Depth of Field Calculator for Windows Mobile 6

A friend of mine and I had the same little need lately. We would like a portable and easy Depth of Field Calculator for our camera. We both have a PocketPC with Windows Mobile 6, and there are several formulas for depth of field available on the net. So, here you are. This is a beta version of my little Depth of Field Calculator. Please tell me what you think.

Update 20080226 - Updated with Sony Alpha Digital SLR's as well

Note: This version only works with a full Pocket PC (Not Smartphone!)

Easier to find URL: >>Download Depth of Field Calculator

Update 2008-07-13: New Depth of Field Calculator Site

Hi Leirdal

Nice little application. Is it possible to make the crop-factor a variable or let the user add additional camera types?

If you are willing to share the source code I could also make a try.

Tanks in advance
and looking forward to your next release

Hello Patrik

To add additinal camera types:
It's easy to add cameras in the source-code. I haven't included functionality to let the users to that themselves, but of course that would be something for a later release. The hard part is for the users to find the correct value needed to do the calulations for that specific camera.

When you would like the crop-factor to be a variable I am not sure what you actually need. The main problem is probably the available display area. Can you give some description of what you are thinking of?

Sure I can publish the source-code. It will have to wait until the weekend though. I am not sitting at the computer with the source-code right now.

Thanks for your comments. They are appreciated.

Regards

Jon Leirdal

Hi Jon

And thanks for the quick reply. With the crop-factor beeing variable I am meaning the focal length multiplier depending on the sensor.

In the camera presets hard-coded in the app I guess you have defined them from specification to 1.5x, 1.6x or whatever.

However for me (owning a Sony Alpha 700) this app is of no use depending on my different crop-factor.

Therefor I am suggesting the possibility to either add new Cameras or changing the crop-factor.

Appoligies for my english I am from Sweden

Looking forward to the source code! I am a developer myself though I have never developed for WM.

Regards
Patrik

When I choose Canon 40d, 50mm, 1:1.8 and 1,50m distance I get different result (11cm) than choosing 150cm (5,89cm)?
Is that a bug?

Depends how you look on it. You can only input values available on the scale right now. So 1,5 metres is rounded up to two. I'll have a look at ways to improve that. Great find. Thanks...

Great little tool. I really like it. This limitation is easy to handle...

#2.1.1 Michael on 2008-06-16 17:07 (Reply)

Great little app! Just what I was looking for. I almost started to develop something of my own but this app seems to fit the need perfectly. Thanks!

It doesn't seem to work on my Motorola Q9h when installed to the device.

#4 TJ on 2008-06-02 04:11 (Reply)

Is that a smartphone or a pocket pc?

#4.1 Jon Leirdal on 2008-06-02 15:13 (Reply)

What a great tool! It's just wonderful - portable, easy to use, and very needed since so many lenses no longer provide DoF scales. Thanks so much for creating this needed program and making it available.

Agree! perfect application. I have also found an app for iPhone/iPod with some additional good to have tabs.

Hi there, I'm a Nikon user. Will it include Nikon models in the future?

#6 Zheng on 2008-09-24 10:40 (Reply)

I am working on a new version that includes the option to edit the camera list yourself. Within the application.
