This video shows us the method to protect your lens. This can be done by putting the lens caps. The cap for the part of lens going into the camera can be screwed on to the lens. It stops dust from getting on to the lens surface. The front part of the lens can be protected by a lens cap which can be put into the position and pulled out when needed. You can also put a filter on the lens. The filter can be used to protect the lens in case you drop it in the sand and any other similar condition. Instead of cleaning your lens from time to time, you can clean your filter. Filters are cheaper than the lens in case you drop the camera and it gets broken. This finishes the video.
