Abstract
The present disclosure discloses a camera optical lens. The camera optical lens includes, from an object-side to an-image side: a first lens having a positive refractive power, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, a seventh lens and an eight lens, which satisfies following conditions: 0.95≤f/TTL; −3.50≤f2/f≤−1.80; and 0.30≤(R5+R6)/(R5−R6)≤0.90; where TTL denotes a total optical length from an object-side surface of the first lens to an image surface of the camera optical lens along an optic axis; f denotes a focal length of the camera optical lens; f2 denotes a focal length of the second lens; R5 denotes a curvature radius of an object-side surface of the third lens; R6 denotes a curvature radius of an image-side surface of the third lens. The camera optical lens can achieve good optical performance while meeting the design requirement for long focal length and ultra-thinness.
