I actually have a DOF calculator on my XDA/phone which calculates
depth of field and hyperfocal distance for whatever camera
body/sensor, focal length, aperture, and working distance you
choose to input. It's basically a Windows Mobile version of
http://www.dofmaster.com/dofjs.html

hyperfocusing for all that to be any use... :)
