Abstract

The present disclosure provides an ultrathin 5-lensed camera lens having excellent optical characteristics, a field of view being greater than 85°, and bright F number. Starting from the object side, configuration of the five lenses is as follows in order: a first lens with positive refractive power, a second lens with positive refractive power, a third lens with negative refractive power, a fourth lens with positive refractive power and a fifth lens with negative refractive power. The lenses meet designated conditional formulas.

Claims (25)

1. A camera lens, comprising in order from an object side: a first lens with positive refractive power, a second lens with positive refractive power, a third lens with negative refractive power, a fourth lens with positive refractive power and a fifth lens with negative refractive power, which meet the following conditional formulas:

28.00≤ v 2− v 3≤40.00   (1);

28.00≤ v 2− v 4≤40.00   (2);

28.00≤ v 2− v 5≤40.00   (3);

1.80≤ f 2/ f 4≤2.00   (4);

0.63≤ d 3/ d 1≤0.66   (5);

Wherein,

v2: Abbe number of the second lens;

v3: Abbe number of the third lens;

v4: Abbe number of the fourth lens;

v5: Abbe number of the fifth lens;

f2: focal distance of the second lens;

f4: focal distance of the fourth lens;

d1: center thickness of the first lens;

d3: center thickness of the second lens.

2. The camera lens according to claim 1 , wherein it meets the following conditional formula (6):

2.95≤ R 3/ R 4≤3.20   (6);

wherein,

R3: curvature radius of object side surface of the second lens;

R4: curvature radius of image side surface of the second lens.

3. The camera lens according to claim 1 , wherein it meets the following conditional formula (7):

−2.70≤ R 5/ R 6≤−1.00   (7);

wherein,

R5: curvature radius of object side surface of the third lens;

R6: curvature radius of image side surface of the third lens.
