Abstract

The present application provides an optical lens system, an imaging device and an electronic device. The optical lens system provided by the present application includes sequentially from the object side to the image side: a first lens with negative refractive power; a second lens with positive refractive power; a third lens with positive refractive power; and a fourth lens with negative refractive power lens; a fifth lens with positive refractive power; and a sixth lens with negative refractive power; wherein, the optical lens system satisfies the following conditional formula: |tan(HFOV)| / TTL>0.50; -2.0<f1 / f <‑1; and 1.0<f2 / f<2.0; wherein, HFOV is half of the horizontal field of view of the optical lens system, TTL is the length from the object side of the first lens to the imaging plane on the optical axis, f is the focal length of the optical lens system, f1 is the effective focal length of the first lens, and f2 is the effective focal length of the second lens. The overall system length of the optical lens system of the present application is short, which can well meet the requirements of the miniaturization of the camera.
