Re: the adapters, image quality doesn't deteriorate. However, autofocus is nonexistent for the inexpensive adapters, and from not great to not working on the expensive adapters. Also, if your lens doesn't have a manual aperture ring, the cheap adapters won't let you set the aperture (or, for the G lens adapters, will only let you specify "more open" and "more closed" as opposed to setting a specific aperture). I use an adapter with a Zeiss zf.2 lens and it works great because I don't need autofocus and the lens has an aperture ring.
So far, all the test of Canikon WA zoom I have seen perform worse on Sony than Native. I guess the most WA zoom funky enough cross range even for native system, any variables just make them even worse, but I have seen many report with the exact same lens test on 5Dsr (or D810) and A7RII, and always perform 'significant' worse on Sony, this eliminated copy variation possibility.
