[0079] Please refer to the accompanying drawings, the present invention provides a camera optical lens 10 . figure 1 Shown is the imaging optical lens 10 of the first embodiment of the present invention, and the imaging optical lens 10 includes eight lenses. Specifically, the imaging optical lens 10 includes, from the object side to the image side in sequence: a first lens L1 with a negative refractive power, a second lens L2 with a positive refractive power, an aperture S1, and a third lens with a positive refractive power. A lens L3, a fourth lens L4 having a negative refractive power, a fifth lens L5, a sixth lens L6, and a seventh lens L7. An optical element such as an optical filter (filter) GF may be disposed between the seventh lens L7 and the image plane Si.
[0080] The first lens L1 is made of plastic material, the second lens L2 is made of plastic material, the third lens L3 is made of plastic material, the fourth lens L4 is made of plastic material, the fifth lens...
