Daily maintenance of SLR lens

Daily maintenance of SLR lens The lens is the camera's eye, directly determines the quality of the image. The expensive part of SLR is reflected in the lens, so we must pay attention to the protection of the lens during the daily use, as well as the maintenance of the lens when placed. The lens may be broken, mildewed, scratched, etc. Careful use and care must be taken. The following small series describes the daily lens maintenance steps.

(1) Proper use. The glass device is easily broken, and the lens must be prevented from being bumped when used. Avoid strong sunlight for a long period of time to prevent the lens from being heated, causing the glued lens to open and affect the transparency.

(2) Anti-fouling and moisture-proof. When using the lens, do not touch the lens with your hands because the perspiration on your hands is acidic and can erode the mirror. The lens has been contaminated with dirt, hard handkerchiefs and other objects. Use audition paper, special brushes, balloons, wipe or blow. The lens surface of the lens is extremely prone to mildew, resulting in moldy spots like spider webs, making the lens worse. To avoid lens mold, must be moisture-proof, waterproof. Be sure to wipe dry after use. When the lens is not in use, place it in a sealed bag or a sealed box with a desiccant.

(3) Clean the lens. The lens is not clean, it will affect the picture clarity. Therefore, it is very important to keep the lens clean. There are three ways to do it.

First, when the lens is contaminated with dust, use a special balloon to blow off the dust that sticks to the lens. If you can't blow away, brush it with a lens brush first, then use balloons to blow loose dust.

The second is that when the camera has oil stains and fingerprints, you can use a cotton ball with a little lens cleaning solution or absolute alcohol, from the lens center to the edge of the gradual rotation wipe. Replace the cotton ball every time you rub it, so that you can wipe off oil stains and fingerprints several times.

Third, when there are mildew on the lens, you can use a 20% anhydrous alcohol and 80% ethyl ether mixture on the absorbent cotton balls to carefully wipe the mildew spots, and for the less serious mildew spots, you can wipe them off.
