When fog appears inside the lens, it is caused by moisture entering the lens and condensing. Foggy lenses can be placed in a dry and ventilated environment to avoid further accumulation of moisture. A desiccant (such as silica gel) can be placed in a closed container and stored with the lens to absorb water.
You can also place the atomized lens in an environment with low relative humidity, and the atomized lens may naturally evaporate over time. This may take a while, depending on the humidity. If the natural evaporation fails, the lens can be sent to a professional camera maintenance center for processing. Maintenance personnel will remove the lens, clean up the moisture inside, and ensure that the lens works normally.
Lens protection method
1, use the ultraviolet filter: the ultraviolet filter is a transparent filter that can prevent ultraviolet rays from entering the lens and protect the lens. It can also improve the contrast and color saturation, without affecting the photo quality and protecting the lens from damage.
2. Note: When replacing or cleaning the lens, handle the lens carefully to avoid forcibly bumping or scraping the lens. It is recommended to wash your hands before replacing the lens to ensure that the lens holder is in a safe position.
3. Use the lens protective cover: The lens protective cover is a specially designed cover that can be placed in front of the lens to protect the lens from dust, fingerprints, water droplets, etc. When not shooting, try to protect the lens with a protective cover.
