Not sure if this site has been posted before or if I should have posted this in another thread... so mods please move if so.

I found this site very helpful.

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?

Pentaxoid · 12-07-2009, 10:09 AM

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.)

There is a downloadable DOF calculator for Win:

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

Thanks a lot for DOF online calculator, Nulla.

Basie · 10-08-2012, 01:03 PM

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

As matter of fact, it still works

tromboads · 10-08-2012, 09:40 PM

Que?

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

Thanks for this tip

Well, it's an old thread but anyway..
I've found a very cool DoF simulator, which not only calculates the DoF, but also gives visual representation - it shows how a picture would look based on different settings (not only focal length, aperture and distance to the subject, but also distance to the background, various types of apertures (7-blades, 9-blades, etc.).
It also have a dedicate offline apps for Win, OSX, Linux and Android.

You can find it here - DOF simulator - Camera depth of field calculator with visual background blur and bokeh simulation.

Thanks for bringing it up again. I'll change the title and make it a sticky.

I downloaded this app on my Android version 6.0
