2. When it’s cold out, keep the camera as warm as possible by keeping it under your coat. Always carry extra batteries. Those in your camera may weaken at low temperatures just as your car battery weakens in winter. Prevent condensation when taking the camera from a cold area to a warm one by wrapping the camera in a plastic bag or newspaper until its temperature climbs to match that of its environment. If some condensation does occur, do not use the camera or take it back out in the cold with condensation still on it or it can freeze up camera operation. Remove any batteries or memory cards and leave the compartment covers open until everything dries out.
3. Never place the camera near electric motors or other devices that have strong magnetic fields. These fields can corrupt the image data stored in the camera.
4. Always protect equipment from water, especially salt water, and from dust, dirt, and sand. A camera case helps but at the beach a plastic bag is even better. When shooting in the mist, fog, or rain, cover the camera with a plastic bag into which you’ve cut a hole for the lens to stick out. Use a rubber band to seal the bag around the lens. You can reach through the normal opening in the bag to operate the controls. Screwing a protective filter over the lens allows you to wipe off spray and condensation without damaging the delicate lens surface.
