Camera Optical Lens

A camera optical lens comprising, from an object side to an image side in sequence:

• a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens and a seventh lens;
• wherein the camera optical lens further satisfies the following conditions:
• 1f1/f1.5;
• −2f3/f42;
• 1.7 n22.2;
• 1.7n72.2;
• 0.5(R13+R14)/(R13−R14)10;
• where
• f:
• the focal length of the camera optical lens;
• f1:
• the focal length of the first lens;
• f3:
• the focal length of the third lens;
• f4:
• the focal length of the fourth lens;
• n2:
• the refractive power of the second lens;
• n7:
• the refractive power of the seventh lens;
• R13:
• the curvature radius of object side surface of the seventh lens;
• R14:
• the curvature radius of image side surface of the seventh lens.
