One of the best ways to protect your camera is to use a good and comfortable camera bag. This will protect the camera from physical shock and protect it from direct sunlight, moisture and rain. Furthermore, the bag helps you keep all accessories in one place without losing them when you want to use them next time. When you’re at home, you should consider a safe, or even putting a lock on your door!
Do not leave the camera under direct sunlight. Protect it with a towel or shade of some kind, so that rays from the sun does not hit directly on the camera or lens body. Direct sunlight on the camera can make it hot and damage the complex electronic circuit inside the camera. Make sure that the towel or any cover you put on top of the camera is not a dark colour since dark colours absorb heat and can make the camera hotter.
In case your camera is exposed to heat, do not use it immediately until it has cooled significantly. Using the camera when it is hot may damage the camera. In fact, try not to move the camera at all when it’s hot. Leave it to cool before handling to prevent any damage.
