Going from dry to humid areas quickly can indeed cause the lens to fog (and on the inner elements on some lenses). Some of the "L" lenses are sealed, and those would not let moisture into the lens, and only fog on the front element would be an issue.
The best way around this is to either have two bodies (one for outside, and one for inside, kept in a sealed bag with lots of dessicant in there), use a sealed lens (and a sealed body... yikes), or just wait for the fog to lift once you've gone inside. That could take a while, depending on how extreme the temperature differences are.

the fog was on the outside so there was no problem with the seal.
yeah..i guess i'll wait for the fog to lift.

aside from problems with condensation on the interior elements and all that...
why don't you just wipe it off? :)

Oh yeah -- option 4... though, wiping it off could scratch the front element/filter if there was some dust on there, and you drag a cloth across the face. I use a microfiber cloth that I use for my glasses to keep the front element clean in cases like this - it won't scratch the glass.

I tried wiping. It would resuface in a matter of seconds and the image just wouldn't turn up without being foggy.

I guess I'll just wait for it to get accustomed to the climate.

In a typical hot and moist greenhouse the lens will fog faster than you can lift the camera to your eye. So wiping it off will not help as long as the lens colder than the environment. You could try a heater or the the sun or visiting a dry and hot greenhouse to get the lens temperature above the ambient temperature. Otherwise you just have to wait until the lens warms up. This will happen faster if it is out of the bag with the lenscap off. You may need to wipe it off once its warm if you don´t have the patience to wait for evaporation to take care of the condensation. The equipment may need 15 or 30 minutes to warm up sufficiently.

:o) Not quite the same problem, my friend left his camera on the ground at a flickr meet recently and when he picked it up this is what we saw

The "fog" may actually be condensation on the lens.
If it is condensation, it is due to the difference in temperature on the lens and the environment. Waiting for the temperature to even out is the only way to get rid of the "foggy" lens. I just had this very same problem shooting a sunrise near the Gulf Of Mexico...a very, very humid area.

If you change humidity (indoors, cold, outdoors hot) or rapid temps, putting the camera in a plastic bag can help. I keep mine in a padded case so the temperatures equalize over time. Never have a fogging problem that way.

I get this just from stepping outside. Humid Hong Kong weather...
Even the Canon instruction booklet tells you to keep the camera and lens in an airtight bag until it's the same temperature as the ambient one, to avoid condensation. Condensation is not only a nuissance on lenses, but could oxidize your electronic contacts and other parts inside the body.

The plastic bag is probably important if you live in Hong Kong or Singapore where you have the condensation problem every time you take photos outdoors. If you just go to a greenhouse once or twice a year the condensation will not damage your equipment.

I agree with |Andreas here, if it's not regular just wait for the lens to warm up and you'll be fine. If you do it every day it would be a good idea to use a plastic bag to prevent moisture getting to the lens or camera.
Just let the camera warm up and it'll be fine. Anyone who wears glasses will be very familiar with this problem!
