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≤f/f≤5 0.00; −9.50≤(R+R)/(R−R)≤−1.20; −2.00≤f/f≤−0.60, where f denotes focal length of the camera optical lens; fdenotes focal length of the second lens; fdenotes focal length of the seventh lens; Rdenotes central curvature radius of object side surface of the fifth lens; and Rdenotes 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.
