What is 8x Four-Group Zoom Lens Design about?

This document presents the design and analysis of an 8x four-group zoom lens system utilizing focus tunable lenses (FTLs) for a compact camera, eliminating the need for moving groups. The system achieves a zoom ratio of 8x with focal lengths ranging from 4 to 31 mm and apertures between F/3.5 and F/4.5. The study emphasizes the importance of analyzing principal point shifts during zooming to create a physically meaningful and compact optical design.
