1. An optical imaging system comprising:
a first lens having positive refractive power;
a second lens having negative 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 the optical imaging system satisfies 1.607 mm<ZS1<2.014 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, and
wherein the optical imaging system satisfies f/IMG HT>4.9, where f is a total focal length of the optical imaging system, and IMG HT is one-half of a diagonal length of the imaging plane of the image sensor.
