I'm currently 1.5 weeks into a 5 week stay in the Dominican Republic. I'm not staying in a resort, but at a cocoa farm. Obviously, because the DR is a tropical country, its very very humid here and it rains a LOT (3 times a day at least!) In the frenzy to get get ready to leave, I forgot about the complications that come with camera gear and high humidity. None of my gear has any issues, but I was wondering if there is any preventive maintenance I can do while down here? Also, since my 100mm macro L lens is "sealed" should it be safe from fungus?
The only cleaning stuff I have with me is a lens pen, and some sensor swabs.
