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 positive refractive power; a third lens having positive refractive power; a fourth lens having negative 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: 1.50≤f2/f≤5.00; −9.50≤(R9+R10)/(R9−R10)≤−1.20; −2.00≤f7/f≤−0.60, where f denotes focal length of the camera optical lens; f2 denotes focal length of the second lens; f7 denotes focal length of the seventh lens; R9 denotes central curvature radius of object side surface of the fifth lens; and R10 denotes central curvature radius of image side surface of the fifth lens. The above camera optical lens may meet design requirements for large aperture, wide angle and ultra-thinness, while maintaining good imaging quality.
