Function of digital camera filter

V can filter ultraviolet rays, but it will also affect the light transmittance. Especially for optical products, the higher the transmittance, the better. Therefore, in a good environment, UV will not be installed for shooting.

Therefore, the biggest role of ultraviolet rays is to protect lenses. Especially in high humidity and dusty environment, install a UV protection main lens. After all, UV is only a few tens to a hundred dollars, and it is not so difficult to damage it.

In addition, it can effectively prevent novice or ignorant friends from touching the camera by mistake and leaving fingerprints.
