My main concern is AF accuracy after my experience with the 70-200 is ii. Unlike my Sigma lenses that are pretty much perfect, the Canon is not, when it comes to consistent tack sharp focus.

FWIW, I moved from EF 70-200 f2.8 II to the RF 2.8, and what I observed was:

  • RF is lighter, compact and handles better. f4 should be even better
  • AF accuracy was similar, speed RF is slightly better. The relevant point here is that I didn't see accuracy problems with EF lens on R5 using Canon control ring adapter
  • RF IS is better
  • focus breathing isn't something that bothered me for stills shooting. Can achieve same magnification and in fact prefer shorter MFD. This is something people will have different views on.

Personally, I don't know how the f4 lens compares
