ZOOM LENS AND IMAGE PICKUP APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240103258 titled 'ZOOM LENS AND IMAGE PICKUP APPARATUS

Simplified Explanation

The patent application describes a zoom lens with a unique configuration of fixed and moving lens units that change position during zooming to achieve desired optical effects.

• The zoom lens includes:

 * A first lens unit with positive refractive power that remains fixed during zooming.
 * Three or more moving lens units that can be adjusted during zooming.
 * A final lens unit with positive refractive power that also remains fixed during zooming.
 * At least one moving lens unit closest to the image plane or the final lens unit includes a first lens with positive refractive power.
 * The configuration of the lens units satisfies a predetermined condition.
