Abstract
The present invention provides a camera optical lens including, from an object side to an image side, a first lens having a positive refractive power, a second lens having a negative refractive power, a third lens, a fourth lens having a positive refractive power, a fifth lens having a negative refractive power, a sixth lens having a negative refractive power, a seventh lens having a positive refractive power and a eighth lens having a negative refractive power. The camera optical lens satisfies the following conditions: 0.65≤f1/f≤0.85, 2.00≤f4/f≤5.00, and −5.50≤f5/f≤−2.50; where f, f1, f4 and f5 respectively denote a focal length of the camera optical lens, the first lens, the fourth lens and the fifth lens. The camera optical lens in the present disclosure has characteristics of large aperture, wide angle and ultra-thinness while having good optical functions.
