Go to solution. 12-29-2022 05:10 PM. I've got RF24-105 f4 L lens with R6. All's good and working as intended. However, I noticed when I customize control ring for exposure compensation, it's not working, all other options (ISO, Tv, Av etc) are working when I rotate the control ring except exposure compensation. .
