Abstract

The invention relates to a field of an optical lens and discloses a shooting optical lens. The shooting optical lens comprises an aperture, a first lens having positive refraction power, a second lens having negative refraction power, a third lens having positive refraction power, a fourth lens having negative refraction power and a fifth lens having negative refraction power, wherein the shooting optical lens further satisfies expressions as follows, 0.45<f1 / f<0.55, 0.85<f2 / f< 0.75, 2.0<f3 / f<2.3, 3.4<f4 / f< 3, 1.3<f5 / f< 1.1 and 0.2<f2 / f4<0.3 . The shooting optical lens is advantaged in that design demands of low TTL and large aperture can be satisfied, and excellent sensitivity is realized.

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 -OxideSemiconductor 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 good Miniaturized camera lenses with image quality have become the mainstream in th...
