Editing Hyperfocal distance (section)

== Two methods ==
There are two common methods of defining and measuring ''hyperfocal distance'', leading to values that differ only slightly. The distinction between the two meanings is rarely made, since they have almost identical values. The value computed according to the first definition exceeds that from the second by just one [[focal length]].

; Definition 1
: The hyperfocal distance is the closest distance at which a [[lens (optics)|lens]] can be focused while keeping [[infinity focus|objects at infinity]] acceptably sharp. When the lens is focused at this distance, all objects at distances from half of the hyperfocal distance out to infinity will be acceptably sharp.
; Definition 2
: The hyperfocal distance is the distance beyond which all objects are acceptably sharp, for a lens focused at infinity.
