Abstract
The present invention relates to the field of optical lenses and provides a camera optical lens sequentially including, from an object side to an image side: 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; a fifth lens; a sixth lens having a positive refractive power; and a seventh lens having a negative refractive power. The camera optical lens satisfies following conditions: 2.80≤v1/v2≤4.50; and −10.00≤f3/f≤−3.00, where f denotes a focal length of the camera optical lens; f3 denotes a focal length of the third lens; and v1 and v2 denote abbe numbers of the first and second lenses, respectively. The camera optical lens according to the present invention can achieve high optical performance while satisfying design requirements for ultra-thin, wide-angle lenses having large apertures.
