[0054] (First embodiment)
[0055] Please refer to the drawings, the present invention provides a camera optical lens 10. figure 1 Shown is an imaging optical lens 10 according to the first embodiment of the present invention. The imaging optical lens 10 includes six lenses. Specifically, the imaging optical lens 10 includes in order from the object side to the image side: an aperture S1, a first lens L1 with positive refractive power, a second lens L2 with negative refractive power, and a third lens with negative refractive power. The lens L3, the fourth lens L4, the fifth lens L5, and the sixth lens L6 having positive refractive power. An optical element such as an optical filter GF may be provided between the sixth lens L6 and the image plane Si.
[0056] In this embodiment, the focal length of the imaging optical lens 10 is defined as f, the focal length of the first lens L1 is f1, and the following relationship is satisfied: 0.40≤f1 / f≤0.60; the first lens L1 is defined The r...
