What should I do if the Z72 eyepiece cover is very sticky?

The specific methods are as follows:

Wiping tools:

1. Blowing balloon: Be sure to buy one with a one-way air valve for air inlet at the back and air outlet at the front. Buy a cheap one that has one outlet for the air and one for the air in. If dust is sucked in and then sprayed onto the lens, it will be more difficult to clean. The blowing ball is a kind of dust-removing blowing ball with a special design. Because it has added support for the back of the hand, there is no fear of it falling from the hand.

2. Lens paper: Try to buy high-end products, long-fiber ones, preferably of a well-known brand. The fibers of miscellaneous brand lens paper may fall off, and it will cause trouble to clean if it sticks to the lens. Very annoying. Lens cleaning paper, which is common in China, is high-quality and low-priced, but has very hairy ends. This is because the fiber of the lens paper is soft and long, and will be stretched when it is torn.

3. Absorbent cotton: Available in medical stores. Try to choose one with longer and neater fibers. A pack costs 1 yuan. It seems that the removal cotton used by girls is of good quality, but I am not sure whether it is degreasing, so don't use it indiscriminately.

4. Lens cleaning cloth: Lens cleaning cloth is a good tool discovered after recent research. It can be used repeatedly. If it is dirty, it can be washed with warm water and dried before use. Because the lens cleaning cloth is a special fiber fabric, it does not remove lint and does not damage the lens coating. It costs more than ten yuan, and you can cut it into two pieces for use. It is recommended that when you buy a lens cleaning cloth for the first time, gently wash it with warm water and let it dry before using it. 3M Magic Cloth has passed the non-scratch test and has excellent lens cleaning effect without leaving any lint.

5. Lens pen: There are currently only two kinds of lens pens on the market! One is a carbon-headed one, and the other is a velvet-headed one! The carbon-headed pen is basically an activated carbon technology product, which can effectively It is a high-end pen that can remove oil stains from fingers and general stains and dust. The other type is a velvet-tipped pen. The pen tip of this pen is a piece of microfiber velvet cloth. The principle is similar to that of lens cloth, but it is made into a pen shape. Both are real pens. The one with the carbon head is more expensive and has more functions, while the one with the velvet head is cheaper and suitable for general dust removal and wiping UV lenses. Lens pen.

6. Lens cleaning fluid: Put a small drop of lens cleaning fluid on the wiping paper (be careful not to drop the cleaning fluid directly on the lens), and wipe the lens surface repeatedly with special tissue paper, and then clean it with a Use cotton gauze to clean the lens until it is dry. If you don’t have a special cleaning fluid, you can breathe on the surface of the lens. Although the effect is not as good as cleaning fluid, it can still make the lens clean. Note: There is a coating on the surface of the lens. Frequent use of cleaning fluid will wash away the coating and affect the optical imaging effect. Put a small drop of lens cleaning fluid on the wiping paper. Be careful not to drop the cleaning fluid directly on the lens.

Cleaning steps

1. Blow with a blower

The correct method should be to first blow out the surface of the lens with a blower (also called an ear cleaning ball) Dust, this type of blower is sold in general photography stores, and the price ranges from a few yuan to dozens of yuan. However, be careful not to use self-service compressed air tanks, because the pressure is too high, and dust may be blown in. Do not blow directly with your mouth into the gaps in the lens. Otherwise, a lot of saliva particles will blow onto the surface of the lens, which will make it more difficult to deal with. Use an ear blower to blow off the fine dust on the lens.

2. Wipe gently with lens cleaning cloth/lens paper

If the dust on the surface of the lens cannot be cleaned with a blower, we can also try to use a soft brush to clean the lens. Generally speaking, You can remove dust and other dirt. For stubborn stains, such as fingerprints, we have to use suede, lens cleaning cloth or lens paper combined with lens cleaning fluid to clean. When scrubbing, be careful not to squeeze the lens surface too hard, as the lens surface is covered with a fragile coating that can easily be wiped off by vigorous cleaning. Rotate the cylindrical bristle end outward from the center of the lens and sweep it gently to remove impurities on the lens.

When purchasing lens paper, be sure to buy it from a regular professional photography store. Do not buy low-quality lens paper just for the sake of cheapness. When wiping the lens, never use hard paper, paper towels or napkins to clean the lens. Be sure to use tissue paper, and do not squeeze hard when scrubbing, because the surface of the lens is covered with a layer of coating that is relatively easy to damage. These products contain scratchy wood pulp, which can seriously damage the delicate coating on the camera lens, and you may regret it by then.

3. Wipe lightly with a lens pen

Be sure to blow off the lens surface before using the lens pen to ensure that there are no dust particles, and then press the lens pen vertically and clockwise from the center of the lens Rush outward, and after one time, pay attention to blow off the lens toner that has fallen off the surface of the lens, then observe the effect, wipe and blow again! Repeat 4-5 times and the lens should be as bright as new! Experts say that any behavior of wiping the lens is harmful. The lens is coated! Although the lens pen is a relatively safe tool, you should use it with caution. Always blow more and wipe less on the lens! The blower must be good, and if necessary, the lens must be equipped with better UV protection. Use a lens pen to wipe lightly. It should be noted that the lens pen also has a lifespan. When the bristles are smoothed, they must be replaced.

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

There is a lot of debate about whether to use lens cleaning fluid to clean the lens. Some inferior brand-name cleaning fluids will indeed damage the lens. Cause damage, so we recommend that if you can simply use suede and other tools to clean away stubborn stains on the lens, then you don’t need to use cleaning fluid. When using it as a last resort, you must be careful not to use too much, and don’t get the cleaning fluid on it. To places outside the lens, because some cleaning fluids contain acetone, which can easily discolor the edges of the black lens. In severe cases, it can also cause deformation around the lens. Remember! If the lens is stained with oil or fingerprints, blowing or brushing will not work. Just use a very soft clean cotton swab (or lens tissue) dipped in a little lens water and wipe it gently.

It is not recommended to use lens cleaning fluid. Frequent use of cleaning fluid will wash away the coating. On the other hand, cleaning fluid will inevitably pick up dirt again as it dries.

Some advice on cleaning the lens:

1. Never wipe the lens unless absolutely necessary

Start with a nasty fingerprint, wipe, wipe, wipe, However, the lens always gets worse as it gets scratched, and there are not a few people who end up with the lens scratched into a painted face. We must remember to only clean it when it is extremely necessary. In fact, fingerprints, dust, and water stains on the surface of the lens do not have much impact on the image, as long as strong sunlight is not exposed to the lens. I wiped it left and right, and it was too late when I found that the lens coating was worn away and the mirror surface was scratched.

2. Clean the lens for no more than 30 seconds.

We recommend that the cleaning time of the lens should not exceed 30 seconds each time, because wiping the lens for too long will also cause unnecessary damage to the lens. Damage, if that's the case, it's not worth the gain. Do not wipe the lens for a long time.

3. Use UV mirror or hood to protect the lens

We should pay attention to the daily maintenance of the digital camera lens, such as when using it in a windy and sandy environment, after the shooting is completed After that, put the machine into the camera bag immediately. When not in use, cover the lens cover or install a UV filter to protect the lens. During the shooting process, be careful not to leave fingerprints on the lens with your fingers.
