Camera optical lens

Abstract

Provided is a camera optical lens including a first lens having a positive refractive power, a second lens having a positive refractive power, a third lens having a negative refractive power, a fourth lens, a fifth lens having a positive refractive power, and a sixth lens. The camera optical lens satisfies: 5.00≤f1/f≤20.00; 12.00≤(R7+R8)/(R7−R8); and 2.00≤(R11+R12)/(R11−R12)≤8.00, where f denotes a focal length of the camera optical lens; f1 denotes a focal length of the first lens; R7 and R8 denote curvature radiuses of an object side surface and an image side surface of the fourth lens, respectively; and R11 and R12 denote curvature radiuses of an object side surface and an image side surface of the sixth lens, respectively. The camera optical lens can achieve good optical performance while satisfying design requirements for ultra-thin, wide-angle lenses having large apertures.
