I came across where B&H compared the R5 to an number of different camera bodies and here where a number of Canon Explorers of Light, who have used the R5/R6, answer questions about them.
This is starting to answer my next main question, I am seeing a number of people commenting on how good the AF is. Speed/accuracy. Rick Sammon saying the R6 is going to be his "go to" wildlife camera...
No doubt Canon is behind the marketing getting advanced cameras to youtubers and EOLs, etc. But, I am seeing pretty consistent reports.
I should really get off the internet and go take pictures......
