Document Type and Number:
WIPO Patent Application WO/2021/127843
Kind Code:
A1
Abstract:
An optical camera lens (10) sequentially comprising, from an object side to an image side, a first lens (L1) having a positive refractive power, a second lens (L2) having a negative refractive power, a third lens (L3) having a positive refractive power, a fourth lens (L4) having a positive refractive power, a fifth lens (L5) having a negative refractive power, a sixth lens (L6) having a negative refractive power, and a seventh lens (L7) having a positive refractive power, wherein the following expressions are satisfied: -1.00 ≤ f5 / f ≤ -0.30; 3.00 ≤ (R5 + R6) / (R5 - R6) ≤ 20.00; 3.00 ≤ d10 / d11 ≤ 10.00. The camera optical lens (10) has good optical performance and meets the design requirements for large aperture, long focal length, and being ultra-thin.
