What is hyperfocal distance?

The hyperfocal distance is the closest focus distance where everything from half that distance to infinity is acceptably sharp. It gives the maximum depth of field for a given aperture and focal length.

How do I use hyperfocal distance in the field?

Calculate the distance before you shoot, then manually focus to that distance using the distance scale on your lens or by estimating. Use live view magnification to verify focus on a near object.

Does hyperfocal focusing work with all lenses?

Yes, but it works best with wide to standard focal lengths (14-50mm). With telephoto lenses, the hyperfocal distance becomes very large, making it impractical for most scenes.

What aperture should I use for landscapes?

f/8 to f/13 is the sweet spot on full frame. This gives a good hyperfocal distance while avoiding diffraction softening that occurs at f/16 and smaller.

Hyperfocal Distance Calculator — Maximum Sharpness Range

Find the focus distance that maximises depth of field from the nearest sharp point to infinity.

Focal Length

Lens focal length in mm. Wide lenses (14–35mm) give short hyperfocal distances; telephotos push it far away. Use the actual marked focal length, not the equivalent.

Aperture (f-number)

The f-stop you will shoot at. Smaller f-numbers (wider apertures) push the hyperfocal distance further; f/8–f/13 is the landscape sweet spot before diffraction softens detail.

Sensor SizeSets the circle of confusion (CoC) — the largest blur spot that still looks sharp. Smaller sensors use a smaller CoC (full-frame CoC ÷ crop factor), which lengthens the hyperfocal distance. Pick your format or enter a custom CoC.

How We Calculate This

The hyperfocal distance formula is:

H = f² / (N × c) + f

Where f = focal length (mm), N = f-number, c = circle of confusion (mm). When you focus at H, everything from H/2 to infinity is acceptably sharp.

Example: 24mm at f/11, full frame (c=0.029mm): H = 576/(11×0.029) + 24 = 1829mm = 1.83m. Near sharp limit = 0.91m.
