ZOOM LENS AND IMAGE PICKUP APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240310611 titled 'ZOOM LENS AND IMAGE PICKUP APPARATUS
The abstract of the patent application describes a zoom lens with multiple lens units arranged from the object side to the image side. It includes a fixed first lens unit with positive refractive power, movable lens units with negative refractive powers for zooming, and a final fixed lens unit with positive refractive power closest to the image plane. The distance between adjacent lens units changes during zooming, and part of the first lens unit moves for focusing. The first lens unit consists of one negative lens and at least five positive lenses arranged in order from the object side to the image side.
- First lens unit with positive refractive power fixed for zooming
