Abstract

Designs of two-lens systems for use as 16-mm cinematograph projector objectives have been developed at a focal length of 50 mm and relative apertures of f/1.4 and f/1.2, respectively. The 50-mm f/1.4 system is comprised of five elements, and the 50-mm f/1.2 system is comprised of six elements. The proposed designs are not based on any known configuration, but their forms are arrived at from a hybrid approach combining the good points of some of the better known systems. The proposed systems are capable of giving extremely good performance, which has not been possible so far in the lenses of the same complexity in current use.
