Focus Rail: Depth of Field

Know what stays in focus before you take the shot. Enter your subject distance, choose a sensor, focal length and aperture, and see the near limit, far limit, total depth and hyperfocal distance. Compare apertures for the same scene on one distance scale, then apply the aperture you want. • Full Frame, APS-C, APS-C Canon, Micro Four Thirds and 1-inch sensors. • Metres and feet with localized number entry. • Focal-length slider and lens/aperture presets. • Use the hyperfocal distance with one tap. • Save up to 30 setups, restore them or share a calculation. • Seven release languages: English, French, German, Spanish, Italian, Japanese and Brazilian Portuguese. Calculations use a standard circle-of-confusion model. The app does not control your camera or measure a scene automatically. All features are included in the paid download. No account, ads, subscriptions or tracking.

Calculate near and far focus limits, compare apertures, and save or share shooting setups. Includes seven app languages and private on-device storage.
