At 14mm you don't need to be worrying about DOF. Even at f/4 the
hyperfocal distance is just 7.8 feet. When the camera is focused at
that distnace everything from half that distance (3.9 feet) to infinity
is in focus.
At f/5.6 the hyperfocal distance is 5.6 feet and at f/8 it's 3.9 feet.
For a landscape I'd shoot at f/5.6 or thereabouts which is probably near
the optimal performance for the lens.
