       BACKGROUND 
       [0002]    In recent years, a variety of cameras equipped with CCD, CMOS or other camera elements are widely popular. Along with the development of miniature and high performance camera elements, the ultrathin and high-luminous flux F wide-angle camera lens with excellent optical characteristics is needed in market. 
         [0003]    The technology related to the camera lens composed of 5 ultrathin and high-luminous flux f wide angle lenses with excellent optical properties is developed gradually. The camera lens mentioned in the proposal is composed of 5 lenses which are lined up in turn from the object side as follows: a first lens with positive refractive power, a second lens with negative refractive power, a third lens with negative refractive power, a fourth lens with positive refractive power, a fifth lens with negative refractive power. 
         [0004]    The camera lens in the embodiment 4 to 6 in the special bulletin No.2014-197105 is composed of 5 lenses described above, but the distribution of the refractive power of the first lens, the second lens and the third lens, as well as the shape of the fourth lens are inadequate. Fno≧2.64, 2ω≦65.0° wide angle is not sufficient and Fno luminous flux are insufficient. 
         [0005]    The camera lens described in the embodiments 1-5 of JP patent publication No. 2014-197104 is composed of 5 lenses described above, but the refractive power of the first lens and the shape of the fourth lens are inadequate. The degree of wide angle 2 Ω≦71.4° is inadequate. 
         [0006]    For this reason, it is necessary to provide a novel camera lens to overcome the shortcomings above.

     DETAILED DESCRIPTION 
       [0021]    The present disclosure will be described in detail below with reference to the attached drawings and exemplary embodiments thereof. 
         [0022]      FIG. 1  is an illustrative structure of a camera lens of one embodiment of the present invention. The camera lens LA comprises 5 lenses which are lined up in turn from the object side to the image side as follows: a stop S 1 , a first lens L 1 , a second lens L 2 , a third lens L 3 , a fourth lens L 4  and a fifth lens L 5 . A glass plate GF is provided between the fifth lens L 5  and the imaging plane. The glass plate GF is a cover glass or a light filter with IR cut-off filtration and other functions, or alternatively, the glass plate GF is not provided between the fifth lens L 5  and the imaging plane. 
         [0023]    The first lens L 1  has positive refractive power. The second lens L 2  has negative refractive power. The third lens L 3  has negative refractive power. The fourth lens L 4  has positive refractive power. The fifth lens L 5  has negative refractive power. In order to correct aberration better, the surface of  5  lenses is designed to be non-spherical shape. 
         [0024]    The camera lens LA satisfies the following conditions (1)-(6): 
         [0000]      0.70≦= f 1/ f≦ 0.78  (1)
 
         [0000]      −1.90≦ f 2/ f≦− 1.30  (2)
 
         [0000]      −400.00≦ f 3/ f≦− 65.00  (3)
 
         [0000]      −1.20≦( R 1+ R 2)/( R 1− R 2)≦−1.00  (4)
 
         [0000]      1.20≦( R 7+ R 8)/( R 7− R 8)≦1.90  (5)
 
         [0000]      0.08≦ d 6/ f≦ 0.13  (6)
 
         [0000]    In which:
 
f: Overall focal distance of the lenses.
 
f 1 : The focal distance of the first lens.
 
f 2 : The focal distance of the second lens.
 
f 3 : The focal distance of the third lens.
 
R 1 : The curvature radius of the object side of the first lens.
 
R 2 : The curvature radius of the image side of the first lens.
 
R 7 : The curvature radius of the object side of the fourth lens.
 
R 8 : The curvature radius of the image side of the fourth lens.
 
d 6 : The axial distance from the image side of the third lens to the object side of the fourth lens.
 
         [0025]    The condition (1) specifies the positive refractive power of the first lens L 1 . When exceeding the lower limit of the condition (1), the first lens L 1  has too great positive refractive power to correct the aberration and other issues and also not conducive to wide-angle development of lens. On the contrary, when exceeding the upper limit, the first lens has too weak refractive power to realize the ultrathin target of lens. 
         [0026]    The condition (2) specifies the negative refractive power of the second lens L 2 . If the value exceeds the limit of the condition (2), along with the wide angle and ultrathin development of the lens, it is difficult to correct the axial and abaxial chromatic aberration. 
         [0027]    The condition (3) specifies the negative refractive power of the third lens L 3 . If the value exceeds the limit of the condition (3), along with the wide angle and ultrathin development of the lens, it is difficult to correct the axial and abaxial chromatic aberration. 
         [0028]    The condition (4) specifies the shape of the first lens L 1 . If the value exceeds the limit of the condition (4), along with the wide angle and ultrathin development of the lens, it is difficult to correct the spherical aberration and other higher aberration issues. 
         [0029]    The condition (5) specifies the shape of the fourth lens L 4 . By satisfying the condition (5), the wide angle and ultrathin development of the lens is effective. 
         [0030]    The condition (6) specifies the proportion of the distance between the image side of the third lens L 3  and the object side of the fourth lens L 4  to the overall focus distance of the lenses. If the value exceeds the limit of the condition (6), it is not conducive to the wide angle and ultrathin development of the lens. 
         [0031]    The camera lens further meets the following condition (7): 
         [0000]      0.07≦ d 8/ f≦ 0.15  (7)
 
         [0000]    In which:
 
f: Overall focal distance of the lenses.
 
d 8 : The axial distance from the image side of the fourth lens to the object side of the fifth lens.
 
         [0032]    The condition (7) specifies the proportion of the distance between the image side of the fourth lens L 4  and the object side of the fifth lens to the overall focus distance of the lenses. If the value exceeds the limit the condition (7), it is not conducive to the wide angle and ultrathin development of the lenses. 
         [0033]    The fourth lens L 4  has positive refractive power and satisfies following condition (8): 
         [0000]      0.50≦ f 4/ f≦ 0.80  (8)
 
         [0000]    In which:
 
f: Overall focal distance of the lenses
 
f 4 : The focal distance of the fourth lens.
 
         [0034]    The condition (8) specifies the positive refractive power of the fourth lens L 4 . By satisfying the condition (8), the lens can realize the wide angle and ultrathin development target. 
         [0035]    The fifth lens L 5  has negative refractive power and satisfies the following condition (9): 
         [0000]      ˜0.80≦ f 5/ f≦˜ 0.45  (9)
 
         [0000]    In which:
 
f: Overall focal distance of the lenses.
 
f 5 : The focal distance of the fifth lens.
 
         [0036]    The condition (9) specifies the negative refractive power of the fifth lens L 5 . By satisfying the condition (9), the lens can realize wide-angle and ultrathin target and can ensure the axial distance from the image side to the imaging plane of the fifth lens. 
         [0037]    As five lenses of the camera lens LA have the composition described above and meet all conditions, it is possible to produce a camera lens composed of  5  ultrathin and high-luminous flux lenses with excellent optical properties, TTL (optical length)/IH (image height)≦1.35, wide angle 2ω≧74°, Fno≦2.2.
