Cleaning strategy of SLR camera lens

The lens cleaning strategy for SLR cameras

Wiping tools:

1. Blowing balloons: Be sure to buy the one with a one-way air valve at the back and a one-way air valve at the front. Don't buy the cheap goods with one air inlet. It will be more difficult to clean the lens if dust is sucked in and sprayed.

2. lens paper: buy high-grade products as much as possible, the kind with long fibers, and it is best to buy a brand. The fibers of the lens paper with a different brand may fall off, and it will be annoying to clean it on the lens.

3. Absorbent cotton: It is available in pharmaceutical stores. Try to choose a large bag of 1 yuan with long and tidy fibers. It seems that the unloading cotton used by MM is of good quality, but we are not sure whether it is degreased, so don't use it indiscriminately.

4. Mirror cleaning cloth: Mirror cleaning cloth is a good tool found after recent research, which can be reused. If it is dirty, it can be washed with warm water and dried before use. Because the mirror cleaning cloth is a special fiber fabric, it does not shed hair crumbs, does not hurt the lens coating, and costs more than ten dollars. It can also be cut into two pieces for use. I suggest that when you buy mirror cleaning cloth for the first time, gently wash it with warm water and dry it before using it.

5. Lens pens: At present, there are only two kinds of lens pens on the market! One is carbon-headed, and the other is fluffy! Carbon-tipped pens are basically activated carbon technology products, which can effectively remove finger oil stains and general stains and dust, and belong to high-grade pens. The other is a pile pen. The pen tip of this pen is a piece of superfine fiber flannel, which is similar to the lens cloth, but made into a pen shape. Both of them are real pens, the more expensive ones with carbon heads are powerful, and the cheaper ones with pile heads are suitable for general dust removal and UV lens wiping.

6. lens cleaning solution: drop a small drop of lens cleaning solution on the wiping paper (be careful not to drop the cleaning solution directly on the lens), wipe the lens surface repeatedly with special cotton paper, and then wipe the lens with a clean cotton gauze until the lens is dry. If you don't have a special cleaning solution, you can breathe on the lens surface. Although the effect is not as good as the cleaning solution, it can also make the lens clean.

cleaning steps:

1. Blow with a blowing balloon

The correct method should be to first blow the dust off the lens surface with a blowing balloon (also called an ear washing ball). This kind of blowing balloon is sold in general photography shops, and the price ranges from several yuan to tens of yuan. However, care should be taken not to use a self-service compressed air tank as much as possible, because the pressure is too high, which may blow the dust into the gap of the lens, and do not directly.

2. Wipe the lens gently with a lens cleaning cloth/lens paper

If the dust on the lens surface cannot be cleaned by blowing balloons, we can also try to clean the lens with a soft brush, so that dirt and other dirty things can be taken out in general. For stubborn stains, such as finger marks, we need to use suede, lens cleaning cloth or lens paper together with lens cleaning solution to clean it. When scrubbing, be careful not to squeeze the lens surface hard, because the lens surface is covered with a fragile coating, which can be easily wiped off by hard cleaning.

When buying lens paper, you must go to a regular professional photography shop. Don't buy inferior lens paper just because it is cheap. When wiping the lens, never use hard paper, paper towels or napkins to clean the lens. Be sure to use cotton paper, and don't squeeze hard when scrubbing, because the lens surface is covered with a coating that is easy to be damaged. These products all contain scratching wood pulp, which will seriously damage the fragile coating on the camera lens. At that time, you may be? Too late to regret? Yes.

3. Wipe lightly with the lens pen

Before using the lens pen, be sure to blow off the lens surface and make sure that there are no dust particles. Then press the lens pen vertically and push it clockwise from the middle of the lens. After one time, pay attention to blowing off the lens toner that falls off the lens surface, and then observe the effect before wiping and blowing! Repeat 4-5 times and the lens should be as bright as new! Experts have said that any act of wiping the lens is harmful to the lens coating! Although the lens pen is a relatively safe tool, you should use it carefully. Always blow more and wipe less on the camera! Blower must be good, if necessary, with a better UV protection lens.

4. Use lens cleaning solution to remove stubborn stains (use with caution)

There are many arguments about whether to use lens cleaning solution, and some inferior brand-name cleaning solutions can really damage the lens, so we suggest that if you can clean stubborn stains on the lens simply by using tools such as suede, then you don't need to use cleaning solution, and you must pay attention to not using too much when you have to use it. And don't touch the cleaning solution outside the lens, because some cleaning solutions are composed of acetone, which can easily make the edge of the black lens fade, and in serious cases, it will deform around the lens, remember to remember!

If the lens is stained with oil or fingerprints, blowing or brushing is ineffective, you should gently wipe it with a very soft clean cotton swab (or mirror wiping paper) with a little lens water.

it is not recommended to use lens cleaning solution, which will wash off the coating if used frequently. On the other hand, the cleaning liquid will inevitably get dirty again when it is dried.

Some suggestions for cleaning the lens:

1. Never wipe the lens unless you have to

Start with a nasty fingerprint, wipe, wipe, but the lens always gets worse and worse, and there are not a few people who finally wipe the lens into a big face. We must remember that we only need to clean it when it is very necessary. In fact, fingerprints, dust and water stains on the lens surface have little effect on imaging, as long as we don't let strong sunlight shine directly on the lens.

2. Clean the lens for no more than 3 seconds

We suggest that it is best not to clean the lens for more than 3 seconds at a time, because wiping for a long time will also cause unnecessary damage to the lens, and if that happens, it will not be worth the loss.

3. Use a UV mirror or a hood to protect the lens.
