HHyperfocal Distance

The closest point you can focus a lens and still have the depth-of-field including infinity when the lens is focused on infniity. On a NIKKOR lens that does not have a depth-of-field scale, you can calculate the hyperfocal distance by using the formula: H = f 2 / ( F x CoC ) where "H" is the hyperfocal distance in mm, "f" is the focal length, "F" is the aperture and "CoC" is a Circle of Confusion value (0.033 for 35mm film or an FX format camera or 0.020 for a DX format body). The maximum permissible circle of confusion will vary depending on the image reproduction size, image capture format and other variables.
