Hyperfocal Distance Calculator.
Calculate the hyperfocal distance and the near limit at that focus.
H = f² / (N × c) + f. The near limit is H/2. Presets are conventional circles of confusion. Local arithmetic only. This is a quantity or geometry estimate, not a code check and not a substitute for a licensed professional.
- Hyperfocal distance
- 10.466667 m
- Near limit at that focus
- 5.233333 m
H = f² / (N × c) + f. Focusing at H keeps acceptable sharpness from about H/2 to infinity for the circle of confusion you selected.
How to use Hyperfocal Distance Calculator
Enter focal length, aperture and a circle of confusion. The near limit at the hyperfocal focus is about half that distance.
How it works
Calculate the hyperfocal distance and the near limit at that focus. H = f² / (N × c) + f. The near limit is H/2. Presets are conventional circles of confusion. Local arithmetic only. This is a quantity or geometry estimate, not a code check and not a substitute for a licensed professional.
Example
50 mm at f/8 with a 0.030 mm circle of confusion.
