1. An optical imaging system, comprising:
a total of six lenses with refractive power, the six lenses comprising:
a first lens comprising a refractive power;
a second lens comprising a convex object-side surface;
a third lens comprising a convex object-side surface;
a fourth lens comprising negative refractive power;
a fifth lens comprising a refractive power; and
a sixth lens comprising a refractive power, and a convex object-side surface in a paraxial region,
wherein the first to sixth lenses are sequentially disposed from an object side toward an imaging plane,
wherein a thickness of the fifth lens along an optical axis is greater than a thickness of four lenses along an optical axis, and
wherein 80°<FOV, where FOV is a field of view of the optical imaging system.
