Free Palm Depth Of Field Calculator

Finally! I've been looking for a simple and free Palm OS depth-of-field calculator for photography. Well, I haven't been looking that hard, but every time I search I come up empty, until I found this thread at Rob Galbraith's forums today which lead me to DOF Master. Very nice, and they have already calculated COC values for a number of digital cameras.

They also have Windows and online calculators. Bravo!
