Abstract

The optical design of a high performance short focal length lens system and several derivatives thereof which cover the Super 16 mm film format is described. Particular areas of discussion include the use of internal close focusing optics to eliminate the need for precision focusing mechanics and the use of multiple aspheric surfaces, as well as, internal filtration to reduce system size, weight and cost. Other areas, concerning optical `breathing', distortion and material choice, especially very high index glasses, are also addressed.
