Abstract
An optical imaging system includes a first lens, a second lens, a third lens, a fourth lens, a fifth lens, and a sixth lens sequentially arranged in numerical order from an object side of the optical imaging system toward an imaging plane of the optical imaging system and each having a refractive power, wherein an entire field of view of the optical imaging system is 50° or greater, and TTL/f<1.0, where TTL is a distance from an object-side surface of the first lens to the imaging plane, and f is an overall focal length of the optical imaging system.
