Structure and image forming properties of asymmetrical wide angle lenses for 35-mm photography.
Image forming properties for four lens pairs of asymmetrical wide angle lenses are described with reference to Seidel Pegel diagrams. The comparative system analysis in the Seidel range is augmented by graphic representations of trigonometrically determined selected image aberrations, in order to demonstrate a correspondence between analytical aberration theory and actual aberrations. References to older systems of interesting lens types show the different principles used for the older designs in comparison with those for the newer integrated systems.
