Wide angle lens assembly having low distortion

A wide angle lens assembly having low distortion, comprising, 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;
• wherein the wide angle lens assembly further comprises an image sensor disposed on the image plane, and satisfies the following condition:
• 0.2<ImH/(f*TTL)<0.6;
• wherein, ImH is half of a diagonal length of an effective sensing area of the image sensor S;
• f is a composite focal length of the first lens to the fourth lens;
• TTL is a distance on an optical axis of the wide angle lens assembly between the object side surface of the first lens to the image plane.
