Abstract
(EN)
A camera optical lens (10), successively comprising from an object side to an image side: an aperture (S1), a first lens (L1) that has a positive refractive power, a second lens (L2) that has a negative refractive power, a third lens (L3) that has a negative refractive power, a fourth lens (L4) that has a positive refractive power, and a fifth lens (L5) that has a negative refractive power. The focal length of the camera optical lens (10) is f, the unit of the focal length is millimeters, the focal length of the first lens (L1) is f1, the focal length of the fourth lens (L4) is f4, the radius of curvature of an object side surface of the fifth lens (L5) is R9, the radius of curvature of an image side surface of the fifth lens (L5) is R10, and the following relationships are satisfied: 1≤f1/f≤1.1; 0.4≤f4/f≤0.6; and 11≤R9/R10≤12. The present camera optical lens (10) may meet the design requirements of a large aperture, being ultra-thin and wide-angled while having a good optical performance.
