Canon 70 200 2 8is II rear lens wiped with a cleaning cloth, what are the consequences? Please teach

For lenses, no matter which lens, there is a very delicate coating, generally speaking, try not to use the "wipe" way to deal with it. If it is dust, it can be removed by blowing or brushing and blowing. If you encounter a stubborn stain, try not to deal with it if it is small enough to affect the image.

Because no matter what you use to wipe it, it will always destroy or damage the coating.

If you have to do so, be sure to wipe it off, make sure to blow off the dust before choosing professional lens paper or cleaning water to clean it.

For your current situation, if it is clean, or it does not affect the imaging at all, don't touch it again, the less rubbing the better, not wiping the best.

As for the current condition of the lenses, I don't know what kind of cleaning cloth you used to treat them, and how you handled them, so I can't tell. But I believe you are a person who cherishes the camera, and you won't be too rough, right? As long as you don't have any excessive movements, it should not have much impact, normal minor damage, and the worst result is only a small partial decoating, but you can still use it with confidence!

If I were you, I wouldn't wipe it, just blow it with an air blow. If you really want to wipe, blow it with an air blow first, then dip a cotton swab in water, wet the lens, and then wipe it with lens paper in one direction, don't use too much force. If you're really distressed, go buy lens fluid.

It's okay, don't worry. Canon's rear lenses have a protective coating, and cleaning cloths are very low. Please feel free to use it!

l head, the sealing is very good, I don't know if the landlord's dust is in **?

If it is in the lens tube, the main consideration of the building is whether it has fallen? If you buy parallel goods or refurbishment, be cautious!

If it's dust outside the mirror, that's how I usually deal with it:

1. Use a small brush to flick off the tiny particles of dust.

2. Use lens paper (if you don't have one, use a paper towel), fold several layers in half, and pull it away from the middle.

3. Take a sigh on the mirror, use the side of the hair that is pulled apart, start from the middle of the mirror, and wipe in a circle.

There should be no dust in the lens of this lens, because the sealing of this lens is very good. If it is on the outermost lens, you can use a very soft glasses cloth and air blow to clean, if it is the position of the bayonet, there is dust in the cotton part of the bayonet, you can carefully glue it off with transparent glue. If it's inside the lens, it's recommended not to clean it yourself, where to go to Canon's after-sales service to clean it, if it's within the warranty period, you can clean it for free, if it exceeds the warranty period, you have to pay for it yourself, It seems to remember that ** is also a hundred dollars.

If there is ash on the mirror surface, you can use an air blow or a lens pen to clean it. Don't disassemble the ash inside, take it to a professional after-sales cleanup, thank you.

The small particles of dust inside the lens will not be imaged on the negative, so it will not affect the image quality.

But if you have a lot of dust, it will happen, so be careful.

If you just bought it and don't know how to get ash, you need to confirm the reason for the ash (there are also cases where the inner wall coating falls off, so you need to change the lens).

The phenomenon is normal, and your method is very abnormal. The sound is the sound of the ceramic ball in the anti-collision box in the image stabilizer system. The lens is a high-precision instrument, and your method can only exacerbate the early obsolescence of the lens.

Normal, some of them are the movement of the anti-shake component, which is completely fine, but if it shakes, it will break, and the lens cannot be transported and used.

Hello, this should not be a problem once or twice, it is difficult to say if you wipe too much, it is recommended that you buy a professional cleaning kit.

We hope you are satisfied.

1. All are not bad money, or try to buy licensed goods.

Check the front and back seals. Whether there is dust in the lenses.

Test whether it is out of focus on the machine.

If it's no problem, just pay the money and leave.

What's the problem? Why don't you just ask the question?

1. Focus distance selection.

2. Autofocus and manual focus selection.

3. Anti-shake switch.

4. Up-and-down anti-shake and horizontal anti-shake (generally put it at the position of 1, and put it at 2 when capturing horizontally moving objects).

It can only be said that it is very good, there is nothing else to say, what is better than him is the fixed focus.

Very good. The famous red-circled telephoto lens.

The domestic Jumeiv and German Schott glass have an ultra-thin double-sided eighteen-layer film, or a green film, and the quality is very good, which is available on Jingdong.com.

You can use the B W 77mm XS PRO MRC UV mirror, which is cost-effective.

It's a white rabbit.,You can configure a better UV.。

Of course, you can also configure the original 77mm protective mirror, which is about 430 yuan.

Others can consider B+W, Zeiss, Baogu, Kengao; There are a lot of fakes in the last two brands, so pay attention to screening when buying.

It is equipped with Kenkel ultra-thin multi-film UV mirrors.
