How to clean the camera lens?

Question 1: How to clean the lens of Canon digital camera, common cleaning tools, usage, advantages and disadvantages;

1. lens paper, lens cloth and deerskin;

This kind of electric appliance is often chosen by ordinary consumers because of its low price, but its cleaning effect and safety are not satisfactory. Once the package is unpacked, a lot of dust particles are easily attached to the surface (to be honest, I don't believe they are dust-free without unpacking). If you use this dirty paper and cloth to wipe the lens, it is equivalent to polishing it with sandpaper, which is very easy to scratch the lens.

The correct usage of lens paper is to roll it into a tube, gently brush off the dust on the lens surface and absorb the liquid such as raindrops. The quality of lens paper is the most difficult to control, often only a few cents, not much better than napkins. Not if it works.

Lens cloth is mainly used to wipe the camera body and accessories, remove dust and stains, and stick liquids such as raindrops to the lens. Lens cloth is easy to shed some fibers, and it is easy to cause secondary pollution when used to wipe the lens.

Deerskin and lens cloth have similar characteristics. In addition, it is easy to harden and needs to be replaced frequently.

2. Blow and brush;

Blowing, also called leather blowing, can blow off the dust on the lens surface. When using, pay attention to that the nozzle forms a certain angle with the lens surface, and do not touch the lens. Inferior cowhide is easy to age, and rubber particles will fall off from the inner wall and be ejected by compressed air, which is self-evident for the lens. Advanced blower, air inlet and air outlet are different channels, which is safer. Just a reminder, don't blow the camera with your mouth, it will definitely splash! Remember not to forget! ! !

Brushes are also used to remove dust, mainly to deal with die-hards who can't blow them off. The texture of the brush should be soft, so as not to lose dander. When in use, the lens should be tilted to facilitate the escape of dust.

3. lens pen;

Better cleaning tools. One end is a brush, and the other end is a soft pen with a special cleaning mixture. Sweep off the dust with a brush first, and then wipe off the oil stains, handprints, etc. with a pen. It is important to note that wiping should always follow a spiral trajectory, step by step in the direction of rotation from the center to the periphery, and must not be rubbed back and forth. After using the pen, cover the pen cap in time, rotate the pen cap and replenish the cleaning liquid (commonly known as toner) for the next use.

4. Lens cleaning solution;

This kind of cleaning products belong to the "professional" level, with complicated operation and no serious pollution, and are generally not used. I haven't used it either, so I won't comment.

Generally speaking, high-end cameras need the following cleaning supplies:

Lens cloth+leather blowing+lens pen. The lens cloth wipes the fuselage, and the leather is blown to remove dust. The brush of the lens pen removes dust that cannot be blown off, and the nib of the lens pen erases oil stains and fingerprints. When you encounter a stain that has been dried, you can take a few breaths, moisten and soften it, and then wipe it.

About chemical solvents such as alcohol.

Generally speaking, it is not recommended to use chemical solvents to clean lenses. General medical alcohol can't be used, because the concentration is only 75% or 95%. Must use, also want to use anhydrous ethanol, anhydrous ethanol and chemical purity, analytical purity, in short, the more pure the better. I have also seen people say that the specific effect and safety of ethanol mixed with other chemical solvents are unknown.

About the cleaning frequency.

Try to reduce the number of cleaning, even the best cleaning equipment will wear the lens. Generally speaking, there are a few grains of dust on the lens, which does not affect the imaging; One more fingerprint, the impact will not be unacceptable, so don't be too "neat", clean is enough, almost enough.

The lens is the eyes of the camera, and we really should love her as much as our own eyes. Use cleaning products correctly to avoid accidental injuries, and at the same time, it is best to match a UV mirror for protection. After all, a UV mirror is only a few tens of dollars, and you can change it after you spend it.

Question 2: How to clean the lens? First of all, never wipe the lens unless you have to. In fact, fingerprints, dust and water stains on the lens surface have little effect on imaging. As long as you don't let the strong sunlight shine directly on the camera. I think many netizens in the jar started with a dirty fingerprint, rubbed and rubbed, and finally rubbed the camera into a big face. I can't help it, because I love cameras too much. I am an example. My experience is that the lens is always getting worse, not better. Don't expect to restore the camera to its original state. Anyway, if you have to clean the lens, I hope my experience and lessons can help.

I don't like to use lens covers, so each of my lenses is at least protected by UV mirrors. After all, there are only more than 100 pieces of things, even if they are scratched, they will not be too distressed. Every time I go out and come back, my ultraviolet rays are terrible, including fingerprints, dust, water stains, oil stains and spit. . . . . . . So I wiped it.

