So, what is the alternative? Use your camera’s case when going in and out of extreme temperatures. Think of that case as a coat. When you need a coat, your camera may need one as well. You can take your camera out of its case to take those scenic cold weather pictures. Just remember to put the case back on before entering a warm environment -- especially if you expect to use the camera right away. Leave the camera in its case for at least 5-10 minutes. This will help the camera adjust to the warmer temperature a little more gradually. Chances are, you won’t even need to wipe down the outside of your lens. If the lens still fogs up, be patient. Let the fog disappear by itself. If the camera has been allowed to adjust to the new temperature gradually, you will be ready to take those family pictures in no time at all!
