Abstract
The present disclosure provides a camera optical lens satisfying following conditions: −0.50≤f1/f2≤−0.3; 50.00≤f3/f≤75.0; −2.40≤(f2+f5)/f≤−2.00; 0.70≤(R3+R4)/(R3−R4)≤0.95; 1.30≤(R7+R8)/(R7−R8)≤1.60; and 0.40≤(R9+R10)/(R9−R10)≤0.75; where f denotes a focal length of the camera optical lens; f1, f2, f3 and f5 respectively denote a focal length of a first, second, third and fifth lenses; R3 and R4 respectively denote a curvature radius of an object-side surface and an image-side surface of the second lens; R7 and R8 respectively denote a curvature radius of an object-side surface and an image-side surface of a fourth lens; and R9 and R10 respectively denote a curvature radius of an object-side surface and an image-side surface of the fifth lens. The camera optical lens in the present disclosure satisfies a design requirement of large aperture, wide angle and ultra-thinness while having good optical performance.
