I learned this from SCUBA diving. You can use your own spit to prevent fogging in face masks. Today was the first time I took my DSLR into a cave and low and behold my lenst began to mist up. Rub a little spit on it. Voila. If you have an aversion to spitting on your very expensive lens, there are some commercially purchasable defogging applications that you can get at SCUBA stores.
Good luck,
