I just bought a 20D (anxiously awaiting its arrival)! My other camera is a Rebel 2000 (film). I've read about some folks who inadvertently developed fungs inside their lenses. (I'm not sure if I've ever heard of anybody getting fungus in the body of their camera.) Having a digital SLR vs. film may not amount to a hill of beans as it relates to the subject of condensation and fungus in the lens and / or body, but what do I need to do in order to ensure that I protect my investment from damage? I've read about people using zip-lock bags (and some other type of bag, but I cannot remember the type). This may be a stupid question, but when do you use the zip-lock? Before going into an environment with a drastic change in temp? How much is not enough temp change to worry about? How long do I keep it in the plastic bag? What about the lens cap? On or off while heating up or cooling off? Inside or outside of the camera bag? Won't condensation form inside the zip-lock?
Sorry for all of the dumb questions, but I guess I don't really understand the ins and out of the subject.
Thanks.
