There are a lot of white spots in the lens, and what is this white spot that appears in the lens of

Wow, that's a good shot.

Generally, it is mold, and it is more common for the lens to be moldy, but this lens is loose (far worse than a small bamboo cannon), and it may also be dust.

If you have a good handiwork, you can disassemble it yourself if you have tools at home, the first two lenses of this lens are very easy to disassemble, pay attention to find a box to put screws when dismantling, and put white paper on the workbench (no newspaper)!

If you're too lazy to do it or there are white spots on the inside of the whole shot, go to the pits, it will cost a little money, but be reliable.

The specific disassembly method is to find it on the Internet, there are many people who dismantle this lens, so be careful.

When scrubbing mold, use a medical absorbent cotton ball (be careful not to drop the cotton fibers into the mirror body!). Rub it with anhydrous alcohol (buy it at a chemical store) so that the alcohol will not leave traces after volatilization, and try not to use water.

It is best to store the lens in a drying oven or a box with desiccant (control the humidity, don't dry it too much, if it is too dry, the friction of many parts inside will be very strong, and the rubber parts will also age very quickly). But it's better to take it out and use it often, and often bask in the sun haha.

Note that the temperature of the sun is too high, more than 60 degrees will be a problem, and the black shell is relatively easy to reach this temperature in direct sunlight.

If the edges are hairy, silky, and immobilized, it is likely to be mold and should be dismantled and washed in time. Dust is generally moving.

It's over, and if it's moldy, it's a cost.

The friends upstairs are really experienced to learn about it.

It's hard to see from **. It looks like mold, but it also looks like something splashed on the lens coating and corrosion.

If something is splashed, you can wipe it with lens water on the surface of the lens.

When the lens is wet, mold will develop. Mold has a variety of shapes on the lens like patches, dendrites, etc. Lens mold, generally in the internal lens group between the lens, is difficult to clean, and the individual has no ability to clean up, because the lens assembly after cleaning is very strict, keeping the optical path coaxial, not biased or changing the distance, very small and precise, and needs to be tested and assembled by instruments.

Otherwise, the quality of the lens image will be affected.

Keeping the lens dry and the lens clean is the key to avoiding mold growth.

If it can be wiped off from the outside, it is a spot of water vapor.

It is not normal to have this white spot. Reason:

1.Unfixed dust, photoreceptor dust needs to be removed.

2.The defect of the photoreceptor is a quality problem, it is fixed on the photoreceptor, but when taking pictures, the focal length is changed, and the white point display is not fixed, so it does not affect the shooting. If it affects the screen, you can request a replacement.

Cause: If it is a white spot on the sensor, it is caused by missed detection during production.

Happy to you!

First of all, this must be abnormal, it is probably dust, my friend's invincible rabbit has a bug in it; Second, you can see the white dot from the viewfinder, which does not necessarily mean that the white dot is in the lens, or it may be in the viewfinder.

A small point will not affect the imaging, for example, the lens has tiny bubbles, and the manufacturer will not change it, because it will not affect the imaging.

It's generally a matter of lighting. The white dots on the eyes are the eye light, and the eye light is so that the eyes will not be dull. If the eye has a light-receiving side, it has only one eye light (the so-called white spot), and if there are two light-receiving sides, the eye will have two white spots.

And so on. Don't let the eyes get light, and the eyes won't have white spots. Or with ps.

The function of eye light: eye light is the light that causes the light spots on the eyes of the main character. It makes the character's gaze bright, bright and active.

Eye light is mainly effective in close-up and close-up scenes of the characters, but it is difficult to attract attention in large scenes. In addition, it is difficult to achieve the desired effect when the characters are walking back and forth or turning their heads frequently. The use of eye light in documentary programs can make people feel that the picture is artificially decorative.

The white spot is the eye light, and the general professional photography is to carefully arrange the eye light, and he must have the appropriate position and size in the eyes, so that the eyes look bright.

Most of the mold spots in the lens of digital cameras are caused by the lens being wet for a long time, which will affect the image quality of the camera, damage the lens coating, and even damage the mechanical structure of the lens. The specific methods of mildew removal and mildew prevention are:

1. If it grows on the outside of the lens, it can be cleaned with a special detergent;

2. If it grows in the lens, it may have to be cleaned by a professional master;

3. It is best to use a UV lens for protection and try to avoid the lens being drenched;

4. When the camera is not in use, it should be placed in a dry place to avoid moisture.

You don't know how you describe it, and I don't know what it is, but do you think it's like seeing through ground glass, or what? If it is simply similar to "seeing things through frosted glass", then there is no problem at all, there is a small thing called the focus screen in the SLR viewfinder (it used to be directly called frosted glass), it is not a smooth light-transmitting material itself, but like frosted glass, everything you see in the viewfinder will pass through its perspective, so [if it is a very uniform perspective similar to frosted glass], then your SLR has no problem at all.

Furthermore, when it comes to focusing screens above, there is a problem with the classification of focusing screens. Focusing screens are classified as purely physical, semi-physical, semi-electronic, and (almost all-electronic). Among them, the pure physical and semi-physical and semi-electronic focusing screens will be engraved on the ground glass with small dots that are easy to distinguish at the position of the focal point, but these engraved dots are easy to distinguish...But it's still up to you to give it a possibility – if the dense white dots you see from the viewfinder correspond to your camera's focus point, then that's fine....

If none of the above is the case, then it is likely that you have a problem with the fuselage, such as dust ingress. Rest assured, even if you wipe the lens with sandpaper, you will still not see anything like a "white spot" in the focusing screen, this is a depth of field problem, and the stains that can really be seen clearly from the viewfinder can only appear on the reflector, the focusing screen, the pentaprism, and the back of the glass on the viewfinder (the side inside the camera). In fact, if you don't actually see the problem you are talking about, then even the photographer who has been playing for a long time will not be able to tell what the problem you are talking about is.

So what's the easiest way?That is, you find a friend who has played SLR for a while, even if he has only played for a month or two, and let him tell you whether the camera is normal or not.

Ground glass in viewfinder, normal.

What model? Is it the focus?
