摘要： An optical imaging system includes lenses sequentially disposed from an object side of the optical imaging system toward an imaging plane of the optical imaging system, and a stop disposed between a third lens of the lenses and a fourth lens of the lenses. An object-side surface of the third lens is concave, and a ratio TL/f of a distance TL from an object-side surface of a first lens of the lenses to the imaging plane with respect to an overall focal length f of the optical imaging system is greater than 0.7 and less than 1.0.
