Tested with these lenses?

I would like to know if someone has tested with these lenses below:

- Sigma 300-800mm f / 5.6
- Tamron 70-200 f / 2.8 G2
- Tamron 24-70 f / 2.8 G2
- Sigma 400mm f / 5.6 (classic)
- Canon 50mm f / 1.2
- Canon 35mm f / 2 (classic)
- Samyang 14mm f / 2.8 (manual focus)
- Samyang 8mm f / 2.8 (EF-S)

I am interested in autofocus functioning as it should and is fast?

I have Canon 5D Mark IV and Canon 6D. I plan to replace Canon R against 6D. I want to know how these lenses work on Canon R. If the R pro version gets good then I will replace 5D Mark IV against R pro so maybe I sell some of my EF lens to get R lens.

Sigma 300-800mm f / 5.6 gets expensive to replace so I'm considering keeping it. An advantage of R is that you can use 2x converter to 800mm = 1600mm with f / 11. If it really works? If anyone here has tested?
