Optical camera lens

An optical camera lens, from an object side to an image side, successively comprising:

• an aperture;
• a first lens having positive refraction power;
• a second lens having negative refraction power;
• a third lens having negative refraction power;
• a fourth lens having positive refraction power;
• and
• a fifth lens having negative refraction power;
• wherein a focal length of the integral optical camera lens is f, a focal length of the first lens is f1, a focal length of the second lens is f2, a focal length of the third lens is f3, a focal length of the fourth lens is f4 and a focal length of the fifth lens is f5, which satisfy following relational expressions:
• 0.70<f1/f<0.80;
• −1.9<f2/f<−1.7;
• −18<f3/f<−13;
• 0.59<f4/f<0.63;
• −0.52<f5/f<−0.48;
• wherein an abbe number of the third lens is v3, a refractive index of the third lens is n3, a refractive index of the fifth lens is n5, a thickness of the third lens is d5, a total track length of the optical camera lens is TTL, which satisfy following relational expressions:
• 17<v3/n3<20;
• 1.08<n3/n5<1.20;
• 0.03<d5/TTL<0.04;
• 1.08<(f3−f4)/(f3+f4)<1.10.
