What do we often do when we take the camera out of its case? We usually open the body cap from the front body of the camera and open the lens rear cap from the back end of the lens. At that point of time, unknowingly we touch two things which can be the main source of dust and dirt that can directly enter into the sensor camera. How we put those two caps can be one of the factors which can affect the cleanness of sensor and lens of our camera. The following is the detail explanation.
Just imagine if we keep the body cap in our pants’ pocket where there are so many dirt and dusts that can stick onto the cap. Or accidentally, we drop it to the ground and when we want to place it back to the camera, there are already so many dusts and dirt that fall to the sensor, dreadful right? So is the lens cap. If the dust gets into the insides, the back side of the lens will get awfully dirty and it finally falls out to the sensor. Apart from getting dusts which stick onto the lens cap and the body cap, possibly, it will take mold spore onto them. This can lead to a mold growth if the spore falls on the surface of the sensor or to the lens of your camera.
Well, actually there is a safe and easy way to store your body cap and lens rear cap. You just need to attach both of them together and rotate them until they get tight, so the inside parts of both caps are protected from dirt and dusts. After that, you can freely put them into your pocket or place them back onto your camera case or wherever you like. It is very important to keep them closed tightly since this can reduce the risk of getting dust and dirt on your sensor camera. Indeed, these are very simple tips, yet very important to keep the sensor and the lens of your camera clean.
