Abstract

An optical imaging system and portable electronic equipment are disclosed. The optical imaging system includes a first lens having positive refractive power, a second lens, a third lens, a fourth lens, and a fifth lens, arranged in order from an object side to an image side. The first lens is shaped such that a length of a first axis, which intersects an optical axis, is greater than a length of asecond axis, which intersects the optical axis and is perpendicular to the first axis and wherein the following conditional expressions are satisfied: 4.5<TTL / IMG HT<6.5; 0.87<TTL / f<1.31; and 0.65<L1S1es / L1S1el<0.9, where TTL is a distance on the optical axis from an object-side surface of the first lens to an imaging surface of an image sensor, IMG HT is half a diagonal length of the imaging surface of the image sensor, f is a total focal length of the optical imaging system, L1S1el is a maximum effective radius of the object-side surface of the first lens, and L1S1es is a minimum effectiveradius of the object-side surface of the first lens.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of priority to Korean Patent Application No. 10-2019-0107775 filed with the Korean Intellectual Property Office on August 30, 2019, the entire disclosure of which is incorporated by reference into this application for all purposes . technical field [0003] The following description refers to optical imaging systems. Background technique [0004] Cameras are already used in portable electronic devices such as smartphones. Due to the demand for miniaturization of such portable electronic devices, cameras mounted on portable electronic devices have been required to be miniaturized. [0005] In addition, telephoto cameras have been employed in portable electronic devices to obtain a zoom effect for capturing objects with a relatively narrow field of view. [0006] However, when a plurality of lenses are arranged in the portable electronic device in the thickness direction, the thickn...
