The rear-end mount is Sony (and must be due to the flange focal distance needed to insert the adapter). Available at hcam.de.
IMPORTANT NOTE: Hartblei lenses are now sold by Stefan Steib of HCam.de; here is the story on HCam.de Hartblei lenses and other products.
Stefan Steib of Hartblei says the following (but also says it is not made by Hartblei, he is just describing it). I have not confirmed the claims on shift capability, quality, etc—informational only.
The HCam Master TS V2 can take about most lenses on the planet to shift and/or at least tilt them. Another version works with the Nikon 14-24mm f/2.8G. The Zeiss Otus 85 can shift a full 15mm.The Otus 55 has a pretty small image circle and is less appropriate.
The 11-24mm is actually a milestone I would say. But it is also very expensive. The Canon 16-35mm f/4L IS is kind of a workhorse for people who need to be fast, like realty sellers, hotel photographers, etc.pp. Being able to zoom in that wide range (and of course you can also still use the 16mm as well (with maybe 3mm shift) is speeding things up incredibly.
As shown above, the quality with such a shift is dubious: I did not find in my review of the Canon TS-E 17mm f/4L that it could support a full shift even on the 5D Mark III with more than marginal quality at full shift at f/11 (I have not posted all my results, so I say that based on additional work I’ve done with the lens since my review).
