The key steps and precautions for lens maintenance and care include the following:
Clean the lens: After shooting, remember to protect the lens with a lens cap to avoid direct contact with the skin, as oils and acids on the skin may damage the lens. Use an ear cleaning bulb or a soft brush to gently remove dust from the lens, and avoid blowing with your mouth to prevent saliva from contaminating the lens . If there is dirt on the lens, you can wrap a soft lens paper around a cotton swab, dip a small amount of lens cleaning fluid, and gently wipe the lens in a circular motion. Be careful not to drip the cleaning fluid directly .
Moisture-proof and moisture-proof: The camera lens is afraid of water. Once water enters, it may cause fogging, mold growth, and even oxidation. In humid environments, such as the southern region, it is recommended to use a moisture-proof box or desiccant to prevent the lens from mold 2. Avoid using the lens in an environment with large temperature changes to prevent the generation of condensation water .
Dust-proof: The lens is easy to absorb dust, and you can add a UV protective lens in front of the lens. Remember to cover the lens cap when not taking pictures. When there is dust, blow it off gently and don't rush to wipe it.
Storage and transportation: When transporting and storing the lens, the aperture should be opened to the maximum and the focus should be set to infinity. If it is a zoom lens, the zoom ring should be turned to the telephoto end. This can prevent the lens from vibrating and colliding during transportation.
Adapt to different environments: Windy and sandy areas: Clean the lens after shooting to prevent dust from entering the lens and causing mechanical wear. High humidity areas: Use a moisture-proof box or desiccant to prevent mold. Avoid blowing the lens directly at the air outlet, and do not use a hot air gun to blow the lens to avoid mechanical damage. Low temperature environment: After shooting in a place below minus 20 degrees, do not use the lens immediately. It needs to be left alone for a while to prevent condensation inside. High temperature environment: Avoid direct sunlight and cover the front and rear covers when not in use. Clean the outer shell frequently to prevent microbial growth.
