Hyperfocal + Depth of Field Calculator

Estimate hyperfocal distance and near/far depth of field limits with documented assumptions. Choose from sensor presets or enter a custom circle of confusion value.

Assumptions

Hyperfocal distance uses H = (f² / (N · CoC)) + f. Distances are rounded to two decimals. Far limit is infinity when focus distance exceeds hyperfocal distance.

Worked Example

Scenario: Landscape with 24mm lens on full frame camera

Settings: f/8 aperture, focus at 3 meters

Hyperfocal distance: ~1.8m at f/8

Depth of field: Everything from ~1.2m to infinity appears sharp

Tip: Focus at hyperfocal distance for maximum sharpness from half that distance to infinity

FAQ

What is CoC (Circle of Confusion)?

The maximum blur diameter (in mm) that still appears sharp to the human eye. Smaller sensors need smaller CoC values.

What is hyperfocal distance?

The closest focus distance where the far limit of depth of field reaches infinity. Focus here for maximum sharpness from foreground to background.

Why does far limit show "infinity"?

When you focus at or beyond hyperfocal distance, everything from the near limit to infinity appears acceptably sharp.

Which sensor preset should I use?

Choose based on your camera: full frame (35mm), APS-C (crop sensor), Micro 4/3, or medium format. Check your camera manual for crop factor.

How accurate are these calculations?

Very accurate for the given CoC value, but real-world sharpness depends on lens quality, diffraction, and viewing conditions.
