1. An optical imaging system comprising:
a first lens comprising a positive refractive power, a convex object-side surface, and a concave image-side surface;
a second lens comprising a refractive power, a convex object-side surface, and a concave image-side surface;
a third lens comprising a refractive power, a convex object-side surface, and a concave image-side surface;
a fourth lens comprising a refractive power and a convex object-side surface;
a fifth lens comprising a negative refractive power and a convex object-side surface;
a sixth lens comprising a positive refractive power, a convex object-side surface, and a concave image-side surface; and
a seventh lens comprising a negative refractive power,
wherein the first lens, the second lens, the third lens, the fourth lens, the fifth lens, the sixth lens, and the seventh lens are disposed in order along an optical axis of the optical imaging system from an object side of the optical imaging system toward an image side of the optical imaging system.
