Camera optical lens

Abstract

Provided is a camera optical lens including first to fifth lenses. The camera optical lens satisfies: 0.35≤f1/f≤0.65 ; 2.00≤f5/f≤4.00; 0.90≤d6/d8≤1.30; and −10.00≤(R5+R6)/(R5−R6)≤−2.00, 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; d6 denotes an on-axis distance from an image side surface of the third lens to an object side surface of the fourth lens; d8 denotes an on-axis distance from an image side surface of the fourth lens to an object side surface of the fifth lens; and R5 and R6 respectively denote curvature radiuses of an object side surface and an image side surface of the third lens. The camera optical lens can achieve good optical performance while satisfying design requirements for ultra-thin, long-focal-length lenses having large apertures.
