All I said standard lenses have focus scale written on them, in total darkness you can focus to infinity by looking just on the lens barrel

focus by wire lenses don't have focus scale on them, some cameras like Sony A7 and surely many others show you the focus distance on the camera LCD and thus you can focus to the desired distance with the lens

Focusing to take this one  was a nightmare with 10-18 that focuses by wire, had t focus scale or did the camera write focus distance on the LCD things would have been much easier,, anyway I am not quite happy with the focus here, I should have focused a little further

  I don't know about focusing this and thats.........

 

       but that's a very nice image!
