OPTICAL CAMERA LENS

An optical camera lens (10), which relates to the field of optical lenses, sequentially comprises, from an object side to an image side, a first lens (L1) having a positive refractive power, a second lens (L2) having a negative refractive power, a third lens (L3) having a positive refractive power, a fourth lens (L4) having a positive refractive power, a fifth lens (L5) having a negative refractive power, a sixth lens (L6) having a positive refractive power and a seventh lens (L7) having a negative refractive power. The optical camera lens (10) has an overall focal length f, the second lens (L2) has a focal length f2, the fifth lens (L5) has a focal length f5, the seventh lens (L7) has a focal length f7, an object side face of the fourth lens (L4) has a radius of curvature R7, an image side face of the fourth lens (L4) has a radius of curvature R8, and the following relational expressions are met: -4.00 ≤ f2/f ≤ -1.50, 3.20 ≤ f5/f7 ≤ 7.50, and R7/R8 ≤ -3.20. The optical camera lens (10) has good optical prope
