The first lens is a glass or plastic lens having negative power and an incident surface convex towards an object. The second lens is a plastic lens having negative power, configured to be concave towards the image sensor, having at least one aspherical surface. The third lens is a plastic lens having positive power, both convex surfaces, and at least one aspherical surface. The fourth lens is a plastic lens having positive power, both convex surfaces, at least one aspherical surface, and a horizontal angle of view of 138° or greater and less than 147°. Accordingly, the present invention is able to precisely capture an image due to a wide angle of view and small distortion. COPYRIGHT KIPO 2017 ...
