Document Type and Number:
Japanese Patent JP6846094
Kind Code:
B2
Abstract:
The present disclosure a camera optical lens is provided including, from an object side to an image side: a first lens having a positive refractive power; a second lens having a negative refractive power; a third lens having a negative refractive power; a fourth lens having a positive refractive power; and a fifth lens having a negative refractive power. The camera optical lens satisfies following conditions: 0.40≤f1/f≤0.48; −0.75≤f2/f≤−0.50; 1.20≤f4/f≤3.20; −1.40≤f5/f≤−1.10; 6.00≤d1/d2≤8.00; 0.80≤(R5+R6)/(R5−R6)≤6.50; and 3.00≤(R7+R8)/(R7−R8)≤10.00. The camera optical lens can achieve good optical performance while meeting the design requirements for long focal length and ultra-thinness.
