Using the hyperfocal distance of the lens, possibly modified, to make
sure that everything you're likely to shoot is in focus.  For example,
take your lens and figure out what f-stop you want to use.  The turn
the focus ring until the infinity mark lines up with the "tic mark" for
the f-stop you're using.  The "tic mark" on the other side of center
will tell you what's going to be in focus.  So, just to pull some
numbers out of thin air, you pick f/5.6. When you line up the infinity
mark on the focus ring with the "5.6" tic on the barrel you might find
that the opposite tic indicates 10m. That means everything from 10m to
infinity will be in focus.  So you don't worry about focusing unless
the target is closer than 10m. You can shift it closer if you're not
worried about things at "infinity" distance.
