Camera optical lens

Abstract

A camera optical lens is provided, including from an object side to an image side: a first lens having positive refractive power; a second lens having negative refractive power; a third lens having positive refractive power; a fourth lens having positive refractive power; a fifth lens having negative refractive power; a sixth lens having positive refractive power; and a seventh lens having negative refractive power. The camera optical lens satisfies following conditions: −4.00≤f2/f≤−1.50; 3.20≤f5/f7≤7.50; R7/R8<−3.20, f denotes total focal length of the camera optical lens; f2 denotes focal length of second lens; f5 denotes focal length of fifth lens; f7 denotes focal length of seventh lens; R7 denotes curvature radius of object side surface of fourth lens; R8 denotes curvature radius of image side surface of fourth lens. The above camera optical lens may meet design requirements for large aperture, wide angle and ultra-thinness, while maintaining good imaging quality.
