1. An optical imaging system comprising:
a first lens having a positive refractive power, a convex object-side surface in a paraxial region thereof, and a convex image-side surface in a paraxial region thereof;
a second lens having a negative refractive power;
a third lens having a negative refractive power;
a fourth lens having a refractive power, a convex object-side surface in a paraxial region thereof, and a concave image-side surface in a paraxial region thereof;
a fifth lens having a negative refractive power; and
a sixth lens having a positive refractive power and a convex image-side surface in a paraxial region,
wherein the first to sixth lenses are sequentially disposed on an optical axis from an object side toward an image side,
wherein 2.2<D23/D34<5.4 is satisfied, where D23 is a distance on the optical axis between the second lens and the third lens, and D34 is a distance on the optical axis between the third lens and the fourth lens, and
wherein 10<D23/D12<22 is satisfied, where D12 is a distance on the optical axis between the first lens and the second lens.
