Because wide-angle lens has a wide angle of view, we face severe situation to improve peripheral performance.
Especially many recent wide-angle lens are necessary to have a back focus longer, whereby the asymmetry becomes stronger, it becomes difficult to correct distortion and lateral chromatic aberration.
In this speech, I will explain a Design Considerations on its features and aberration correction with each major lens type of symmetric and asymmetric.
