RF 800mm f/11 and R-series cameras

Hi

As you know, Canon will introduced this lens soon. Like everyone, I was surprised of f/11. However, looking back at capabilities of RP, f/11 is probably not a surprise:

"4,779 selectable AF points (143 area divisions for auto AF) with 88% horizontal and 100% vertical coverage supporting up to f/11 max apertures"

It looks like AF @ f/11 on Canon mirrorless cameras is similar (if not faster) to AF @ f/8 on Canon DSLRs.  Can someone who have used 1.4x & 2.x on EF telephoto lenses on either R or RP comment on this?

Thanks

Duy
