AirCon issues

I've found that if moving from an air conditioned environment to the outside in very hot humid climates such as in Thailand, relatively cold cameras and lenses can almost instantly fog up with condensation and some of this can form on internal lens elements.  Usually it dries out OK but presumably any residual moisture is a perfect breeding ground for fungal spores.

Try putting equipment into sealed plastic bags and allowing it to warm up to the ambient temperature before opening the bag, which largely resolves the condensation problem.  This can take 15 minutes or more which is a bit of a pain but maybe that's preferable to suffering from condensation and fungal issues.
