Hi,
HCamDE makes a T&S adapter for the A7 called Master TS (I think). It is based on the Mirex adapter design, but specific to HCam, it gives TS with all lenses.
It essentially offers T&S with a Canon bayonet, and almost any lens can be adapted to the Canon mount. It does not have electronic support for Canon lenses.
I have used my Canon 24/3.5 TSE on the A7rII quite a lot. My Metabones IV is broken, but works some times. I guess I am quite happy with the results.
Best regards
Erik
