Abstract
An optical imaging system includes a first lens having a convex image-side surface, a second lens having a concave object-side surface, a third lens, a fourth lens, and a fifth lens disposed sequentially from an object side. The optical imaging system satisfies 4.8<f/IMG_HT<9.0, where f is a focal length of the optical imaging system, and IMG_HT is half a diagonal length of an imaging surface of an image sensor.
