Aspects of the design of complex photographic lenses for low cost, high production are considered. Extensive use is made of through-focus MTF for the assessment of image quality and for the establishment of tolerances and this concept is described in detail. The problem of desensitizing and tolerancing lenses is discussed and illustrated in terms of the design of a high quality, ultra wide-angle lens covering a field of 102° at f/3.5. The evolution of this design is shown and some interesting problems involved in the aberration correction are described. Brief mention is made of some manufacturing considerations and the extent to which these affect the optical design.
