1. An optical imaging system comprising:
a first lens comprising a refractive power;
a second lens comprising a refractive power;
a third lens comprising a convex object-side surface;
a fourth lens comprising negative refractive power;
a fifth lens comprising a refractive power;
a sixth lens comprising a refractive power; and
a seventh lens comprising a refractive power,
wherein the first to seventh lens are sequentially disposed from an object side toward an imaging plane,
wherein a radius of curvature of an object-side surface of the second lens is greater than a radius of curvature of an image-side surface of the sixth lens, and
wherein 0.5<L12345TRavg/L7TR<0.9, where L12345TRavg is an average value of overall outer diameters of the first to fifth lenses, L7TR is an overall outer diameter of the seventh lens, and L12345TRavg and L7TR are expressed in a same unit of measurement.
