Hyperfocal Distance
Find the hyperfocal distance and the near limit of sharp focus at that setting.
About Hyperfocal Distance
Focusing at the hyperfocal distance puts everything from half that distance out to infinity acceptably sharp. Landscape photographers use hyperfocal focusing to maximize sharpness with a closed aperture and no focus aid.
Formula
Hyperfocal Distance
Hyperfocal H = f^2 / (N x coc); near limit = H / 2
- coc
- Circle of confusion, reduced as crop factor rises
Worked example
With the default values below, Hyperfocal Distance returns Hyperfocal Distance of 15.68. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits
- The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
- In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
- Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
Frequently Asked Questions
How is Hyperfocal Distance calculated?
Hyperfocal H = f^2 / (N x coc); near limit = H / 2 Focusing at the hyperfocal distance puts everything from half that distance out to infinity acceptably sharp.
Why does Hyperfocal Distance matter?
Landscape photographers use hyperfocal focusing to maximize sharpness with a closed aperture and no focus aid.
What values do I need to enter?
This calculator takes 3 inputs: Focal length, Aperture (f-number), Crop factor. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
