Still users need to dive into menu system to set options for that switch and as some one pointed out its apparently for better usability of beginers. Dont see how beginers who rarely change default settings or dive into manuals are going wrap their heads around this.
As a beginner, that ring is what made me want to understand ISO better and when to adjust it. Now I actually use it. The EVF lets me see exactly what’s changing, which is great as a beginner. Prior to the new year, when we purchased the RP system, I never took the ISO off Auto on my old Rebel.
Beginners who buy this system may be rather novice, but they are people who want to learn more and improve their photography.
What I don’t do a lot of is manual focus. I’ve tried, but with the new touch drag auto focus, I don’t trust my eyes as much as this cameras. I used it more on the Rebel if there were foreground objects with my subject standing back. Now I just move my focus point to my subjects face, back button focus, and shoot. My miss rate has gone way down.
