I bought my R5 4 years ago and still haven’t got an RF lens yet , just haven’t felt I needed to
My most used lenses at the moment are EF 300 2.8 mk2 and Sigma 150 macro non OS had both of these a long time
The Sigma is an amazing lens so sharp and gives an excellent out of focus background as is the 300 2.8
Even if I had the budget, for what I do at least, I can’t see any reason to upgrade lenses to RF and as far as I understand there isn’t an RF equivalent anyway for these lenses, could be wrong haven’t looked into it to be honest
I read that the Sigma 150 non OS macro is not compatible with the in camera focus stacking (or bracketing) on Canon R cameras but it works absolutely fine on my R5 focus is completely accurate
