DoF Calc is a photography application available for Android devices that allows users to calculate the "Near Focus Limit", "Far Focus Limit", "Hyperfocal Distance", and "Depth of Field" based on selected camera, aperture, focal length, and focus distance. The app features wheels for selecting aperture, focal length, focus distance, and unit of focus distance, making testing of different settings fast and simple.

Users can individually select the unit of the calculated results and focus distance to be meter, centimeter, feet, or inch, and all last used settings are saved. The app is free to use and can be downloaded from the Google Play Store.

If users are missing a camera/sensor or have any other request, they can contact the developer, JDS, for assistance. DoF Calc is a useful tool for photographers who want to calculate the depth of field quickly and accurately.
