Hyperfocal Distance Calculator
Hyperfocal Distance
Calculate the hyperfocal distance for maximum sharpness
Aperture Comparison
Compare hyperfocal distances at different apertures
Formula
H = f²/(N×c) + f | Near limit = H/2 | Far limit = Infinity | where f=focal length, N=f-number, c=circle of confusion
Frequently Asked Questions
What is hyperfocal distance?
Hyperfocal distance is the closest focus distance at which everything from half that distance to infinity appears acceptably sharp. It maximizes the depth of field for a given focal length and aperture.
When should I use hyperfocal distance?
Use hyperfocal focusing for landscape photography, street photography, and any scene where you want maximum sharpness from foreground to background. It's especially useful with wide-angle lenses.
Why not just focus at infinity?
Focusing at infinity wastes depth of field. Half the DOF extends behind infinity (unusable). By focusing at the hyperfocal distance, you bring the near focus limit much closer while keeping infinity sharp.
