For about 30 minutes before you go into the tropical house or the like, keep your camera under your jacket so that it is fairly warm before you enter the building.

When you use it just do so and then put it back under your jacket.

Condensation is caused by the heat hitting the cold surfaces so if you try and warm your camera up it will keep this to a minimum.

take some lens tissues with you and if it does get condensation on it then just wipe it off right away.

Hello Laurz.

you might find the video below quite interesting!

Now, as was mentioned before, condensation might be the bigger problem you might be exposed to here. Many zoos (with flowers/butterfly rooms where humidity and temperature are quite high) also have a device at the entrance where you can "condition" your camera (lens) so no condensation occurs inside your lens and you are actually able to take photos.

Condensation is not recommended and you will find it every time you have a strong change in temperature. For example, if you go out, photographing below zero and suddenly enter a properly heated place, unwanted condensation will occur.

Also, some tips include:

- Dropping your lens in a ziplock bag before changing rooms (hand warmer inside the bag as well)

Hope you have your question answered. If anything, ask back!

Steam can damage your camera (if you are talking about steam engines or steam coming out of a coffee pot).

If you are talking about a tropical enclosure, then that is something totally different.

I'm sure it's not the best environment for your camera (but then again, it's not the best environment for anything, like paper or electrical components)

When I went to the tropical enclosure at my local natural history museum (which also included butterflies), my digital SLR camera was fine. I didn't acclimate it (plus I didn't have an hour to wait around with my camera - people would have thought I was creepy just standing around).

The main problem is condensation on the lens... Bring your camera up to temperature by warming it up with your car heater or similar... I've shot at a butterfly farm a few times and the only problem is condensation on the lens... It doesn't last long though, particularly if the camera is already warm.

It should be OK. Just don't get the camera wet. I've used a DSLR in Malaysia - it's hot and steamy there too.

Obviously if your camera is cold, you could get some condensation on the lens. Keep your camera warm before you go in.

Not a problem! Most cameras can handle this if U use common sense. I usually drape a small cotton towel over my camera as I enter and exit such places. That seems to bridge the temperature gaps. Also soaks up excess moisture when needed.

Perhaps, the condensation may damage the camera by short-circuiting, or produce vapour droplets in the lens. However, this is pretty rare to happen and won't really happen if you slowly put the camera in cold air to avoid condensation.

I've been to tropical gardens numerous times, never had an issue but, I was shooting nikon, not that flimsy 1000d.

If there's a device for clearing fogged glasses, use it.
