Abstract: A wide angle optical lens assembly includes a first lens group and a second lens group arranged in order from an object side to an image plane along an optical axis, satisfying the following condition: 2.0?|F1/EFL|?3.65; 2.6?|F2/EFL|?3.45; wherein, EFL is effective focal length of the wide angle optical lens assembly; F1 is effective focal length of the first lens group; F2 is effective focal length of the second lens group. The first lens group includes a first lens having negative refractive power, a second lens having negative refractive power, and a third lens having positive refractive power arranged in order from the object side. The second lens is a meniscus lens, having a convex image-side surface. The second lens group includes a fourth lens having positive refractive power, a fifth lens having negative refractive power, and a sixth lens having positive refractive power arranged in order from the object side.

Abstract: A wide angle lens assembly having low distortion including, in order from an object side to an image plane, a first lens, which is of a meniscus shape having an object side surface being convex and an image side surface being concave, having negative refractive power; a second lens having positive refractive power; a third lens having positive refractive power, and a fourth lens having negative refractive power; the wide angle lens assembly satisfies the following condition: ?0.6<f34/f12<?0.4; wherein f12 is a composite focal length of the first lens and the second lens, and f34 is a composite focal length of the third lens and the fourth lens.
