This KODAK application is now available as a free download from the iTunes App Store.

The new app helps filmmakers determine the correct settings for achieving desired focus, and easily connects them with Kodak around the world. There are fields for entering known data – such as film format, F-stop, focal length and subject distance – and then the app computes the near limit, far limit, hyperfocal distance and circle of confusion.

Results can be in feet or meters, and calculations can be made for any combination of remaining variables.
