Summary:An optical imaging system is provided. The optical imaging system includes a first lens, a second lens, a third lens, a fourth lens, a fifth lens, and a sixth lens sequentially disposed from an object side to an imaging side. In the optical imaging system, the first lens has positive refractive power and has a concave object-side surface, the fourth lens has negative refractive power, and the fifth lens has a convex image-side surface. Additionally, the optical imaging system satisfies the following conditional expressions: f number<1.90 and 1.90<TTL/f<2.2. In the conditional expressions, TTL is a distance from an object-side surface of the first lens to an image plane, and f is a focal length of the optical imaging system.
