1. An optical imaging system, comprising:
a first lens having positive refractive power;
a second lens having negative refractive power, and a convex object-side surface;
a third lens having positive refractive power, and a concave image-side surface;
a fourth lens having negative refractive power, and a concave image-side surface;
a fifth lens having negative refractive power, and a concave image-side surface; and
a sixth lens having positive refractive power, and a convex object-side surface in a paraxial region,
wherein the optical imaging system has a total of six lenses with refractive power,
wherein the first to sixth lenses are sequentially disposed from an object side to an image side, and
wherein a thickness of the third lens is greater than a thickness of the fourth lens.
