　　The principle of the light-shielding ring is based on the principle of physical phenomena (small hole imaging), and the processing requirements are relatively strict. Therefore, the requirements for materials also have higher-level requirements.

　　The hood can block and absorb light that degrades the image quality and improve the image quality. By the way, protect the lens in case of accidental bumps.

　　The hood is made of metal, and the most common one is plastic. If it is scratched, as long as it does not deform, it will continue to be used.

　　The shading ring can be adjusted, and the size can control the brightness. If the light is weak, turn it up, and if the light is strong, turn it down.
