Classification: CPC G | IPC G

Claim 0:
1. An optical imaging system comprising:
a first lens comprising negative refractive power;
a second lens comprising a convex object-side surface;
a third lens comprising positive refractive power and a convex image-side surface;
a fourth lens comprising a refractive power;
a fifth lens comprising a convex image-side surface;
a sixth lens comprising a convex object-side surface; and
a seventh lens comprising a convex object-side surface,
wherein the first to seventh lenses are sequentially disposed from an object side toward an image plane, and
wherein TTL/2Y<1.3 is satisfied, where TTL is a distance from an object-side surface of the first lens to the imaging plane, and 2Y is a diagonal length of the imaging plane.
