The invention relates to the field of optical lenses, and discloses 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 with negative refractive power, a fourth lens and a fifth lens with negative refractive power from an object side to an image side; the focal length of the camera shooting optical lens is f, the focal length of the first lens is f1, the focal length of the third lens is f3, the on-axis distance from the image side surface of the third lens to the object side surface of the fourth lens is d6, the on-axis thickness of the fourth lens is d7, the center curvature radius of the object side surface of the fifth lens is R9, the center curvature radius of the image side surface of the fifth lens is R10, and the fifth lens satisfies the following relational expressions: 0.30<=f1 / f<=0.50; -4.00<=f3 / f<=-1.20; 2.00<=d6 / d7<=8.00; 3.00<=R9 / R10<=10.00. The camera shootingoptical lens provided by the invention has good optical performance and also meets the design requirements of long focal length 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] In recent years, with the rise of smart phones, the demand for miniaturized photographic lenses has been increasing, and the photosensitive devices of general photographic lenses are nothing more than photocoupled devices (Charge Coupled Device, CCD) or complementary metal oxide semiconductor devices (Complementary Metal -Oxide Semiconductor Sensor, CMOS Sensor), and due to the improvement of semiconductor manufacturing process technology, the pixel size of photosensitive devices has been reduced, and today's electronic products are developing with good functions and thin, light and small appearance. Therefore, it has Miniaturized camera lenses with good imaging quality have become the mainstream in...

Problems solved by technology

However, with the development of technology and the increase of diversified needs of users, the pixel area of ​​the photosensitive device is constantly shrinking, and the requirements of the system for imaging quality are constantly improving. Although the common five-element lens already has better optical performance, but its focal power, lens spacing and lens shape settings still have certain irrationality, resulting in a lens structure that has good optical performance and cannot meet the design requirements of long focal length and ultra-thin
