In this paper, we introduce the optical design concept applied to the latest 2/3-inch 4K zoom lens having a higher than 80x zoom range. The paper will further explain how Canon has realized 4K optical performance – while maintaining physical size and zoom ratio equivalent to the latest HDTV lenses – by referring to patent-pending technologies encompassing optical power layout, lens construction, and glass material combinations. |
