1. An optical imaging system comprising:
a first lens having a positive refractive power, an object-side surface that is convex in a paraxial region thereof, and an image-side surface that is concave in a paraxial region thereof;
a second lens having a negative refractive power, an object-side surface that is convex in a paraxial region thereof, and an image-side surface that is concave in a paraxial region thereof;
a third lens having a positive refractive power;
a fourth lens having a negative refractive power, an object-side surface that is convex in a paraxial region thereof, and an image-side surface that is concave in a paraxial region thereof;
a fifth lens having a positive refractive power and an object-side surface that is concave in a paraxial region thereof;
a sixth lens having a refractive power; and
a seventh lens having a refractive power,
wherein the first to seventh lenses are sequentially disposed in ascending numerical order along an optical axis from an object side of the optical imaging system toward an image side of the optical imaging system.
