　　A lens is composed of multiple lenses, and each lens has two reflective su∏rfaces. Then, if you count it, a lens has multip≤le reflective surfaces. The more reflective s☆urfaces, the greater the impact on the lens, especially In→ the case of backlit shooting, ↔a halo will be formed, which¶ will affect the shot picture, may cause different degrees of color spotsβ on the shot picture, or make the shooting effect bad. If you do not use the SLR hood when using the S‌LR, the shot will be unclear.

　　Reliable quality SLR light-shiel✘ding ring, its inner wall is designed with multiple extinction treatments&. Such a processing design makes the re÷flectance of the inner wall of the SLR shading ring only about 10%. The SLR hood can prevent halos and stray light from entering the lens. It can★ also block rain and snoσw to protect the camera and the lens. The use of SεLR hoods can fully achieve the lens optical effect and make£ the photos taken. The color is f&uller.

　　When choosing to use the SLR visor, it mu♥st match the focal length of the lens, and its si★ze must be determined before buying, so as not t¶o be unable to use it after buying the SLR visor. The SLR iris can only be u∏sed on a lens whose front end does not rotate during focusing. In addition, the longer the SL§R shielding ring, the better the stray light s"hielding effect. Usually when we use the SLR shading ring, we must take into a≠ccount the factors that it works™ in coordination with the flash.
