Original Abstract Submitted
An optical imaging system includes a first lens, a second lens, a third lens, a fourth lens having negative refractive power, a fifth lens having positive refractive power, a sixth lens having a convex image-side surface, and a seventh lens, disposed sequentially from an object side. The optical imaging system satisfies −5.0<f2/f<−2.0, where f is a focal length of the optical imaging system and f2 is a focal length of the second lens. An F No. of the optical imaging system is less than 1.7.
