Abstract
The present disclosure discloses a camera optical lens. The camera optical lens including, in an order 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 further satisfies following conditions: 1.10≤f1/f≤3.00; and 3.50≤R7/d7≤6.50; where f denotes a focal length of the optical camera lens; f1 denotes a focal length of the first lens; R7 denotes a curvature radius of an object side surface of the fourth lens and d7 denotes an on-axis thickness of the fourth lens. The camera optical lens can achieve a high performance while obtaining a low TTL.
