Abstract
The present disclosure provides a camera optical lens. The camera optical lens includes, from an object side to an image side: an aperture; 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 negative refractive power; a fifth lens having a positive refractive power; a sixth lens having a negative refractive power; and a seventh lens having a negative refractive power. The camera optical lens satisfies following conditions: 9.00≤f3/f≤30.00; and 2.90≤v1/v2≤5.00, where f denotes a focal length of the camera optical lens; f3 denotes a focal length of the third lens; v1 denotes an abbe number of the first lens; and v2 denotes an abbe number of the second lens.
