Abstract
The present disclosure relates to the field of optical lenses and 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 negative 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; and a seventh lens having a negative refractive power. The camera optical lens satisfies following conditions: 11.00≤f2/f1≤−6.00; and 5.00≤d7/d6≤10.00, where f1 denotes a focal length of the first lens; f2 denotes a focal length of the second lens; d7 denotes an on-axis thickness of the fourth lens; and d6 denotes an on-axis distance from an image side surface of the third lens to an object side surface of the fourth lens.
