Lens Assembly, Camera Module, and Electronic Device

原文（中国語）

A lens assembly may include a first lens element unit and a second lens element unit that are arranged along an optical axis from an object side to an image side, and the second lens element unit may move along the optical axis toward the image side to switch the lens assembly between an infinity state and a macro state. In addition, focal powers of the first lens element unit and the second lens element unit and a focal power of a first lens element closest to the object side are properly allocated.
