     DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENTS 
     The present invention will hereinafter be described in detail with reference to exemplary embodiments. To make the technical problems to be solved, technical solutions and beneficial effects of present disclosure more apparent, the present disclosure is described in further detail together with the figures and the embodiments. It should be understood the specific embodiments described hereby is only to explain this disclosure, not intended to limit this disclosure. 
     A camera lens of the present disclosure shall be explained by referring to the design drawings. Referring to  FIG. 1 , a camera lens LA comprises seven piece lenses which are arranged in an order from an object side to an imaging surface side, including a first lens L 1 , a second lens L 2 , a third lens L 3 , a fourth lens L 4 , a fifth lens L 5 , a sixth lens L 6 , and a seventh lens L 7 . A glass plate GF is arranged between the seventh lens L 7  and the imaging surface. And a glass cover or an optical filter having the function of filtering IR can serve as the glass plate GF. Moreover, it shall be OK if no glass plate GF is arranged between the seventh lens L 7  and the imaging surface. 
     The first lens has positive refractive power; the second lens has negative refractive power; the third lens has negative refractive power; the fourth lens has positive refractive power; the fifth lens has positive refractive power; the sixth lens has positive or negative refractive power; and the seventh lens has negative refractive power. Moreover, the surfaces of the seven lenses should be designed as the aspheric shape preferably in order to correct the aberration well. 
     The camera lens LA satisfies the following conditions (1)˜(2):
 
0.10≦ f 2/ f 3≦0.50  (1);
 
0.30≦ f 5/ f≦ 1.00  (2); where,
 
f: overall focal distance of the camera lens
 
f2: focal distance of the second lens L 2 
 
f3: focal distance of the third lens L 3 
 
f5: focal distance of the fifth lens L 5 
 
     Ratio of focal distance of the second lens to the third lens both with negative refractive power is specified in condition (1). When exceeding range of condition (1), it is difficult to correct the chromatic aberration. 
     Therefore, numerical range of condition (1) should be set within the numerical range of the following condition (1-A) preferably,
 
0.15≦ f 2/ f 3≦0.25  (1-A)
 
     The positive refractive power of the fifth lens L 5  is specified in the condition (2). Moreover, the development of ultra-thin and wide angle trend of Fno≦1.8 cannot be implemented easily outside the range of the condition (2). 
     Therefore, numerical range of condition (2) should be set within the numerical range of the following condition (2-A) preferably,
 
0.58≦ f 5/ f≦ 0.73  (2-A)
 
     The sixth lens L 6  has positive or negative refractive power and meets the following condition (3).
 
10.00≦| f 6|/ f≦ 100.00  (3);
 
Where,
 
f: overall focal distance of the camera lens
 
f6: focal distance of the sixth lens L 6 
 
     The positive or negative refractive power of the sixth lens L 6  is specified in the condition (3). Moreover, the development of ultra-thin and wide angle trend of Fno≦1.8 cannot be implemented easily outside the range of the condition (3). 
     Therefore, numerical range of condition (3) should be set within the numerical range of the following condition (3-A) preferably,
 
14.00≦| f 6|/ f≦ 80.00  (3-A).
 
     Abbe numbers of the second lens L 2 , the third lens L 3  and the sixth lens L 6  meet following conditions (4)˜(6):
 
18.00≦ν2≦32.00  (4);
 
18.00≦ν3≦32.00  (5);
 
18.00≦ν6≦32.00  (6);
 
where,
 
ν2: abbe number of the second lens L 2 
 
ν3: abbe number of the third lens L 3 
 
ν6: abbe number of the sixth lens L 6 
 
     Abbe numbers of the second lens L 2 , the third lens L 3  and the sixth lens L 6  are specified in condition (4)˜(6). Correction of chromatic aberration on axis and outside of axis becomes easy by setting the numerical values within the range of conditions (4)˜(6). 
     Because seven lenses of camera Lens all have the stated formation and meet all the conditions, so it is possible to produce a camera lens which is composed of seven lenses with excellent optional properties, TTL(optical length)/IH(image height)≦1.55, ultrathin, wide angle 2ω≧75°, Fno≦1.8.

     The values in the embodiments 1 and 2 and the values corresponding to the parameters specified in the conditions (1)-(5) are shown in the subsequent Table 6. 
     The Embodiment 1 meets the conditions (1)-(5), as shown in Table 6. 
     Refer to  FIG. 3  for Longitudinal Aberration of the camera lens LA in the Embodiment 1, refer to  FIG. 4  for Lateral Color Aberration of it, and see  FIG. 5  for curvature of field and distortion of it. Further, the curvature of field S in the  FIG. 5  is the one in the sagittal direction, and T is the one in the direction of meridian, as well as in the Embodiment 2. Moreover, the camera lens LA in the embodiment 1 involves the ultra-thin wide angle camera lens having high luminous flux as shown in  FIGS. 3-5 , wherein 2ω=76°, TTL/IH=1.535, Fno=1.74; therefore, it is no wonder that this lens has these excellent optical properties. 
     Embodiment 2 
     The configuration structure diagram of the camera lens LA in the Embodiment 2 is shown in the  FIG. 6 . Moreover, the curvature radius of the object side surfaces and the image side surfaces, the center thicknesses of the lenses, the distances d among the lenses, the refractive powers nd and abbe numbers νd of the lens L 1 -L 7  in the Embodiment 2 are shown in the Table 3, wherein the camera lens LA is formed by the lens L 1 -L 7 ; and the conical coefficients k and aspheric coefficients are shown in the Table 4.

     The Embodiment 2 meets the conditions (1)-(5), as shown in Table 6. 
     See  FIG. 7  for Longitudinal Aberration of the camera lens LA in the Embodiment 2, see  FIG. 8  for Lateral Color Aberration of it, and see  FIG. 9  for curvature of field and distortion of it. Moreover, the total angle of view is involved in the camera lens LA in the Embodiment 2 as shown in  FIGS. 7-9 , and the lens refers to the ultra-thin wide angle camera lens having high luminous flux, wherein 2ω=80.0°, TTL/IH=1.498, Fno=1.78; therefore, it is no wonder that this lens has these excellent optical properties. 
     The values in all embodiments and the values corresponding to the parameters specified in the conditions (1)-(5) are shown in the Table 6. Moreover, the units including 2ω(°), f(mm), f1 (mm), f2 (mm), f3 (mm), f4 (mm), f5 (mm), f6 (mm), f7 (mm), TTL(mm), LB(mm) and IH(mm) are shown in the Table 5, respectively.
