How to protect SLR cameras from dust

One of the most troublesome things when using a SLR camera is dust protection. Because if you don't use the camera for a few days or change the lens frequently, a lot of dust will enter, making it very troublesome to clean. Therefore, dust prevention work is an essential task. Although it is a very troublesome thing, it must be done well, otherwise it will affect the service life of the camera and lens. The poster can take a look at some of the dust prevention tips I found below. 1. Commonly used lenses should always be screwed on the body as standard. There is no need to unscrew the lens for storage when not shooting. This can reduce the chance of dust contamination. 2. When changing the lens, do not twist the lens against the wind. Use the camera bag you carry with you as a dustproof box. Open the cover of the camera bag, turn the lens downward, unscrew the lens, and put the lens into the camera bag. At the same time, remove the tail cap of the lens to be replaced and quickly insert it into the bayonet and tighten it. 3. Don’t rush to take pictures after changing the new lens. First check whether there is dust on the mirror through the viewfinder, because if there is dust at this time, most of it will fall on the mirror. If you start the shutter to shoot at this time, the dust may The airflow formed by the lifting and falling of the reflector will stick the dust to the CCD through the opening of the shutter. So first check to see if there is no dust on the reflector while shooting. Basically, it will not take long. If dust is found, as in the second 2-step operation: remove the lens, use air to blow down the body bayonet several times, and then put the lens on to shoot.
