Hyperfocal Distance Calculator
Find the hyperfocal distance for your lens and aperture — the focus point that keeps everything from half that distance to infinity acceptably sharp.
How it works
H = f² ÷ (N × c) + f · near limit when focused at H = H ÷ 2 · f = focal length, N = f-number, c = circle of confusion
The hyperfocal distance is the closest point you can focus on while still keeping the far horizon acceptably sharp — and it is the single most useful number in landscape photography. Focus exactly at the hyperfocal distance and your depth of field stretches from half that distance all the way to infinity, squeezing the maximum possible sharp zone out of a given aperture. It depends on focal length, aperture and the sensor’s circle of confusion (the largest blur spot that still reads as sharp, which shrinks on smaller sensors). Wider lenses and smaller apertures pull the hyperfocal distance closer, which is why landscape shooters favour wide-angle glass stopped down to f/8–f/16.
Worked example
A 35 mm lens at f/8 on a full-frame body (CoC 0.030 mm) has a hyperfocal distance of 35² ÷ (8 × 0.03) + 35 ≈ 5,139 mm, about 5.14 m. Focus there and everything from roughly 2.57 m to infinity is acceptably sharp.
Frequently asked questions
What is the hyperfocal distance?
It is the focus distance that maximises depth of field: focus there and the sharp zone runs from half that distance to infinity. It gives the deepest possible field for a given aperture, which is why it is the go-to focusing trick for landscapes.
How does it differ from depth of field?
Depth of field is the near-to-far sharp zone around any focus point; the hyperfocal distance is the specific focus point that pushes the far edge of that zone out to infinity. Focusing beyond the hyperfocal distance wastes depth behind infinity; focusing closer loses the horizon.
Why does sensor size change the result?
Smaller sensors use a smaller circle of confusion because their images are enlarged more to the same print size, which increases the hyperfocal distance for the same lens and aperture. That is one reason equivalent framing behaves differently across formats.
