Abstract:
An optical camera lens (10) comprises nine lenses in total, namely, a first lens (L1), a second lens (L2), a third lens (L3), a fourth lens (L4), a fifth lens (L5), a sixth lens (L6), a seventh lens (L7), an eighth lens (L8), and a ninth lens (L9) in sequence from an object side to an image side, the second lens (L2) having a negative refractive power. The optical camera lens (10) has a focal length f, the first lens (L1) has a focal length f1, the third lens (L3) has an on-axis thickness d5, the on-axis distance from an image side face of the third lens (L3) to an object side face of the fourth lens (L4) is d6, and the following relational expressions are met: 0.70 ≤ f1/f ≤ 1.90 and 2.00 ≤ d5/d6 ≤ 9.00. The optical camera lens (10) meets the design requirements of a large aperture, a wide angle, and an ultra-thin thickness while also having good optical properties.
