondering if the electrical contacts in the (more modern) zoom are getting in the way of the shift. I wrote to Kipon but no answer.
