Most distant point on the optical axis with an image of “acceptable sharpness”
Where CoC is the Circle of Confusion (the largest accepted Airy-disk) in Millimeter.
Alternatively, we can express the FarPoint using the magnification M :
A 5 Mega lens with f=7.2mm focal length and F-stop F2.4, focused to an object distance of 100mm then has a far point of
und einen Nahpunkt von
and thus
A 5 Mega lens with f=7.2mm focal length and F-stop F2.4, focussed to 100mm then results in
mm
und einen Nahpunkt von
thus we get

The DOF is then, thus focussing to the hyperfocal distance results in the largest possible DOF.
