</timeline>|width=520|caption=[[Depth of field|Depths of field]] of 3 ideal [[lens]]es of [[focal length]]s, {{math|''f''{{sub|1}}}}, {{math|''f''{{sub|2}}}} and {{math|''f''{{sub|3}}}}, and [[f-number]]s {{math|''N''{{sub|1}}}}, {{math|''N''{{sub|2}}}}, and {{math|''N''{{sub|3}}}} when focused at objects at different distances. {{math|''H''{{sub|1}}}}, {{math|''H''{{sub|2}}}}, and {{math|''H''{{sub|#}}}} denote their respective hyperfocal distances (using ''Definition 1'' in that article) with a [[circle of confusion]] of {{val|0.03|u=mm}} diameter. The darker bars show how that, for fixed subject distance, the depth of field is increased by using a shorter focal length or smaller aperture. The second topmost bar of each set illustrates the configuration for a [[fixed focus]] [[camera]] with the focus permanently set at the hyperfocal distance to maximise the depth of field. }}

As an example, for a {{val|50|u=mm}} lens at {{f/|8}} using a circle of confusion of {{val|0.03|u=mm}}, which is a value typically used in {{val|35|u=mm}} photography, the hyperfocal distance according to ''Definition 1'' is

<math display="block">H = \frac{(50)^2}{(8)(0.03)} + (50) = 10467 \mbox{ mm}</math>

If the lens is focused at a distance of {{val|10.5|u=m}}, then everything from half that distance ({{val|5.2|u=m}}) to infinity will be acceptably sharp in our photograph. With the formula for the ''Definition 2'', the result is {{val|10417|u=mm}}, a difference of 0.5%.
