Abstract
The present invention provides a camera optical lens including, from an object side to an image side, a first lens, a second lens, a third lens, a third lens, a fourth lens, a fifth lens, a sixth lens, a seventh lens and a eighth lens. The first, third, fifth and seventh lens have positive refractive power, while the second, fourth, sixth and eighth lens have negative refractive power. The camera optical lens satisfies the following conditions: 0.70≤f1/f≤1.00; −20.00≤f4/f≤3.50; and 2.30≤f5/f≤4.50; where f denotes a focal length of the camera optical lens, and f1, f4 and f5 respectively denote a focal length of the first lens, the fourth lens and the fifth lens. The camera optical lens in the present disclosure satisfies a design requirement of large aperture, wide angle and ultra-thinness while having good optical functions.
