An optical imaging system includes a first lens, a second lens, a third lens, a fourth lens, and a fifth lens, sequentially disposed from an object side, wherein the first to fifth lenses are spaced apart from each other by predetermined distances along an optical axis in a paraxial region, the first lens and the second lens each have a non-circular shape when viewed in an optical axis direction, and the optical imaging system satisfies 0.62398<ZS1/ZS2<1.36318, where ZS1 is a ratio of an area of an object-side surface of the first lens to a distance from the object-side surface of the first lens to an imaging plane of an image sensor, and ZS2 is a ratio of an area of an object-side surface of the second lens to a distance from the object-side surface of the second lens to the imaging plane of the image sensor.

Portable electronic device, optical imaging system, and lens assembly

A camera module is provided. The camera module includes a lens module including one or more lenses; an image sensor configured to convert light passing through the lens module into an electrical signal; and a filter configured to perform a polarization function, wherein the filter is configured to be movable in a space formed between the lens module and the image sensor.
