Tips for camera care in tropical climate?

I'll be travelling in Malaysia in the summer, and want to take the X Pro-1 with me, but I'm a little nervous about the effect of the heat/humidity on the camera - specifically, condensation forming inside the viewfinders etc when transferring from air-conditioned to humid environments.

Am I worrying unnecessarily, or are there tips I should be aware of?

TIA,

Tobes
