The Canon EOS R focuses with the aperture wide open; this is partially the reason why the EOS R does so well focusing in low light.

Most other mirrorless systems operate fully stopped down when focusing.

well - in low light every mirrorless camera will focus with aperture wide open - unless you force different aperture manually

Personally I found it strange choice but maybe its just me. I prefer sony's DOF preview implementation

There is a very big upside to the way Canon is doing this. The maximum amount of light is available for the AF system, so it also works in almost complete darkness. Not so with the other brands. Besides, why would you want DoF preview? I have never used (well, actually once to check if the button works) this function on my 5D.