I have used several kinds of lens water:

The lens water in the three-piece cleaning suit on the market: this thing is purely deceptive, a brush, some lens paper and a bottle of liquid with unknown composition (look for it, it is tasteless and nonvolatile, probably just pure water). A few dollars can buy dozens of things. I bought two or three different brands, and now I only use cotton to wipe the sweat stains on the fuselage. It is recommended not to buy it.

HAMA lens water from Germany: HAMA accessories are quite famous, but this lens water. . . . . . But maybe that's my opinion. 15 ml, unknown composition (Germany), highly volatile, slightly greasy on fingers, about 50 RMB. This thing is real, but I can't always use it well. After wiping, there will always be many traces on the lens, probably because it contains too many cleaning ingredients.

Kodak lens water: The main components are water and ammonia, around 80 yuan. More volatile, no greasy feeling. I think the cleaning effect on oil stains is still good. But when it's dry, it will leave some marks. I usually use it to clean stains on the surface.

Anhydrous ethanol: bought a large bottle of analytical pure, 10 RMB. I think it would be better if there were something purer. I usually use it for final treatment.

Please refer to: xianpp/? The content is too long for me to copy.

Question 3: How to clean the lens of a digital camera? Sorry, you can't. Glasses cloth is not allowed.

You can only use a special lens to wipe the paper (a small book, paper torn one by one, 2 yuan one. But this is still low-level and not recommended. ), absorbent cotton, special lens pens (more than ten pieces, more than twenty pieces) and other professional auxiliary tools. Note: Before wiping, visible and invisible dust and impurities must be blown off with a blowing ball.

Again, a little dust won't affect the picture quality, so it's not necessary to wipe the lens easily.

Go to your local photographic material store; Online, as well as online physical stores can be purchased. See more, learn more, shop around, and the price is more favorable ...

Note: the words of Coke Sprite Sunkist upstairs need reference. It's best not to try easily. First of all, you should blow the balloon, not blow it when you see ash. Secondly, I haven't heard that the lens is directly dipped in water. No matter what water it is, the lens is afraid of getting wet and should be avoided. Can you dry it thoroughly after use? -this is a common sense question; Finally, the lens paper currently available on the market is not so good. More personal practical experience, it is not recommended to use, let alone non-woven fabrics. Not to mention whether it is competent or not, can it ensure that every link of this cloth is dust-free from production, transportation and arrival at your home? Your wiping technique is correct, that is, gently wipe the lens with spiral concentric circles from the center of the lens.

Finally, it is recommended to purchase and install an ultraviolet filter. The hood is also a complete set.

Question 4: How to clean the lens of SLR camera? Kuba helps the little assistant to answer your questions about "". Everyone may be concerned about the shooting skills of the camera, but have you ever cared about the maintenance of the camera? In fact, keeping a camera is as learned as buying a camera. Proper equipment and reasonable storage of cameras can prolong the service life and ensure high-quality output. Below Kuba helps a little helper to teach you how to maintain the lens of a SLR camera. Common cleaning appliances, usage, advantages and disadvantages: 1. Lens paper and lens cloth; This kind of electric appliance is often chosen by ordinary consumers because of its low price, but its cleaning effect and safety are not satisfactory. Once the inferior lens paper is unpacked, a large number of dust particles are easily attached to the surface. If you use this dirty lens paper and lens cloth to wipe the lens, it is equivalent to polishing it with sandpaper, which is very easy to scratch the lens. Fortunately, there are two kinds of things on the market now called ultra-micro non-woven lens paper and ultra-micro fiber lens cloth. This kind of paper and cloth is made by a unique process, which can ensure absolute dust-free and avoid secondary pollution when cleaning the camera. Correct use of microfiber lens paper and microfiber lens cloth Reminder: It is best not to use lens pen when cleaning camera lens, because the principle of lens pen is "adsorption" and dust will accumulate in the lens pen part. After a long time, the lens will not only be wiped clean, but will become more and more dirty, causing secondary pollution. 2. Blow and brush; Blowing air can blow off the dust on the lens surface, which is an unnecessary cleaning tool in the first step of cleaning the camera. When using, pay attention to that the nozzle forms a certain angle with the lens surface, and do not touch the lens. It goes without saying that inferior air blows easily and rubber particles will fall off from the inner wall and be sprayed out with compressed air. High-quality hair dryer, air inlet and air outlet are designed separately, which is safer. Just a reminder, don't blow the camera with your mouth, it will definitely splash! Remember not to forget! High-quality compact hair dryer High-quality professional hair dryer brushes are also used for dust removal, mainly to deal with those diehard fans who can't blow out. The texture of the brush should be soft, so as not to lose dander. When in use, the lens should be tilted to facilitate the escape of dust. Thin and soft brush 3. Lens cleaning solution; Lens cleaning liquid is generally used to remove stubborn stains such as handprints and oil stains. Pay attention to control the dosage when using, and don't use too much to avoid cleaning. It is best to choose a lens cleaning solution with good volatilization effect, and then use it with superfine non-woven lens paper or superfine fiber lens cloth, and the effect will be better. Generally speaking, a high-end camera needs the following cleaning supplies: hair dryer+lens cloth/lens paper+lens cleaning liquid. The lens cloth is used to wipe the fuselage and lens. The first step is to remove dust by blowing, and the lens cleaning solution is used to wipe oil stains, fingerprints or air-dried stains. About the harm of chemical solvents such as alcohol to the camera: Generally speaking, it is not recommended to use chemical solvents to clean the lens. General medical alcohol can't be used, because the concentration is only 75% or 95%. Anhydrous ethanol will dissolve the surface coating and fixing materials of camera lens or sensor to a certain extent, and accelerate the aging, so it is very discouraged to use chemical solvents to clean the camera. About the frequency of cleaning: the cleaning and maintenance of the camera is an important part of daily maintenance, and of course it also depends on the dirty degree of the camera. Generally speaking, there are a few grains of dust on the lens, which can be easily solved by blowing; One more fingerprint, you can use lens paper or lens cloth. The lens is the eye of the camera, and we should really care for it as much as we care for our eyes. Correct use of high-quality professional camera cleaning and maintenance supplies to avoid accidental injury, it is best to match a UV mirror for protection.

