Recently a camera lens unit having a lens of high resolution, using a lens which has positive(+) refractive power and five lenses each of which has negative(-) refractive power, is being developed. However, the camera lens unit of five lens structure has a weakness that the optical features or aberrational features which a user wants are not clearly found on particular conditions. The purpose of the present invention which is designed to solve the problem is to provide the camera lens unit which is comprised of five lenses, has a short length to be fit to a module for a small camera, and provides a thin film camera optical system of high resolution. |
