This makes NO sense to me AND it worries me a bit as the primary reason I went mirrorless was due to focus frustrations with long lenses on my 7Dii and 5Div. I desparately need to take the time to make MFA to both of them on my Sig150-600 ; EF70-300L. (They’re both perfect with the 100-400ii) but the promise of the R never needing MFA (it’s effectively monitoring the final image adjustment during AF, it can’t miss, right?)

Originaly I was buy RP for this reason too.

There is lot articles how dual pixel af works. In here an interview with Canon engineers from this. They tell R focusing phase detect only, and "enough" accurate.

In first round i think, my lens(es) is simple a bad sample. (But all this is a speculation.)

On my old 50d my 50 1.4 and 85 1.8 needs AF micro adjustment in pdaf mode. In Live View it was 100% accurate (50d LV is cdaf only).

On the first canon milc (eos m - hybrid pdaf after cdaf) 100% accurate.,

Now on RP - both - bad luck.

Maybe it's an little incompatibility with my lenses, or my lenses simple buggy (or the ef adapter). This lenses are very old constructions, EF 50 1.4 is introduced 26 years ago...

My RP with RF 35 1.8 perfect focusing. I don't think its a body issue.
