ZOOM LENS, AND IMAGE PICKUP APPARATUS HAVING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 18508283 titled 'ZOOM LENS, AND IMAGE PICKUP APPARATUS HAVING THE SAME
Simplified Explanation
The abstract describes a zoom lens with multiple lens units that change position during zooming, with specific refractive powers and arrangements.
- The zoom lens comprises a plurality of lens units, including a first unit with negative refractive power, a second unit with positive refractive power, a third unit with negative refractive power, and a fourth unit with positive refractive power.
- The distance between adjacent lens units changes during zooming from wide-angle to telephoto.
- The first lens unit includes three or more lenses and remains fixed relative to the image plane during zooming.
- The design satisfies a predetermined inequality to optimize performance.

Original Abstract Submitted
A zoom lens comprising a plurality of lens units. The plurality of lens units consists of, in order from an object side to an image side, a first lens unit having negative refractive power, a second lens unit having positive refractive power, a third lens unit having negative refractive power, and a fourth lens unit having positive refractive power. A distance between adjacent lens units changes during zooming from a wide-angle end to a telephoto end. The first lens unit includes three or more lenses. The first lens unit is fixed relative to an image plane during zooming. A predetermined inequality is satisfied.