Question 5: The SLR lens is dirty, how to clean it? 1. lens cleaning:

Fingerprints and dust on the lens will reduce the performance of the camera. It is best to wear anti-ultraviolet glasses when buying, and there must be a certain method to wipe the lens, otherwise it is easy to scratch the lens.

Method 1:

When cleaning lenses, we choose the following tools: professional mirror cleaning cloth/suede (never glasses cloth), professional lens paper, soft brush, balloon blowing, mirror cleaning water, etc. (These can be bought in professional equipment stores.)

If there is dust, blow it off with a balloon first. If you can't blow it off, you can sweep it with a brush. Remember not to touch the soft brush with your hand, because there is oil in your hand. Then, the mirror cleaning liquid drops are wiped on the mirror cleaning cloth from the inside out. Pay attention to several times, and don't push too hard at a time. Then use a balloon to blow off the remaining dust.

Method 2:

For example, in the case of insufficient equipment, we only have mirror cloth or mirror paper.

Then the way to blow the lens is to hold your hand in front of the lens at an angle of 30~45 degrees, and blow into your hand with your mouth. The air will reflect on the lens and blow away the dust. This has the advantage of preventing saliva from blowing on the lens.

Method of cleaning lens: Breathe into the lens (equivalent to the role of mirror cleaning liquid) to prevent dust from scratching the lens, then wipe the lens with mirror cleaning cloth or mirror cleaning paper, and spin out the wiping method from the inside out.

The combination of the above two simple methods can clean the lens in an emergency, and the first method must be followed at ordinary times.

2. Some preventive measures

After use on the beach or near chemicals, thoroughly clean the lens and fuselage.

If the camera breaks down, don't disassemble it by yourself under any circumstances, but send it to the maintenance department for repair.

Do not use solvent benzene, pesticides and other volatile substances on the camera to avoid camera deformation or even dissolution.

Don't put the digital camera in a closed car in the sun. High temperature will not only deform the plastic shell, but also shorten the service life of digital cameras.

3. On the LCD screen

The most common thing is that there will be fingerprints of fingers or some oil and dust, which looks disgraceful. Generally, it can be wiped with a detailed glasses cloth. Remember to wipe gently and be careful not to use strong glass cleaner, because some digital cameras have an anti-glare film on the LCD surface. Once the film is damaged, it can't be repaired, which is not covered by the warranty. In addition, you can also buy and use a screen protector. Just take it back and cut it into a suitable size and stick it on the LCD screen to prevent the LCD screen from being scratched.

But now most digital cameras have improved the LCD, and the outer layer is a layer of glass, so you don't have to pay too much attention to adding screen protection stickers on the LCD, so it looks clearer. Don't let these stickers stop obstacles and make shooting interesting.

Question 6: How to clean the dust of camera lens? It's best not to wipe the lens with anything. If it doesn't affect the photo quality, it's best not to touch it, because there is a coating on the lens and there are black spots when taking pictures. Buy a lens paper or blow a balloon to remove dust, but don't use it often. It's really unbearable to use Buy a better bag to maintain the camera. Preferably waterproof.

