1. An optical imaging system comprising:
a first lens having positive refractive power;
a second lens having refractive power;
a third lens having refractive power;
a fourth lens having refractive power; and
a fifth lens having refractive power, 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,
wherein a length of the first lens in a first axial direction perpendicular to the optical axis is longer than a length of the first lens in a second axial direction perpendicular to both the optical axis and the first axial direction, and
wherein the optical imaging system satisfies 1.351 mm<ZS1<1.811 mm, where ZS1 is a ratio of an area of an object-side surface of the first lens to a distance on the optical axis from the object-side surface of the first lens to an imaging plane of an image sensor.
