Note
•Allow a margin of error in the value in the diagrams above.
•When the distance from the lens center to the bottom of the image [H] is a negative number, this indicates that the bottom of the image is below the lens center.
•See page 21 about projection distance [L] and distance from the lens center to the bottom of the image [H].
