My two cents: I own an R50 as my knock-around camera. I was so surprised at how well the 24-105 STM pairs with that camera. I own the Sigma 18-50 as well because I did not like the build of the RF 18-150, and I don’t tend to go past 100mm in my photography. The Sigma lens pairs beautifully, but I need to be careful with the control ring, which is right next to the camera body.
I lived in Northern Arizona during my film days. I wished I had a wider lens at that time when I traveled to Utah’s national parks frequently, so I like Steve and Jim’s suggestions.
