How to wipe the UV mirror?

Lens water is carefully divided into three categories, namely, removing sticky dust, oil stain and mold. If you wipe it, you should also blow it first, then brush it to ensure that there is no dust on the UV mirror, then dip a little special lens water with absorbent cotton and rotate it from the middle, and then repeat the above actions with dry absorbent cotton. Cleaning the lens The role of UV mirror in photography, UV mirror is used to protect the lens and filter light. The lens in the camera is the most precious, so we should strengthen protection. Installing UV lenses can prevent some dust erosion, and of course it is very convenient to wipe, so don't worry about rubbing the lenses. The lens receives light when taking pictures, just like people look at objects. Seeing things in strong light makes you uncomfortable and tired. So you put on color filter glasses, and your eyes feel much more comfortable. That's because the lens blocks some strong ultraviolet rays and allows your eyes to accept external things under negative conditions. The same is true of the UV lens on this lens. On the one hand, it can effectively prevent the invasion of strong ultraviolet rays from causing image clarity, and on the other hand, it can prevent some air pollution from corroding the lens. When shooting film with a traditional camera. Due to the chemical characteristics of film, it is particularly sensitive to ultraviolet rays in the sun. In places with strong ultraviolet rays, photos taken with film are generally blue and white. Seriously affected the quality of photos. Adding a UV mirror in front of the lens can effectively filter ultraviolet rays and improve the clarity of photos. For mountain photography, aerial photography can make the distant scenery clearer and restore a more realistic and gorgeous picture. So at that time, the UV mirror became a necessary color filter. Because UV mirror can not only improve imaging, but also protect the lens from dust, fingerprints and other pollution. UV mirror is always installed in front of the lens without removal, which makes it the most widely used color filter. In the digital age, because CCD, the core imaging component of digital machine, is no longer too sensitive to ultraviolet rays like film, the filtering function of UV mirror is gradually weakened, but the damage of oil pollution, fingerprints and scratches to lens coating still exists. At this time, the UV mirror is more protective.
