When the lens is focused on the hyperfocal distance, the depth of field extends from half the hyperfocal distance to infinity.
Photography, Phil Davis, 1972.
The hyperfocal distance is the point of focus where everything from half that distance to infinity falls within the depth of field.
John Shaw’s Landscape Photography, John Shaw, 1994.
… the hyperfocal distance setting … is simply a fancy term that means the distance setting at any aperture that produces the greatest depth of field.
How to Use Your Camera, New York Institute of Photography, 2000.
