What hyperfocal distance means

The hyperfocal distance is the closest focus distance that still keeps infinity acceptably sharp. Focus there, and depth of field stretches from half that distance all the way to infinity, which is the maximum sharp zone any aperture can give.

The formula

Hyperfocal distance equals focal length squared divided by f-number times circle of confusion, plus the focal length. Wider lenses and smaller apertures pull it closer: a 24mm lens at f/8 on APS-C has a hyperfocal distance of about 3.8 meters.

Hyperfocal Distance FAQs

How do I use hyperfocal distance in the field?
Focus the lens at the calculated distance, using a distance scale or live view magnification. Everything from half that distance to infinity will be sharp.
Why does my lens have no distance scale?
Many modern lenses omit scales. Estimate the distance, focus on an object roughly that far away, or use your camera's distance readout in live view.
Is hyperfocal focusing always the sharpest choice?
Not always. It maximizes the sharp zone but infinity itself is only just acceptably sharp. For critical distant detail, focusing slightly beyond hyperfocal can help.
Does sensor size change hyperfocal distance?
Yes, through the circle of confusion. Smaller sensors use a smaller CoC, which lengthens the hyperfocal distance for the same lens and aperture.
What aperture is best for hyperfocal landscapes?
Usually f/8 to f/11, the lens sweet spot. Stopping down further lengthens diffraction softening, which can undo the depth of field gains.
