>>3660082Muscle memory is definitely important, but it's also easier than that. You use the focus marks on the lens. Look up hyperfocal distance and how it works.
I use the same lens as you so here's an example. See how the the infinity mark is at 11 on one side and 2m at 11 on the other side? That means everything from 2m to infinity will be in focus if I set the aperture to F11. I'll park my lens like this and walk around snapping away.
