What should I do if the SLR zoom lens gets into the dust, and what should I do if the inside of the

First of all, it is necessary to make sure that the shadow does not affect the imaging, if it does not affect the energy, do not wipe it, because there is a layer of fluorite coating on the lens, and it is not good to wipe it well. If you really want to wipe it, you can determine the location of the ash, it may not be on the lens, maybe on the CCD, or on the mirror or viewfinder. If it's really just gray on the lens, take the lens off, twist the zoom ring to the maximum, blow it with an air blower and then wipe it back and forth with a lens cloth (be sure to use a special non-lint wiping cloth, otherwise it's better not to wipe it and don't use lens paper, that thing is too bad) and then blow it after wiping.

If it doesn't work, just take it to the store and let someone blow it with high-pressure air, it won't cost much. But beware of the staff fooling you, you go and say blow it with high-pressure air, and you don't have to do anything else. If the sand is not gray, it will be a big trouble, not to mention the impact on the image quality, not to mention the long-term Ruyi blocking the focus ring, once the zoom ring is broken, it is particularly expensive to repair it.

You'd better take it to a regular store and let someone handle it, and don't mess around. I suffered this loss, and when I came back from shooting in the desert, a shot was scrapped because there was too much sand. It's not really to scare you.

In fact, the structure of the external zoom and the external focus are easy to enter the dust, and the dust of the SLR lens is common, as long as it is not a lot, a small amount of dust has no effect on the imaging.

It's hard to take a zoom lens apart to remove dust, and it's a lot of money, and it can make the lens worse.

I think if you don't have the confidence and guts to take the shot apart. It is better to go to the repair point to clean the lens. Generally, the cost of dismantling and cleaning this kind of header is only 50 to 100 rooms.

As you said, the dust inside the lens is the dirt between the lenses, and this kind of disassembly and assembly requires a certain amount of professional data, and it is difficult to get the zoom error and the lens photosensitive film damaged; Moreover, the lens is placed randomly in the bag, which does not rule out the possibility that your lens has grown mold, which must be cleaned by a professional maintenance personnel with a special cleaning solution. If the mold is not cleaned up for a long time, then the whole shot is equivalent to a bill.

1. A small amount of dust does not affect the imaging, nor will it significantly affect the imaging quality, so there is no need to deal with it (some new lenses may have dust).

2. Some cameras are equipped with automatic dust removal, which can shake off the dust attached to the surface of the low-pass filter in front of the image sensor through ultrasonic vibration. When the camera is powered on or off, the sensor self-cleans. In addition, even if highly viscous dust cannot be removed by the sensor self-cleaning unit, the camera automatically records the location information of the dust removal data and removes the shadow caused by it with the random software Digital Photo Professional.

3. Serious ash can only be returned to the factory for treatment, and if you deal with it yourself, it may become more and more serious, which will cause lens scratches or assembly errors.

An extended lens is a structure that concentrates light so that the film can obtain a clear image. Early lenses consisted of monolithic convex lenses. Because of the poor clarity, chromatic aberration will be generated, and it is gradually improved into a compound lens, that is, the combination of multiple concave and convex lenses to correct various aberrations or chromatic aberrations, and through the lens coating (coating) treatment, increase the amount of light, reduce flare, so that the quality of the image is greatly improved.

Generally speaking, the lenses used in photography are focusing lenses, and according to the optical principle, after the light from a distance passes through the lens with a focusing effect, it will focus on one point, which is the focus. The distance from the focal point to the center point of the lens is called the focal length. On a camera, the center point of the lens is usually at the aperture, and the focus is on the focal plane (i.e., the film face).

Therefore, the focal length of the camera is the distance from the aperture to the film when the lens is in focus at infinity. The type of lens (categorized by application).

Wide-angle lens: the angle of view is more than 90 degrees, the observation range is large, and the near image is distorted.

Standard lens: The angle of view is about 30 degrees, and it has a wide range of use.

Telephoto lens: the angle of view is within 20 degrees, and the focal length can reach tens of millimeters or hundreds of millimeters.

Zoom lens: The focal length of the lens is continuously variable, and the focal length can be changed from wide angle to telephoto, and the longer the focal length, the greater the image.

Pinhole lenses: used for covert observation and are often installed in places such as ceilings or walls.

Hello Oh, dear I'm glad to answer for you If the inside of the camera is dusty, then it will be troublesome to clean up. When cleaning the inside of the camera, the camera must be turned on, and the environment in which the dust is handled requires that it be operated in a dust-free environment. The operation of turning on the camera is inherently technical.

5 5 It is recommended that if the inside of the mobile phone camera is dusty, you must go to the repair shop to repair it, but it is estimated that the repair shop will also recommend that you directly replace the camera to replace the dust removal operation, because turning on the camera is destructive, and it is difficult to meet the requirements of a dust-free environment.

1. First of all, make sure that the shadow does not affect the imaging, if it does not affect the energizer, do not rub it, because there is a layer of fluorite coating on the lens;

2. Determine the position of the ash when wiping, it may not be on the lens, on the CCD, or on the mirror or viewfinder window;

3. If it is only gray on the lens, take the lens down, twist the zoom ring to the maximum, blow it with an air blow and then wipe it back and forth with a lens cloth, use a special non-lint cleaning cloth, and blow it again after wiping;

4. If the sand is not ash, you need to take it to a regular store to let someone deal with it.
