Calculates Hyperfocal Distance, Near Focus Limit, Far Focus limit, and Depth of Field (DoF). DoF Calculator allows photographers to calculate the depth of field and hyperfocal distance for any given settings. It calculates the near limit, far limit, total depth of field and the hyperfocal distance. The app shows all those calculated values in a clear manner without unnecessary information. Just choose your camera, aperture, focal length and focus distance and it shows you the depth of field.
