With the lens focused at a subject a certain distance away with a lens of a certain focal length and fstop, and a certain allowed CoC (circle of confusion), it will give you the near and far acceptable in focus range for that CoC.

Joe,
If you've not already done so, see the extensive "Ultimate DOF Skinny thread.

Also note that the Panavision calculator is designed to deliver results for prime lenses, not zooms.
