Calculates the range of distance in a photo that appears acceptably sharp, based on focal length, aperture, subject distance, and sensor size.
Start with your values, or try a preset.
Enter Focal Length (mm), Aperture (f-number), Subject Distance (meters), and Sensor Width (mm) in the units shown.
Read Hyperfocal Distance (meters), Far Focus Distance (meters), Near Focus Distance (meters), and Depth of Field (meters) in the results panel. Results update as you change the inputs.
Choose a preset to load an example, then adjust the values for your situation.
See the inputs and their calculated results.
