got a pany ZS3 and after about 30 minutes into the dive there is fog inside the housing.
I use the dessicant stuff...and even changed the little mini bags between dives and fog persists. It seems that the camera gets warm after shooting video and I've turned off the continuous on switch...so the camera is not on all the time. At any rate I assume that the inside temp is warmer than outside and creates the fog.
What am I am doing wrong or is there some special stuff I should be using? Any tips, ...?....should I place the camera in a refridge or cooler before diving?
FWIW...the camera does pretty good considering there's not a lot of adjustments

First, it's not a leak, it's normal. There is a certain amount of humidity in the air, and possibly some parts of your camera have absorbed moisture too. When your camera heats up due to shooting video or using the rear display or flash, it bakes out any moisture in its parts and increases the temperature inside the housing. This increases the amount of warm humid air inside the case. Your lens port is in contact with the colder outside air, so the fog condenses on it.
A double pane port glass would reduce that. Very few ports have double panes.
You can minimize the humidity inside your camera by opening it only in low humidity spaces, such as an air conditioned room. A boat on water is a very high humidity space, so to avoid fogging, try to minimize opening it on the boat. Desiccants such as silica gel (in the white packets shipped with many imported electronic items) can absorb some moisture -- but they are not perfect. So, close up in a dry space, and use silica gel desiccant bags.
