I would like to know more about this too. So if the OP can share more info, or if anyone else can share I would really like to know more.

Hi
I am very much interested in talking to a Canon Lens which I'm going to build into an Astronomical Spectrograph, so any information you can send would be fantastic.
From your username it sounds like you are an astronomer too

look forward to hearing from you

Ken Elliott

This is getting interesting, with real applications.

Need to get aperture control figured out. There are some 'dumb' EOS>Leica M adapters out there. With Live View, the new M/240 would be a great match for TS-E lenses (and telephotos), but getting these lenses stopped down 'manually' is a pain (requires EOS body, and yanking the lens off with DOF engaged).

Looks like Metabones has it figured out, with a EOS > Nex adaptor (that handles AF and IS functions).

Curious how the stop down control works.
