I just noticed the iphone screenshot. WTH? Focus point in the example is 5ft 26in? Isn't that the same as 7ft 2in? Or 86 inches? What kind of weird, illogical, un-intuitive interface is that?
LOL! I hadn't noticed that. Perhaps some people find it easier to think in terms of 36" rather than 3'. At least that's the only explination I can think of. Thanks for pointing that out!

I've got a Java app on my Nokia phone (6288, S40v3) that calculates DoF. Works for all cameras, if you know the 'crop factor'. I'll try to check where I got it from, if I forget or you are interested, feel free to remind me via PM.

About the "Depth of Field Calculator"; this is probably a dumb question but when using the calculator for a 15-55 kit lens, how do I figure out what number to use for the focal lenght?

15 and 55. Remember on APS-C The focal length is not changed there is only a cropping that happens in the image.

I appreciate your reply. Thank you.
I have a Pentax SMC-M MACRO 1:4 50mm lens and a 1:2.8 28mm lens I bought on e-Bay in the mail to me. So, there is no problem with determining the focal lenght for those lenses. I also have a Canon S3IS with a 6-72mm 1:2.7-3.5 lens. The camera is listed in the table in the "Depth of Field Calculator." Is 75 the number I should use for that lens? (I hope it's OK to ask a question about a Canon camera in this Pentax forum.)

Maybe one of these? Works with the S40 phones... (and possibly any java enabled phone as well) ...

If you have one of these you don't NEED a DOF calculator.

As matter of fact, it still works

Whats with all the mental graphs. Your distance scale on your lens tells you all that?
