## What is Focus Rail?

Focus Rail: Depth of Field shows what stays acceptably sharp before you take the photograph.

Choose a sensor format, focal length, aperture, and subject distance. See the near limit, far limit, total depth of field, and hyperfocal distance, with a visual focus rail and meters or feet.

Save useful camera setups and restore them later. All calculations stay on this device, with no account, advertising, analytics, tracking, or server.

The app interface supports English, French, German, Spanish, Italian, Japanese, and Brazilian Portuguese.
