Compact system cameras (CSCs) are commonly used nowadays and feature enhanced video functionsand thin yet light interchangeable lenses. They differ from digital single-lens reflex (DSLR) cameras intheir lack of mirror boxes. CSCs, however, have autofocus (AF) speeds lower than those of conventionalDSLRs, requiring weight reduction of their AF groups. To ensure the marketability of large telephoto zoomlenses with fixed f/2.8 regardless of field angle variation, in particular, light weight AF groups are essential.
In this paper, we introduce a paraxial optical design method and present a new, large, telephoto zoomlens with f/2.8 regardless of the field angle variation, plus a lightweight AF group consisting of only onelens. Using the basic paraxial optical design and optimization methods, we fabricated a new and lighterzoom lens system, including a single-lens, lightweight AF group with almost the same performance
