What Is Hyperfocal Distance?

The hyperfocal distance is the focus point that maximizes depth of field: focus there and everything from half that distance to infinity is acceptably sharp. The formula: H = f² ÷ (N × c) + f, with focal length f, f-number N and the sensor's circle of confusion c. It is the landscape photographer's single most useful number.

Example: 24 mm at f/8 on full frame gives H ≈ 2.4 m — focus at 2.4 m and sharpness runs from 1.2 m to infinity. Wide lenses and small apertures push H closer, which is why 16-35 mm lenses barely need focusing at f/11.

Frequently Asked Questions

How do I actually set hyperfocal focus in the field?

Calculate H, then focus on an object at roughly that distance (pace it off or use your lens scale). Do not just focus at infinity — that wastes the near half of your depth of field.

What happens if I focus slightly closer than H?

The far limit drops below infinity quickly — distant mountains go soft. Erring slightly beyond H is safer than short of it.
