Abstract
A camera optical lens is provided, including from an object side to an image side: a first lens having positive refractive power; a second lens having negative refractive power; a third lens having negative refractive power; a fourth lens having positive refractive power; and a fifth lens having negative refractive power. The camera optical lens satisfies following conditions: −5.00≤f2/f≤−2.50; 2.00≤d5/d6≤4.00; −4.00≤R7/R8≤−1.30; and −2.00≤(R1+R2)/(R1−R2)≤−1.00. The above camera optical lens may meet design requirements for large aperture, wide angle and ultra-thinness, while maintaining a high imaging quality.
