The camera lens is only cleaned when it is very necessary, and a little dust will not affect the image quality. When cleaning, you should use a soft brush, such as a brush made of mink hair or blow a balloon to remove dust. Fingerprints do great harm to the lens and should be removed as soon as possible. When not using the lens, be sure to cover the lens to reduce the number of cleaning.

Wet the lens cloth (high-quality glasses cloth or suede is better) slightly, or blow air into the lens, gently wipe the lens surface with the lens stroke circle, and finally dry the lens with the lens cloth in the same way. And the whole cleaning process should be light, because the surface of the camera lens is quite delicate.

According to the author's experience, it is better to use high-quality glasses cloth or suede, because the material and quality of some lens paper are really flattering, and it feels rough, and there will be scraps of paper when wiping. Can you rest assured that something like this is used to wipe the lens? Not to mention the paper towels we use in our daily life. The better the digital camera lens, the less you can wipe it with inferior paper!

Another important tool for the lens is the ear washing ball mentioned above, which is the kind of watch repair. I prefer to use a lens pen. There are some brands of cleaning liquids on the market now. Who knows what the chemical composition is? So I suggest using anhydrous alcohol or medical alcohol, because they will not damage the coating of the lens. Teacher Ma gives your uncle extra points. Hahahaha.
