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: −3.00≤f1/f2≤−1.50; 1.80≤d3/d4≤4.00; 2.50≤R7/R8≤6.00; and f3/f≤−5.00. The above camera optical lens may meet design requirements for large aperture, wide angle and ultra-thinness, while maintaining a high imaging quality.
