The focus wheel of the Harpia is according to specs and videos of dual-speed type, so at small movements you get fine focus, and with more turning it's faster geared. (there's a video with Jerry Dobbler from Zeiss explaining it in the thread)
But would be nice to hear about how it works in practice
from those who actually tried the scope.
