Patent attributes
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 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: 5.00≤f4/f2≤10.00; and 7.50≤f3/f5≤50.00, where f2 denotes a focal length of the second lens; f3 denotes a focal length of the third lens; f4 denotes a focal length of the fourth lens; and f5 denotes a focal length of the fifth lens.
