Patent attributes
A camera optical lens includes first to fifth lenses from an object side to an image side, which are first and fourth lenses having positive refractive power, and second, third and fifth lenses having negative refractive power. The camera optical lens satisfies 0.90≤f1/f≤1.30; −5.00≤f3/f≤−2.50; 10.00≤d1/d2≤25.00; and 0≤(R7+R8)/(R7−R8)≤0.90, where f, f1 and f3 respectively denote focal lengths of the camera optical lens, the first lens, and the third lens, R7 denotes a curvature radius of an object side surface of the fourth lens, R8 denotes a curvature radius of an image side surface of the fourth lens, d1 denotes an on-axis thickness of the first lens, and d2 denotes an on-axis distance from an image side surface of the first lens to an object side surface of the second lens. The camera optical lens has good optical performance and satisfies design requirements of a large angle, a wide angle and ultra-thinness.
