It is usually set to the hyperfocal distance, so that the depth of field ranges all the way down from half that distance to infinity, which is acceptable...

u′ are the image and object distances parallel to the line of sight, uh is the hyperfocal distance, and J is the distance from the center of the lens...

diameter limit, either of these can be solved for subject distance to get the hyperfocal distance, with approximately equivalent results. Before it was applied...
