The invention discloses a novel ultra wide angle lens. The novel ultra wide angle lens comprises a lens shell. Pieces of optical glass sequentially arranged from the object space to the image space inside the lens shell include a first lens, a second lens, a third lens, a fourth lens, a diaphragm component, a fifth lens, a sixth lens, a seventh lens and an eighth lens, wherein the first lens is a strawhat-type lens with the negative focal power, the second lens is a biconcave lens or a plane concave lens with the negative focal power, the third lens is a falcate lens or a biconvex lens with the positive focal power, the fourth lens is a falcate lens or a biconvex lens with the positive focal power, the fifth lens is a falcate lens or a biconvex lens with the positive focal power, the sixth lens is a biconvex lens with the positive focal power, the seventh lens is a falcate lens with the negative focal power, the eighth lens is a biconvex lens with the positive focal power, and the eighth lens is connected with a color filter. The visible light wave band and the near-infrared wave band guided in by the lens are focused in the same focal plane, so that the novel ultra wide angle lens can conduct clear imaging in the day and night modes.
