Hyperfocal Distance Formula
The following formula is used to calculate the Hyperfocal Distance.
HD = FL^2 / (CoC * F-s)
- Where HD is the Hyperfocal Distance (mm)
- FL is the focal length (mm)
- Coc is the circle of confusion (mm)
- F-s is the f-stop
How to Calculate Hyperfocal Distance?
The following example problems outline how to calculate Hyperfocal Distance.
Example Problem #1
- First, determine the focal length (mm).
- The focal length (mm) is calculated to be : 5.
- Next, determine the circle of confusion (mm).
- The circle of confusion (mm) is measured to be: 2.
- Next, determine the f-stop.
- The f-stop is found to be: 5.
- Finally, calculate the Hyperfocal Distance using the formula above:
HD = FL^2 / (CoC * F-s)
The values given above are inserted into the equation below and the solution is calculated:
HD = 5^2 / (2 * 5) = 2.5 (mm)
Example Problem #2
The variables needed for this problem are provided below:
focal length (mm) = 6
circle of confusion (mm) = 7
f-stop = 8
This example problem is a test of your knowledge on the subject. Use the calculator above to check your answer.
HD = FL^2 / (CoC * F-s) = (mm)
