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 from an object side to an imaging plane. An angle of view of the optical system is 82 degrees or more. A constant indicating brightness of the optical system, F-number, is less than 1.8.
