Honestly now, how many of you have gone on vacation and pulled out your cameras only to witness your camera lenses fog up in a split second. Come on now, you can admit it, it has happened to all of us. As a result of this most annoying of summertime hazards to your camera, you had to wait hours for it to clear and missed dozens of images. This situation occurs when you take your camera from a dry cool place, like your air conditioned room or car, out into the heat and humidity. Since I'm from the east coast, this can occur almost every summer day!!! The picture below is case in point, I was down in New Orleans thinking I took all precautions for the 98% humidity, but obviously I did not. I did not think about my camera body and the glass in front of the sensor fogged.
OK, so how do you prevent this from happening to your lenses. The first step in preventing the fog is to keep your lenses and camera locked tight inside zip lock bags. This will help with condensation and will accumulate on the inside of the bag and not the lens. Second step, always keep all your equipment zipped up tight inside your camera bag. Last but not least, and it may seem a bit of over kill, but, keep you camera in the bathroom of your hotel room with the door closed. Since the air conditioning is usually only in the bed area, the bathroom with the door closed will never get as cool as the rest of the room. Keep to these simple rules and you will not miss shots such as this.