Question 7: How to clean the camera lens and what should I do if the camera is dirty? Regarding the cleaning of the camera lens, the stains on the lens shell can be wiped, and the dust on the lens surface can be removed.

But once the inside of the lens is dirty, individuals can't handle it at all. I can only take it to the professional after-sales department for handling.

Question 8: How to clean the inside of the camera lens? It seems to be frosting. Can only be opened.

It is recommended to go to Canon's after-sales service center. It takes about a few days to a week, and the cost is above 100.

Question 9: How to clean the dirty lens of SLR camera? First of all, it is imperative to ensure that shadows do not affect imaging. If not, don't wipe it, because there is a fluorite coating on the lens, which can't be wiped well. If you really want to wipe it, you can determine the position of the ash, which may not be on the lens, may be on the CCD, or may be on the reflector or viewfinder. If it's really just the dust on the lens, then take off the lens, screw the zoom ring to the maximum, blow it with air, and then wipe it with a mirror cloth (be sure to use a special cloth that won't lose hair, otherwise it's better not to use lens paper, it's too bad) and blow it again. If not, take it to the store and let people blow it with high-pressure air at home. It won't cost much. But beware of the staff fooling you. When you go, just blow it with high-pressure air and do nothing else. If the sand is not ash, it will be in big trouble. After a long time, it will affect the image quality and block the focus ring. Once the zoom ring is broken, it will be particularly expensive to repair. You'd better take it to a regular store and let someone else handle it. Don't mess around. I have suffered this kind of loss. I came back from filming in the desert, and one shot was scrapped because of too much sand. I really didn't scare you.

Problem 10: The lens of the card camera is dirty. How to clean it? First of all, blow

The dust on the lens is best blown clean, not wiped. Because the coating on the surface of many lenses is very delicate, small dust particles will be scattered on the lens surface. If we wipe the lens paper directly, the dust will act as sand on the sandpaper between the paper and the lens film surface, which will easily damage the delicate film surface, especially for the plastic lens of low-end consumer machines. So the correct way is to use a special blower, which is also available in medical equipment stores. The scientific name is ear washing ball. Or go to the photographic equipment city to buy it. It looks a lot, but there are some plastic blowers in the photographic equipment city, which are not very strong. Rubber is very good. Just hold them in the palm of your hand and blow them into the camera.

Second, wipe

Blow off the dust before wiping. Generally, watermarks and stains should be cleaned as soon as possible. For example, saliva or acid-base rain stains slightly erode the membrane, which may damage the membrane surface after a long time. The cleaning method is to take a breath at the lens and wipe it on the lens surface with lens paper clockwise or counterclockwise. Do not store and rub back and forth. The main points of wiping are: light in, slightly heavy wiping, and then light up as a process, and after wiping a process, the paper must be wiped again. Suede is a good lens wiper, but the quality of artificial suede is different, so don't use it well. If some parts of natural suede become hard, don't use it again, which will easily scratch the lens. At present, the lenses of consumer DC are very small and can not always be wiped with lens paper or suede. It is recommended to use a special lens pen with a brush at one end to brush off large dust. The other end is a self-lubricating suede head, which is small in area, but it works well. It can be well used to wipe off the traces on the small lens, while the traces on the large lens do not need to be wiped on a large area. The only drawback is that the price is expensive, and the cheap price is around 50 yuan, and the good price is around 200 yuan.

Third, wash

If the surface of the lens has a large stain, or the trace remains for a long time, or it is sticky, and simple wiping can't solve the problem, then it is necessary to simply clean the lens. The cleaning method is simple. Find a medical cotton swab, that is, an absorbent cotton ball. There must be a thick cotton ball at one end of the stick to prevent the cotton ball from being too thin and the stick from scratching the lens surface. Dip a cotton ball in a little pure water and squeeze out the water, that is, scrub the stains in one direction for many times in a wet state, dry them with a hair dryer after the stains are removed, and then clean them with lens paper in the way of 2. If you can only wipe with water, don't use alcohol or other cleaning liquid.

Fourth, protection

The above three methods are passive lens protection, and the most effective lens protection is to install a UV mirror for DC, because a UV mirror costs only tens of dollars, forming a relatively closed environment between the UV mirror and the lens surface, which can effectively isolate dust. The above methods can also be used to clean the UV mirror, even if it is damaged, you don't have to feel bad.

Five, dry

Whether it is the DC lens or the electronic part of the fuselage, it is necessary to exclude the humid environment. Therefore, after shooting in rainy days, or after wet washing the lens, it is recommended to dry it and put it in a drying oven. In fact, we made a drying oven ourselves. We can buy a plastic storage box with good sealing and moderate size in the supermarket, collect a little desiccant (in many electronic equipment packages or some small food packages) and put it in the box.
