He has not cleaned the camera. I was about to send him the cleaning supplies, but after he reported the problem, I have held off. I live in Hawaii, on the Leeward Coast (dry climate) of O'ahu, where with trade winds, the humidity rarely exceeds 85%. This is a very temperate climate for a camera of this ruggedized contruction. The camera was kept in a closet in the coolest room, on the north, shaded side of my condo. Temperatures range from 65-80°F in that room.
My son lives in Santa Fe, New Mexico. Temps there range from 20-85°F at 7,200 ft elevation with greater variation in wind, humidity, temperature, and types of precipitation/snow. The camera has only been in his possession for 3+ weeks. He has since stored it in his condo in low humidity (<80%) with indoor temps in the 68-72° range, except for the brief periods in which he captured the photos. I sent him a PDF file of the large manual and he was beginning to try to master the basic and intermediate settings.
85% humidity and temperatures rising and falling from 65-80 degrees is ideal for condensation.
Ruggedized and weather sealing has very little impact on 2 years of rising and falling temperatures in relatively high 85% humidity.
Any contamination left from your last wet cleaning, would act as a magnet for condensation and those areas that attracted the condensation would get further contaminated getting worse and worse over 2 years..
Have your son take a photo of blue sky at f/22 and see what it looks like.
My guess is it just needs another sensor cleaning.
