2-3 fps (with AF tracking) is woefully inadequate, people complained about the 5DsR's 5fps, but it was workable most times and was better than the 5D3 for AF IMO. 2fps is great for pelicans in flight I guess or resting pigeons. Even the M6II will be a far superior tool for BIF and action.Thanks!
I see the question mark so I suppose there's a question but I'm not sure I understand it:
"Is the best way to view the R with firmware 1.4 that it will equal or exceed 5dIV AF in every aspect with the exception of small, fast moving object that are impacted by the delay of the EVF?"
If you are asking about the AF accuracy compared to the 5D Mark IV I think the EOS R is better. I realized that with this camera it's either you get the shot in focus or you don't get it at all. There have been very few shots in so-so focus.
The speed is not that great but it's enough, even for sports and BIF.
