Abstract
Provided is a camera optical lens including first to sixth lenses. The camera optical lens satisfies following conditions: 0.45≤f1/f≤0.80; −10.00≤R9/R10≤−1.50; and 0.35≤d3/d4≤0.70, where f denotes a focal length of the camera optical lens; f1 denotes a focal length of the first lens; R9 denotes a curvature radius of an object side surface of the fifth lens; R10 denotes a curvature radius of an image side surface of the fifth lens; d3 denotes an on-axis thickness of the second lens; and d4 denotes an on-axis distance from an image side surface of the second lens to an object side surface of the third lens. The camera optical lens has good optical performance while achieving ultra-thin, long-focal-length lenses having large apertures.
