Just wondering, is there a good Depth of Field Calculator for Pocket PC?

Description:
DOF is a program for photographers that computes depth of field of lens given its focal length, f stop, resolution and focus distance.
It reports the near and far focus limits and the hyperfocal distance (the minimum distance you can focus at and still keep infinity in focus).

Update Description:
Increased range of f stops, film speeds, and exposures

yup there is a model made by sharp for such calculation

but not sure what the model name is ;p

tat free software mentioned above is only for pocket PC right ? any free software available for desktop ?

I use f/Calc on my laptop as well as on my lab machines. There are 7 different "functions" on this calculator...

(i) Field of View
(ii) Angle of View
(iii) Magnification
(iv) Spot Meter
(v) f Number
(vi) Depth of Field
(vii) Hyperfocal Distance

Here a screen capture of this free software... I find it quite handy to have around.

The equations for the near and far depths of sharpness do not look too complicated. So, you can always compile a table or plot graphs for your camera's given circle of confusion and focus distance. Such a handy chart or plot is surely more handy than lugging a Palm Pilot? Kids nowadays are so spoiled, what do they know about pre-calculator days?

Anyways, the equation for the hyperfocal distance, which is
H = f^2/ac
with f the focal length, a the aperture number, and c the circle of confusion. The equation for the far field of sharpness is
F = s(H-f)/(H-s)
with s the focus distance. The near field of sharpness is
N = s(H-f)/(H+s-2f)
For a given a, plot N and F vs. s on a graph. More handy to refer to than using a Palm Pilot!

If my lens do not indicate the value for circle of confusion, what is the general value to use?

Hehe, OT
but if anyone wants to software for use on a Sharp Zaurus, here's the one i using...

Are there any java (j2me) version that can run on nokia 6610/6100?

sounds gd if there is.. cos i dun hav a palm, and i can't lug my desktop ard... even if i can also cannot find so many electric socket... (pull out the lamp post wire from under the ground... )
