FWIW, try storing your camera with desicant ( ie Moisture Munchers) and see if that will help improve the performance. When I travel to humid destinations, I will store the camera (when not in its housing) in a Zip Lock bag with the rechargeable discant packs in my A/C'd room. I have been surprised more than once about the "color" change in the desicant. And the camera and housing were completely dry when I removed the camera.
As a result of this thread, I've been wondering lately about storing the camera if it's not being used for a while. Putting it in an airtight bag in the fridge might slow down any corrosion or detector degradation that seems to happen with certain models. Just leave it in the bag for an hour or two after taking it out of the fridge, to avoid condensation inside. The operating specs typically go down to 0C, and those temperatures won't hurt the batteries either. If anything, it'll slow down their self-discharge.
