The focus scale written on the lens' barrel is basically also estimation - and the numbers, as well as the ∞ character are big enough to cover some distance. One needs to stop down three stops to hit somewhere close to bull's eye.

 

The Batis lenses do have LCD focus scale, together with a DoF scale. But you know what? You gave me kind of motivation to go out in the dark and cold night and see if the clouds are too dense to see some stars...  thanks.
