Abstract
A camera optical lens is provided, including, from an object side to an image side in sequence: a first, second, third, fourth and fifth lens respectively having positive, negative, negative, positive and negative refractive power, which satisfies conditions: −0.17≤f1/f2≤−0.12; 1.80≤d1/d2≤2.20; 0.15≤d6/d8≤0.20; 8.00≤(R3+R4)/(R3−R4)≤10.00. f1 and f2 respectively denote focal length of the first and second lens; d1 denotes on-axis thickness of the first lens; d2, d6 and d8 respectively denote on-axis distance from image-side surface of the first lens to object-side surface of the second lens, from image-side surface of the third lens to object-side surface of the fourth lens and from image-side surface of the fourth lens to object-side surface of the fifth lens; R3 and R4 respectively denote curvature radius of object-side surface and image-side surface of the second lens. The camera optical lens can satisfy design requirement of large aperture, wide-angle and ultra-thinness while having good optical functions.
