Too bad for everything at 4920 feet distance :-)
(As always, some calculations end up too precise - some clever rounding of
the figures wouldn't hurt)

Neat calculator. Now I know the hyperfocal distance of
my 600mm at f4 - it's 9843 feet.
So with a simple twist of the focus ring, I can get
everything from 4921 feet to infinity in focus.
No wonder the moon looks sharp, even at f4.
