Abstract
The present disclosure discloses a camera optical lens including eight lenses which are, 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 having a positive refractive power, a fourth lens having a positive refractive power, a fifth lens having a negative refractive power, a sixth lens having a positive refractive power, a seventh lens having a negative refractive power and an eight lens having a negative refractive power, which satisfies following conditions: 0.95≤f/TTL; −3.50≤f2/f≤−1.80; and 3.00≤(R9+R10)/(R9−R10)≤30.00; where f denotes a focal length of the camera optical lens. The camera optical lens can achieve good optical performance while meeting the design requirement for large aperture, long focal length and ultra-thinness (in a camera optical lens with the long focal length).
