Abstract
The present disclosure discloses an optical imaging system including, sequentially from an object side to an image side along an optical axis, a first lens having refractive power; a second lens having refractive power; a third lens having positive refractive power; a fourth lens having refractive power; and a fifth lens having refractive power. Half of a diagonal length ImgH of an effective pixel area on an imaging plane of the optical imaging system and an entrance pupil diameter EPD of the optical imaging system satisfy: 0.5<ImgH/EPD≤1.0.
