Patent ID: 10353193

Abstract:
An ultra-wide angle camera lens is provided. The lens includes, from an object side to an image side: a first lens with negative refractive power, an image-side face of the first lens being concave; a second lens with negative refractive power, an image-side face of the second lens being concave; a third lens with positive refractive power, an object-side face of the third lens being convex; a fourth lens with positive refractive power, an image-side face of the fourth lens being convex; and a fifth lens with negative refractive power, an image-side face of the fifth lens being concave. The lens satisfies: −0.05<f/f1<0; and 1.2<ImgH/f<2, in which, f represents an effective focus length of the ultra-wide angle camera lens, f1 represents an effective focus length of the first lens L1, and ImgH is half of a diagonal line of an effective pixel region on an imaging face.
