Technical Notes
Formula for determining the minimum subject
illumination for different F value
The amount of light passed through a lens is expressed by a value
called "aperture value" (F value or F number). When the aperture is
fully open (maximum aperture), the maximum amount of light is
passed through the lens. This is the lens' brightness and is
expressed by the "maximum aperture F value". The maximum
aperture F value is obtained by dividing the focal length with the lens
diameter (D). The capital letter "F" is used to distinguish it from "f",
which means the focal length.

Example:
For a lens of F1.2,
use the value of 1.0 lx
which is obtained by
actual measurement.

For the comparison of the minimum subject illumination:
Always confirm the F value and the IRE level used in the
measurement. If the F value and the IRE level do not
match, then convert the values in camera specifications
