Hyperfocal Distance

Hyperfocal distance is the nearest focused distance such that the point at infinity still appears sharp.

Hyperfocal distance equals the focal length squared divided by the circle of confusion and the f-number.

Formula

QuantityVariable["h", "Distance"] == QuantityVariable["f", "Length"]^2/(QuantityVariable["c", "Length"]*QuantityVariable["N", "Unitless"])

symbol description physical quantity
h hyperfocal distance "Distance"
c circle of confusion "Length"
f focal length "Length"
N f­number "Unitless"
