Lenses can be roughly dirty due to four factors,
There are always many small dust floating in the air. Since the camera has to get out of the air if you want to take a picture, then with so many tricks, you can not protect the lens from these dust. The slight amount of dust may not be seen in your eyes or even occasionally in the photo, but more dust can also damage your lens. These small dust can reduce the sharpness of your photo, and if there is a lot of dust inside the lens then there is also a problem in focus. To avoid these problems, first of all, you should filter the lens. Filters attach about 50 percent to the inside of the lens. And, of course, do not need to be in the camera when inserting the camera.
However, if the dust goes inside the lens for unnecessary reasons then you can use the lens cleaning toolkit. These toolkits in the market are available at different prices starting from 500. These toolkets usually have a microphone cloth, soft brush, cleaning gel, air blower and so on. First, remove the filter from the lens, then blur the dusts with the air blower. Most of the dust will fly, but some large dust still stays on the lens. In this case, clean the dust by rotating round the clock with microfiber cloth with Toolkit. If any oily substance is in the lens then apply a little cleaning gear to the cloth. The oil, the grid, the fingerprint darts will be easily accessible by this.
Like any other electronic device, the camera is very damaging to the lens. Most lenses have motor and electronic circuits that can be damaged by water or can cause malfunction very easily. So, in this case, what we have to do, first try to keep the lens away from the water as possible, unnecessarily free the camera lens in open weather. Use a quality waterproof casing or bag if you want to take pictures in the rain. After taking photos, keep the lens covered with a dry towel. Eventually, if the water inside the lens is inserted, take a silicone gel in an air-tight box and keep the lens in it as if there is silica gel around it. If you do not have silica gel, keep the lens in a cotton cloth and keep it in the drum at least 10 hours. In this way the rice will absorb the water slowly inside the lens. However, if you think the lens is water then contact the experts.
Fungus is a big problem for any lens. Wet weather is mainly responsible for growing fungus in lenses. If the fungus are very small, it does not cause any harm, but if there is continuous humid climate then they spread and spread throughout the lens. It is a time to see that they are very influential in your film. If you want to protect the lens from the fungus, keep the lens dry and cold. In the airtide boxes available in market, the silica gel should be filled in the lens. If the fungus is seen in a small amount, then keep the lens in front of the hard sun and keep it for at least 3 hours, so that the sun's ultraviolet rays will die in the fungus and will not be able to reproduce. But if for some reason the fungus is grown but there is no other way than to open the lens. In this case, experts will have to go.
For various reasons the lens may stain. There are some spots that are made due to oily or hand print, these stains can be easily removed with lens cleanser gel. But there are some hard spots that can not be carried away by anything. So do not forget that we do not have to do the work. Lens filter protects lenses from dust like dust and protects from the scars. Therefore, always use filter to avoid scratches in lenses.
