Claim 0:
1. An optical lens system of an electronic device, the optical lens system comprising:
a lens assembly;
an iris; and
an image sensor configured to form an image of an object corresponding to the lens assembly,
wherein the lens assembly includes:
a first lens having positive refractive power; and
a second lens having negative refractive power, and
wherein the iris, the first lens, and the second lens are sequentially arranged from an object-side to an image sensor-side along an optical axis,
wherein the electronic device further includes a housing surrounding at least a first portion of the lens assembly,
wherein the iris is disposed in a camera hole of the electronic device formed in an active area of a display panel,
wherein the iris is at least partially disposed in a plane of the display panel, and
the optical lens system of the electronic device satisfies Equations 1 and 2 below:, 1.1

wherein, STL is a distance from the iris to an image plane of the image sensor on the optical axis,
TL is a distance from an object-side apex of a lens closest to the object-side among a plurality of lenses included in the lens assembly to the image plane on the optical axis,
EPD is a diameter of an entrance pupil of the optical lens system, and S1 is a distance from the iris to the lens closest to the object-side among the plurality of lenses included in the lens assembly,
wherein the optical lens system further includes an extension extending from the housing of the lens assembly or from a fixed structure disposed in the electronic device, the extension at least partially enclosing a second portion of the lens assembly that extends beyond an interior of the housing, and an end thereof that is disposed at least partially within the camera hole, and
wherein the iris is disposed at the end of the extension.
