There are bubbles on the lens of a digital camera, how can there be bubbles in the lens of a video c

It feels like yours is not a bubble problem, it should be a noise phenomenon, generally shooting darker objects will appear noise, this is normal, no matter how good the camera is, noise will appear, but it can be controlled within a certain range, you can try to adjust the sensitivity, if the sensitivity is too high and it is a darker object, noise will appear, if it is really a problem with the lens, it can be seen from the appearance, if it is a CCD problem, then you put the photo into the computer** is not the blue dot you said, If this phenomenon is present on the camera, it means that there is a problem with the CCD. You can go to the merchant to exchange, but they seem to have to test, a bit troublesome, I hope it will help you. (It's best to find a blank piece of paper, then take a picture of it, and finally put it on the camera and computer**, and you'll know that there's a problem)

Judging from what you said "there is something similar to a bubble on the lens", it should be a problem with the quality of the lens, not a bad pixel of CCD, and if it is detected that there is indeed a problem with the quality of the lens, it should be able to be returned or replaced, which is the basic commitment of the three guarantees.

If it's a problem with the camera itself, it should be okay to ask for a refund within the time limit.

It is most likely to be a bubble, which has a great impact on imaging; Find a mall to return or exchange.

The weather is back to the tide, and the lens has mildew, so let's change it.

If it's not time yet, change it as soon as possible, don't study what's going on, and study it when it's done

Summary. Hello dear, glad to answer for you! The reason for the bubble in the current SLR lens is:

Something like a bubble is a bubble or dust inside the lens. This is because during the lens production process, if it is not completely cleaned or other human factors are generated, there will be some impurities such as bubbles or dust inside the lens. It could also be a "pseudo-bubble<> formed by the reflection of the light

What happened today when you suddenly found a bubble in a DSLR lens (which wasn't there before)? Hello dear, I'm glad to answer for you! The reason for the bubble in the first school of the current SLR lens is:

Something like a bubble is a bubble or dust inside the lens. This is due to the fact that during the lens production process, if it is not completely cleaned or other human factors are generated, there will be some impurities such as bubbles or dust inside the lens. It could also be a "pseudo-bubble<> formed by the reflection of the light

Extended information: SLR refers to single-lens reflex viewing, or SLR, in this system, the unique design of the He Qi reflector and prism allows the photographer to directly observe the image from the viewfinder to the image of Tongqin clapping his hand through the lens. A single-lens reflex lens mainly refers to a device that uses a single lens to reflex the framing and adjust the scenery to achieve optical imaging.

It means that the lens is very poor, and a good lens is free of bubbles.
