Recently I was in a trip in a very hot area. The hotel room was very cold because of the air condition. and once I use my camera I realized that the lenses is very foggy I had to keep it in a warmer place for a while to use it. because all photos produced are foggy. this called condensation where the water change from its gaseous form into liquid water. and of course it is a very dangerous for the camera.
After a while I recognize that my 18-55 AF lenses didn't work properly specially the Auto Focus system. I had to turn off the camera and remount it again to get it back to its function.
I was wondering if that happened while the camera and lenses in their bags and well stored. So it is possible to happened to any glassy surface including the sensor.
My question is does is effect the sensor as well as the AF mechanism of my lenses? and after the condensation, do I have to clean my sensor? what should I do to maintain my gears in that conditions? do I have to get a special equipment like a waterproof box?
I know there is some question talking about humidity and the camera but non of those question concern about the AF lens mechanism and the sensor cleaning.
