Yesterday was 34 degrees centigrade where I am. Very hot and humid. I was inside the reception area enjoying the chill of the AC when I decided to venture outside to where the wedding ceremony was to be held. Seconds after leaving he reception room I could see through the LCD my 24-105 was completely fogged up. I wiped it over and all was OK...for about 5 seconds before it fogged up again. With the ceremony about to start a vague panic started to crawl up my spine as I released that even with constant wipe-downs of the lens, the fogging was back, just as bad within seconds. Luckily for me, the ceremony was delayed for a while and finally after about ten minutes the lens stopped fogging up. Very close to the bone and something for people who work in these sorts of environments need to be aware of.

I can imagine the feeling, have had a few close calls over the years myself, (not weddings but on corporate stuff) I think it's important to keep a lens climatized if you can somehow.

I've experienced this many times.
Alister Chapman has a great tutorial on this - will he chime in here?
The problem is filming in tropical environments (Far East, Florida, Boston in August for that matter), and the use of aircon everywhere.
IIRC, there was a ziploc moisture proof bag involved... Two scenarios: cold outside, warm inside... and warm outside, cold inside.
Cold things brought into a warm environment get moisture all over them as the 'wet' in the air finds a chilly surface to sit on. Important to know when shooting in cold environments, ice and snow, important to know when you've been in a nice warm bar.
The opposite is also true: cold things brought into a warm environment get moisture all over them as the 'wet' air finds a chilly surface to sit on. Important to know when shooting in hot moist environments, when you've been in a nice chilly hotel foyer.
So at some point, a moisture-proof ziploc bag comes into play. Do you put your camera in the bag after shooting in heat, or do you put it in a bag before shooting in snow? No.
Alister - please correct me on this if I'm wrong...
When the camera's cold it must be protected from condensation. It can be cold because of snowy weather, it can be cold because of Dubai Air Conditioning. So you put it in the bag before you go into the Norweigan Bar, You put it in the bag before you exit the chilled hotel in the Floridian heat. Either way, you don't let the camera out of the bag until the COLD camera is the same HOT temperature as the surrounding climate.
The stress comes from a cold dry thing going into a hot (usually wet) environment.
For what it's worth, a trip to the toilet to blow hot air over your camera from the hand dryer, or a dip into the changing rooms to get a hair dryer, all help to work things out. Otherwise, you're dipping from one air conditioned space to another (believe me, I've done all three). Also handy to have either tin foil or the little hotel flannels handy to make a 'hat' for your camera in hot climates, and those little chemical hand-warmer sticks, with a bit of loose cotton over the camera, to keep it warm (including batteries).
