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;
• the camera optical lens further satisfies the following conditions:
• −3f/1≤f−1;
• 1.7n32.2;
• 1f6/f710;
• 2(R1+R22)/(R1−R2)10;
• 1.7n2.2;
• where
• f:
• the focal length of the camera optical lens;
• f1:
• the focal length of the first lens;
• f6:
• the focal length of the sixth lens;
• f7:
• the focal length of the seventh lens;
• n3:
• the refractive power of the third lens;
• n6:
• the refractive power of the sixth lens;
• R1:
• curvature radius of object side surface of the first lens;
• R2:
• the curvature radius of image side surface of the first lens.
