To realize the illustrations of this technical appendix, rays tracing is computed by the trigonometrical method (Snell-Descates’ law - without any approximations), using the data taken from the quoted documents. Although limited to meridional plane calculations, this method allows excellent accuracy rays tracing. Therefore, it is a very efficient tool for the understanding of optical systems operation.

Focal Length and the Magnification.
Telephoto Zooms Lenses.
Fisheyes.
