1. An optical imaging system comprising:
a first lens having negative refractive power, a concave object-side surface;
a second lens having positive refractive power, a convex object-side surface and a concave image-side surface;
a third lens having positive refractive power;
a fourth lens having negative refractive power;
a fifth lens having positive refractive power, a convex object-side surface and a convex image-side surface; and
a sixth lens having refractive power,
wherein the first to sixth lenses are sequentially disposed from an object side,
wherein an angle of view of the optical imaging system is 100° or more, and
wherein TTL1/F1>2.0 is satisfied, where TTL1 is a distance from the object side surface of the first lens to an imaging surface, and F1 is a total focal length of the optical imaging system.
