Hello I was wondering what people's experience with the EF II/III vs RF 70-200 F2.8L especially on the newer R5 body. Is the AF any better in the RF? Any noticeable IS difference? I already have the EF II version, but with my R5 wondering if it is worth the upgrade or not. I dont care about the weight difference, really focus speed, IQ are my key drivers. Thank you.
