Optical camera lens with large aperture and large image surface

The invention discloses an optical camera lens with a large aperture and a large image surface. The optical camera lens with the large aperture and the large image surface comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, a seventh lens and an eighth lens, wherein the first lens, the second lens, the third lens, the fifth lens, the sixth lens, the seventh lens and the eighth lens are plastic lens. The weight of the overall camera lens is effectively lightened; the fourth lens is a glass lens; further, a diaphragm is arranged between the third lens and the fourth lens, so that the camera lens provided by the invention has the aperture up to F1.2 and the imaging image surface up to 1 inch; meanwhile, the photographic requirements that the clear shooting can be carried out in a low-illumination environment and a photograph is high in resolution ratio when being enlarged are met; the pixel of a shot photograph can be up to 20,000,000 to 40,000,000; the optical camera lens with the large aperture and the large image surface can be used for the fields of lenses for mobile-phone photographing, monitoring photographing and the like.
