oh ya ive seen that before, and I know infinity has that "double zero" symbol look at the end of the scale, I just dont understand how one focus setting is good for all the situations i mentioned?
because the smaller your aperture, the bigger your depth of field (in-focus region)
focusing to infinity (eg horizon & beyond) will not bring your entire shot into focus unless you are also using a small aperture (above f/16 for example)


dont know how rough Sydney Harbour is as never been before....
