Abstract
The present invention relates to the technical field of optical lens and discloses a camera optical lens satisfying the following conditions: −1.00≤(f1+f2)/f≤−0.10, 12.00≤d3/d4≤20.00, 5.00≤R5/d5≤11.00, 8.00≤d7/d8≤14.00; where f1 and f2 respectively denote a focal length of a first and second lenses, d3, d5 and d7 respectively denote an on-axis thickness of the second, third and fourth lenses, d4 denotes an on-axis distance from an image-side surface of the second lens to an object-side surface of the third lens, d8 denotes an on-axis distance from an image-side surface of the fourth lens to an object-side surface of the fifth lens, and R5 denotes a curvature radius of the object-side surface of the third lens. The camera optical lens has good optical functions and satisfies a design requirement of wide angle and ultra-thinness.
