Abstract
A camera optical lens is provided, including from an object side to an image side: a first lens having negative refractive power; a second lens having positive 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: −6.00≤f3/f≤−3.70; −3.00≤R2/R1≤−0.80; 2.10≤d6/d8≤6.00; and 3.00≤d3/d4≤12.00. The above camera optical lens may meet design requirements on large aperture, wide angle and ultra-thinness, while maintaining a high imaging quality.
