What is hyperfocal distance technology?

When the lens is focused at infinity, the nearest limit of the depth of field near the camera is called hyperfocal distance. When the lens is focused on the hyperfocal distance with a certain aperture, the depth of field ranges from 1/2 to infinity. Hyperfocal distance is the fastest way to get the maximum depth of field or control the clear range of an image. For a lens with a Jing Shenbiao scale, it is very simple to determine the hyperfocal distance: just focus on infinity, and then you can see the depth of field range from infinity to a point close to the camera indicated by the used aperture from the Jing Shenbiao of the lens. The distance from the camera to the depth of field is hyperfocal distance.
