The optical system includes in sequence from the object side to the image side along the optical axis: the first lens, which has negative refractive power; the second lens, which has positive refractive power; the third lens, which has negative refractive power; the fourth lens, which has positive refractive power ; The fifth lens has negative refractive power; the optical system satisfies the conditional formula: 0.5

Description

technical field [0001] The invention belongs to the technical field of optical imaging, and in particular relates to an optical system, a lens module and an electronic device. Background technique [0002] Today, with the rapid development of technology, consumers have higher and higher requirements for imaging quality of mobile electronic products. In order to meet high-end imaging systems and achieve wide-angle shooting effects, the five-piece lens can be used as one of the accessories for various types of camera-capable portable electronic devices. However, the existing five-piece lens cannot meet the requirements of a large field of view and high imaging quality at the same time. SUMMARY OF THE INVENTION [0003] The purpose of this application is to provide an optical system, a lens module and an electronic device for solving the above technical problems. [0004] The present invention provides an optical system, comprising in sequence from the object side to the im...
