Abstract
Provided is a camera optical lens, which includes a first lens having a negative refractive power, a second lens having a positive 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, and a sixth lens having a negative refractive power. The camera optical lens satisfies −10.00≤f1/f≤−4.00, 0.40≤f5/f≤0.70, and 8.00≤d5/d6≤15.00, where f denotes a focal length of the camera optical lens; f1 denotes a focal length of the first lens; f5 denotes a focal length of the fifth lens; d5 denotes an on-axis thickness of the third 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. The camera optical lens has good optical performance and satisfies design requirements for ultra-thin, wide-angle lenses having large apertures.
