Hyperfocal distance

In landscapes you often want everything sharp, from the stones at your feet to the hills. The trick isn’t to focus at infinity, but at a precise distance: the hyperfocal distance.

1Simulator

Work out and test the hyperfocal distance

Choose the focal length and aperture, then decide where to focus. The scale under the photo is the one you used to find on manual lenses. The blur is exaggerated, as if you were looking at a large print: that way you can see it even on the screen of an iPhone or an Android smartphone.

How it works

1Simulator If you focus at infinity, half the depth of field ends up beyond infinity and is wasted. If you focus at the hyperfocal distance, the sharp zone runs from half that distance all the way to infinity.

1Simulator The formula is H = f² / (N × c) + f, where f is the focal length, N the aperture and c the circle of confusion: about 0.03 mm on full frame, 0.02 mm on APS-C.

In street photography the same idea is used with the focus fixed at 2–3 metres and the aperture stopped down. Ricoh GR cameras have a dedicated control for it, Snap Focus: on the GR IV you choose 0.3, 1, 1.5, 2, 2.5, 3.5 or 5 metres, or infinity. Fujifilm cameras show the depth-of-field scale when you focus manually; with Nikon, Canon and Sony you focus manually and check the distance on the indicator in the viewfinder, with lenses that report it.

Key points

  • Focusing at infinity wastes depth of field: half of the sharp zone is lost.
  • With the focus at the hyperfocal distance H, everything is sharp from H/2 to infinity.
  • Short focal length and narrow aperture = a close hyperfocal distance. With a 24 mm at f/11 on full frame it’s about 1.8 m.

Try it yourself

With a wide-angle lens at f/11, focus manually at about 2 metres and photograph a landscape with something in the foreground one metre away. Zoom into the photo: the foreground and the horizon should both be sharp.

Quick check

You focus at a hyperfocal distance of 3 m. What’s sharp, from where to where?
