PURPOSE: A camera lens having optically aberration characteristic is provided to conveniently design a lens module by arranging an aperture on an object side nearer than a first lens. CONSTITUTION: A first lens(10) has a positive pole(+). A second lens(20) has a negative pole(-). A third lens(30) has the positive pole. A fourth lens(40) has the positive pole. A fifth lens(50) has negative pole and at least one more inflection point. An aperture(5) is located on in the object side nearer than the first lends. The aperture, first lens, second lens, third lens, fourth lens and fifth lens are arranged from the object side. A filter(60) blocks the infrared ray. |
