And Sony people get off the high horse. They dont work well with non Sony glass. Hit and miss 4:20....exactly what I have said all along
I'm not understanding this comment. It's a nice feature that Sony cameras work reasonably well with adapted lenses from other manufacturers. It's true that the performance is not as good as with Sony's own lenses, but it is still pretty usable in non-demanding situations.
Canon EOS bodies work in AF with precisely zero lenses made in other mounts. Ditto for Nikon. You cannot mount a Sony lens on EOS. You cannot mount Nikkors on EOS. These do not work at all.
If you don't find adapted lens performance on the Sony to be good enough for your needs, fine. But that's not a negative. It's a feature that it works at all. I do not expect the Canon R body to work with some kind of adapter that allows use of autofocus lenses in other mounts (Sony, Nikon, Fuji etc.)
