Just wondering if anyone here lives where there is a lot of humidity and how that has an effect on your camera such as moisture getting inside your camera or fogging the lens etc...?

I went to SE Asia for 2 months and I got fungus growing in one of my lenses.

Condensation shouldn't be too much of an issue as long as the camera isn't a lot cooler than the air. If your camera is cooler you should probably warm it up in a plastic bag. For the long term it might be worth some sort of dry safe to keep the expensive stuff in. rechargable silica gel packs could help.

Tip - Either save up those gel packs when you buy stuff or buy a bunch of them (Amazon sells them) and put them in your camera bag to soak up excess moisture from the air.

You don't want mold growing in your equipment.

Yes, sometimes. I changed the lens of a Canon 300D (years ago) in a thunderstorm in the Seychelles and the humidity messed the camera up. Ever after it was inclined to produce and Err message whenever the humidity rose.

In general, don't take a cold camera into a hot, humid environment. If it is in an air-conditioned room put it in a ziplock bag and leave it outside until it reaches thermal equilibrium before removing it from the bag. Water condensing inside it can do nasty stuff.

i live in the tropics and from years of dealing with humidity this is what i do and suggest you give it a try.

if you only have a fan room, take your gear out of your bag and put your gear where there is constant air circulation. never put your gear in a dark place with no circulation for extended periods.

if you are in AC then if possible put your gear in a room that has no AC and a fan. if it must be in AC, i put my gear in the bag so there is some insulation between the AC and my gear. then an hour before you head out, turn off the AC, take the gear out of the bag, and open windows. this allows your gear to slowly acclimatize.

i never use silaca gel, but there is no reason for this, i think where i am it's too humid for silaca gel to have a real effect, but that is just my guess.

from my experience i think the two most important things are air circulation, and slow acclimatization from AC to warm with an emphasis on air circulation. also consider some lenses mold up faster than others, fixed focal lengths i have noticed seem to get moldy more often than zooms, my guess is that the zooms create a vacuum when you move them, thus giving air circulation. that is only a guess though.

if you are only in humid conditions for a month or so, i don't think you have too much to worry about though.

I practically live in the middle of the jungle, and many years ago I had to pay the expensive consequences of ignoring the nasty effects of humidity on photographic equipment.

All my equipment is now stored in a transparent cabinet where they get good light 24 hours a day. 
Windows and doors are always open when humidity is below 55%.  As soon as humidity goes above 55%, I close windows and doors and a powerful dehumidifier starts working to keep humidity below 55%.

Also, I have little dehumidifiers like this one http://www.amazon.com/dp/B000H0XFCS inside all my backpacks and cases.
