Thanks for the link.
I figured that the mount was compatible technically speaking. However, what I am really interested in is how *well* it works. (at the end of the day, there are many adapters that technically work to adapt EOS lens to Sony... but the quality is wildly differeng).
I wonder if MC-11 would at least by comparable to the metabones in terms of functionality etc. to convert an EOS lens to A7rIII
