Abstract
A camera optical lens includes from an object side to an image side: a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens. The camera optical lens satisfies: −1.00≤f2/f≤−0.60; 1.50≤R6/R5 and 2.00≤d4/d5≤10.00, where f denotes a focal length of the camera optical lens, f2 denotes a focal length of the second lens, R5 denotes a central curvature radius of an object side surface of the third lens, R6 denotes a central curvature radius of an image side surface of the third lens, d4 denotes an on-axis distance from an image side surface of the second lens to an object side surface of the third lens, and d5 denotes an on-axis thickness of the third lens. The camera optical lens of the application has good optical performance and meets the design requirement for a long focal length.
