How to deal with dust on the lens of a digital camera

Hello! The correct method should be to first blow off the dust on the surface of the lens with a blower (also called an ear cleaning ball). Such blowers are sold in general photography stores, and the price ranges from a few yuan to dozens of yuan, but it requires Be careful not to use a self-service compressed air tank, because the pressure is too high, which may blow dust into the gaps in the lens. Do not blow directly with your mouth. In that case, a lot of saliva particles will be blown to the surface of the lens, which will cause more damage. It’s difficult to handle. If the dust on the surface of the lens cannot be cleaned with a blower, we can also try to use a soft brush to clean the lens. Generally, dust and other dirt can be removed. For stubborn stains, such as finger marks, we have to use suede. , lens cleaning cloth or lens paper combined with lens cleaning fluid to clean. When scrubbing, be careful not to squeeze the lens surface too hard, as the lens surface is covered with a fragile coating that can easily be wiped off due to vigorous cleaning.

When buying lens paper, be sure to buy it from a regular professional photography store. Do not buy low-quality lens paper just for the sake of cheapness. This kind of lens paper often contains a certain amount of wood pulp, which will cause damage to the lens. Seriously damage the coating on the digital camera lens, and you may "regret it" by then. There is a lot of debate about whether to use lens cleaning fluid to clean the lens. Some inferior brand-name cleaning fluids can indeed cause damage to the lens. Therefore, we recommend that if you can simply use suede and other tools to clean the stubborn stains on the lens, then you do not need to use them. When using cleaning fluid as a last resort, you must be careful not to use too much, and do not let the cleaning fluid get outside the lens, because some cleaning fluids contain acetone, which can easily cause the black lens edges to fade, which can seriously It will also cause deformation around the lens, so remember! Roll the lens paper into a short cylinder, and then wipe the lens with the flat end of the cylinder. Wiping method: Wipe from the center of the lens in a spiral motion outwards. Try not to let the edge of the lens paper come into contact with the lens to avoid leaving paper scraps on the lens.
