Hyperfocal Focus Range

How to use this tool

1. Calculate hyperfocal distance and the near sharp limit when focused at that distance.
2. Set focal length, f-number, circle of confusion in the indicated units.
3. Calculate and compare hyperfocal distance, near limit at hyperfocal.

Try this example

{
  "f": 50,
  "n": 8,
  "c": 0.025
}

Accuracy and scope

Thin-lens approximation and a user-chosen acceptable circle of confusion; diffraction and visual viewing conditions are not assessed.
