Zoom lens unit and camera

This is a camera zoom lens made of four groups of lenses. To zoom in or out, the second lens group moves while the first and fourth groups stay still. The invention specifically details the precise optical characteristics of one or two positive lenses in the fourth group to ensure good image quality.

Why it matters: The precise optical properties and tight manufacturing tolerances for the specified lens elements remain a significant cost and production challenge, despite general advancements in optical manufacturing since 2014.
