OK, I did something very very stupid. I know it. I just wasn't thinking. :( In a nutshell, I didn't follow the advice here: How do I prevent condensation on a lens when outdoors?
So it's a very hot and humid day here... 95 °F (= 35 °C) and 70% humidity... the heat index is hanging around 110. I'm inside in a well air conditioned building, my camera was sitting in it's bag, very close to the air conditioner (dumb placement, I know) so it is very cold. I just grabbed it and walked out side to get a shot of a bird. The lens fogged up almost immediately. I then realized my stupidity and came back inside. After drying the front element of the lens, and the lcd and the view finder eyepiece, I sighted out a shot and realized it's still fogged, so the internal surfaces are too. :(
How best can I recover from this incident without condensation damage to the camera? (I've already powered it down and pulled the battery.) Should I take the lens off? (this is a 5D2 with an L series lens)
