Abstract

The invention provides a camera shooting optical lens, which sequentially comprises a first lens with positive refractive power, a second lens with negative refractive power, a third lens, a fourth lens with positive refractive power and a fifth lens with negative refractive power from an object side to an image side, and meets the following relational expressions:-5.00 < = f2 / f < =-2.50; 0.50 < =f4 / f < = 0.75; 0.20 < = (R9 + R10) / (R9-R10) < = 1.00; 18.00 < = | f3 | / f; 5.00 < = d1 / d2 < = 15.00. The camera shooting optical lens has good optical performance and meets the design requirements oflarge aperture, wide angle and ultra-thinness.

Description

【Technical field】 [0001] The invention relates to the field of optical lenses, in particular to an imaging optical lens suitable for portable terminal devices such as smart phones and digital cameras, and imaging devices such as monitors and PC lenses. 【Background technique】 [0002] With the development of camera technology, camera optical lenses are widely used in various electronic products, such as smart phones, digital cameras and so on. For the convenience of portability, people are increasingly pursuing thinner and lighter electronic products. Therefore, miniaturized camera optical lenses with good imaging quality have become the mainstream of the current market. [0003] The camera optical lenses on traditional electronic products mostly adopt four-piece, five-piece, six-piece or even seven-piece lens structures. The shape setting is insufficient, resulting in insufficient wide-angle and ultra-thin imaging optical lenses. [0004] Therefore, it is necessary to prov...
