Hi all, just came back from a month long trip to China, Hong Kong, and Japan. Took so many photos that i'll be posting up eventually, but thats a whole other story.

I was wondering hoe many other people have had problems with their camera lens fogging up?

I tryed a search on this topic, because i think i rememebr someone mentioning it a while ago, but i couldnt seem to find any other threads.

Lens fog had never happened to me until i was in China. The MASSIVE humidity and temperature changes between indoors and out seemed to cause my lens to fog up (i think?).
Is there a way to avoid this? Any tips on preventing it from happening? Or quick ways to get rid of it after its happened?
It was quite frustrating at times, as it seemed to happen when i was in a really interesting area, and prevented me from taking photos from time to time.

It might be a dumb question, but i thought i'd just ask anyway.

cheers
