hyperfocal distance

Noun

Meaning

the distance in front of a lens that is focused at infinity beyond which all objects are well defined and clear

Hypernyms

Examples

For example, on the Minox LX focusing dial there is a red dot between 2 m and infinity; when the lens is set at the red dot, that is, focused at the hyperfocal distance, the depth of field stretches from 2 m to infinity. Source: Internet

Hyperfocusing Zeiss Ikon Contessa with red marks for hyperfocal distance 20 ft at f /8 Some cameras have their hyperfocal distance marked on the focus dial. Source: Internet

Focusing on the hyperfocal distance is a special case of zone focusing in which the far limit of DOF is at infinity. Source: Internet

For example, with the 35 mm lens shown above set to f /11, aligning the infinity mark with the '11' to the left of the index mark on the DOF scale would set the focus to the hyperfocal distance. Source: Internet

If the lens includes a DOF scale, the hyperfocal distance can be set by aligning the infinity mark on the distance scale with the mark on the DOF scale corresponding to the f -number to which the lens is set. Source: Internet

It is important to note that this is true only when the subject distance is small in comparison with the hyperfocal distance; however, this is often the case in many photography scenarios. Source: Internet
