How to clean the SLR camera lens [reprinted]

Posted on:2008-02-18

Most digital cameras cannot install protective filters, or installation is inconvenient. During Normal shooting, when the camera is exposed outside, it is easy to accidentally add dust, press a fingerprint, or leave some spit or something. Although the fingerprint, dust, and water stains on the lens surface have no significant impact on imaging. As long as you do not let the strong sunlight direct to the lens to cause the gray fog glare. But how can you tolerate the changing of your favorite camera lens into a big face? What should I do if it is not clean? Wipe it! Nowadays, lenses are usually coated with multiple layers. If you are not careful, the coating will be bruised and the lenses will be wiped. It causes irreparable losses to the camera. Are you sure you want to clean it? In my experience, the lens is always getting worse and worse, instead of getting better and better. Don't expect to restore the camera to a new look when it was just released. We recommend that you do not have to wipe the lens.   Prepare some tools before cleaning. Conventional weapons include lens water, lens paper (or wet lens paper), lens cloth (or suede), blow balloons, and skim cotton. Okay. Start now. First, blow the balloon to the dust, and then use the mirror paper to take care of it. Be careful not to use it. Take a little skim cotton, touch the mirror water, wet a little better, be careful to stick to the dust, stains still on the camera. This process cannot be hard, otherwise it is easy to damage the lens. A large area can be wiped when no visible dust particles exist on the surface. First, prepare a small cotton ball (with wet lens paper can also be) a number of, pressed over into a cake, the size of the mirror 1/3 is appropriate. Prepare large cotton balls and compress them into a pancake. The size should be 2/3 to 3/4 in the mirror. Try not to expose the cotton fiber to the working surface. Wipe the mirror with a small cotton ball and dry it well. Wipe the mirror with a spiral shape in the center. Do not go back. Then, when the lens water is not dry, use a large cotton ball to wipe the mirror in the same way. If the effect is not satisfactory, you can try again, but the used cotton balls should not be used again. Do not let the lens water directly touch the lens surface, you must use the lens paper, otherwise it may damage the lens coating or lens water along the lens edge infiltration into the lens, resulting in the Lens fog, or even degumming. What if there is no mirror water? It doesn't matter. You can replace it with an air on the lens surface. But Note: Do not throw your mouth when you are angry. You should open your mouth and breathe it gently, so that you will not spit it out. We only need to create a mist on the surface of the lens. If the lens is composed of plastic lenses, it is best not to use the lens water, nor to use alcohol and ether mixture to clean the lens, it is necessary to wipe the way to use. However, I think that, no matter how careful you wipe, there is always damage to the mirror coating, so there is no need to wipe the lens. The camera is used, not for reference.
